Optimized biotransformation of acid-treated water melon peel hydrolyzate into ethanol / Biotransformação otimizada de hidrolisado de casca de melancia tratada com ácido em etanol

Abstract Today, global focus of research is to explore the solution of energy crisis and environmental pollution. Like other agricultural countries, bulk quantities of watermelon peels (WMP) are disposed-off in environment as waste in Pakistan and appropriate management of this waste is the need of hour to save environment from pollution. The work emphasizes the role of ethanologenic yeasts to utilize significant sugars present in WMP for low-cost bioethanol fermentation. Dilute hydrochloric acid hydrolysis of WMP was carried out on optimized conditions employing RSM (response surface methodology) following central composite design (CCD). This experimental design is based on optimization of ethanologenesis involving some key independent parameters such as WMP hydrolysate and synthetic media ratio (X1), incubation temperature (X2) and incubation temperature (X3) for maximal ethanol yield exploiting standard (Saccharomyces cerevisiae K7) as well as experimental (Metchnikowia cibodasensisY34) yeasts. The results revealed that maximal ethanol yields obtained from S. cerevisiae K7 was 0.36±0.02 g/g of reducing sugars whereas M. cibodasensisY34, yielded 0.40±0.01 g ethanol/g of reducing sugars. The yeast isolate M. cibodasensisY34 appeared as promising ethanologen and embodies prospective potential for fermentative valorization of WMP-to-bioethanol.

Resumo Hoje, o foco global da pesquisa é explorar a solução da crise energética e da poluição ambiental. Como em outros países agrícolas, grandes quantidades de cascas de melancia (WMP) são descartadas como resíduos no meio ambiente no Paquistão, mas a gestão adequada desses resíduos é a mais recente solução para salvar o meio ambiente da poluição. O trabalho enfatiza o papel das leveduras etanologênicas para utilizar açúcares significativos presentes no WMP para fermentação de bioetanol de baixo custo. A hidrólise de ácido clorídrico diluído de WMP foi realizada em condições otimizadas empregando RSM (metodologia de superfície de resposta) e seguindo o projeto de composto central (CCD). Este projeto experimental é baseado na otimização da etanologenesis envolvendo alguns parâmetros independentes importantes, como hidrolisado de WMP e razão de meio sintético (X1), temperatura de incubação (X2) e temperatura de incubação (X3) para rendimento máximo de etanol explorando o padrão (Saccharomyces cerevisiae K7) também como leveduras experimentais (Metchnikowia cibodasensis Y34). Os resultados revelaram que os rendimentos máximos de etanol obtidos a partir de S. cerevisiae K7 foi de 0,36 ± 0,02 g / g de açúcares redutores, enquanto M. cibodasensis Y34 rendeu 0,40 ± 0,01 g de etanol / g de açúcares redutores. O isolado de levedura M. cibodasensis Y34 apareceu como um etanologeno promissor e incorpora um potencial prospectivo para a valorização fermentativa de WMP em bioetanol.

Antiadhesion and antibiofilm potential of Fagonia indica from Cholistan desert against clinical multidrug resistant bacteria / Potencial de antiadesão e antibiofilme de Fagonia indica do deserto do Cholistão contra bactérias multirresistentes clínicas

High resistance to antimicrobials is associated with biofilm formation responsible for infectious microbes to withstand severe conditions. Therefore, new alternatives are necessary as biofilm inhibitors to control infections. In this study, the antimicrobial and antibiofilm activities of Fagonia indica extracts were evaluated against MDR clinical isolates. The extract exhibited its antibiofilm effect by altering adherence and disintegration of bacterial cell wall. Fagonia indica has antibacterial effect as minimum inhibitory concentration (MIC) values ranging from 125 to 500 µg mL-1 and minimum bactericidal concentration (MBC) value was 500-3000 µg mL-1 against multidrug resistant (MDR) clinical isolates. The extract exhibited its antibiofilm effect by altering adherence and disintegration of bacterial cell wall. Fagonia indica had antibacterial effect as minimum inhibitory concentration (MIC) values ranging from 125 to 500 µg mL-1 and minimum bactericidal concentration (MBC) value was 500-3000 µg mL-1 against MDR isolates. The maximum inhibitory effects of Fagonia indica chloroform extract on biofilm formation was observed on Staphylococcus aureus (71.84%) followed by Klebsiella pneumoniae (70.83%) after 48 hrs showing that inhibition is also time dependent. Our results about bacterial cell protein leakage indicated that MDR isolates treated with chloroform extract of Fagonia indica showed maximum protein leakage of K. pneumoniae (59.14 µg mL-1) followed by S. aureus (56.7 µg mL-1). Cell attachment assays indicated that chloroform extract resulted in a 43.5-53.5% inhibition of cell adherence to a polystyrene surface. Our results revealed that extracts of Fagonia indica significantly inhibited biofilm formation among MDR clinical isolates, therefore, could be applied as antimicrobial agents and cost effective biofilm inhibitor against these MDR isolates.

Concomitant Outbreaks of Yellow Fever and Hepatitis E Virus in Darfur States; Sudan; 2012

Introduction: Yellow fever (YF) is a vector-borne disease transmitted to humans by infected Aedes mosquitoes; while hepatitis E virus (HEV) is a waterborne disease that is transmitted through the fecal-oral route. Both diseases have very close clinical presentation; namely fever; jaundice; malaise; and dark urine; they differ in severity and outcome.Methodology: In this cross-sectional; laboratory-based study; an attempt was made to measure the correlation of concomitant YF and HEV infection in Darfur States during the previous YF outbreak in 2012.Results: Results found concomitant outbreaks of YF and HEV at the same time with very weak statistical correlation between the two infections during the outbreak period; with Cramer's V correlation 0.05 and insignificant p value of 0.86.Conclusions: This correlation indicates that clinicians and care providers in tropical areas have to deal with clinical case definitions used for disease surveillance very carefully since prevalence of HEV infection is relatively common and this increases the possibility of misclassification and missing YF cases; particularly initial index cases; in a season or outbreak

Evaluation of attributes to hyperbilirubinaemia in neonates in a tertiary care hospital in the Dhaka city.

Objective: The study was aimed to evaluate the attributes related to hyperbilirubinaemia among neonates. Materials and methods: A total number of 120 neonates with hyperbilirubinemia included in the study. Data were collected using hospital records and by face-to-face interview of mother of those neonates using a predesigned questionnaire. Data were expressed as mean±SD and number (percent) as appropriate. Both descriptive and inferential statistics were considered in data analysis. Statistical analyses were performed using SPSS Software. Result: Of the total neonates, 57% were baby boys. In age group of 2nd to 7th days were 59.2% of neonates. According to the birth weight, neonates distribution was 38.3% in very low (<2000g), 42.5% low (2001-2500g) and 19.2% normal (>2500g) birth weight group. ABO incompatibility was found in 14.2% and Rh 8.3% cases of hyperbilirubinaemia. Birth trauma was found in 7.5% and congenital anomalies 3.3% neonates. Pre-maturity (gestational age <37 wks) was found in 73.3% cases. Normal vaginal delivery was performed in 59.2% of cases. Exclusive breast feeding was given by 43.33% mothers. Of the mothers 93.4% were housewives. Thirty percent (30%) of mothers were adolescents (<20 years) and 27.5% young adults (20 to 25 years). Of the 120 mothers 56.7% had primary level education. Low birth weight (<2000g to 2500g) neonates had significantly higher (p<0.005) serum bilirubin than the normal birth weight counterpart. Among the neonates of the mothers with GDM, 9.2% had serum bilirubin level above 20mg/dl and the distribution showed significant association (p<0.005). Conclusions: It is concluded that low birth weight and prematurity remained to the major causes of neonatal hyperbilirubinemia in neonates. Other common causes, particularly ABO and Rh incompatibility, are also present which could be avoided by meticulous clinical practice and burden of neonatal morbidity and mortality related to hyperbilirubinemia can be reduced.

Factors associated with dengue fever IgG sero-prevalence in south Kordofan state, Sudan, in 2012: Reporting prevalence ratios

Dengue fever [DF] is a vector-borne virus transmitted to humans by infected Aedes mosquitoes. In this study, we identified the most important factors associated with the prevalence of IgG antibodies in a border state between Sudan and the new republic of South Sudan. To quantify the association of specific factors with the prevalence of DF IgG antibodies in Lagawa among subjects aged 16-60 years in 2012. Analytical cross-sectional community-based study conducted in Lagawa in 2012. Indoor mosquito breeding was the most significant predictor affecting DF IgG serology. Household water storage was also strongly associated with the presence of IgG antibodies. Residence in urban areas, younger age and a history of travel to the Red Sea State were significant predictors of DF IgG seroprevalence in South Kordofan state. Indoor [household] behaviors associated with DF infection should be modified to mitigate the infection risk in the study area. Awareness should be raised regarding DF in Lagawa to ensure community participation in all control measures, and the surveillance system at the border between Sudan and the republic of South Sudan should be strengthened

Comparison of C-reactive protein among controlled, moderately controlled and uncontrolled diabetic subjects in a Bangladeshi population.

Poor glycemic control is significantly associated with the development of macrovascular complications of diabetes. C-reactive protein (CRP) is considered as a sensitive and independent risk factor for cardiovascular events. The aim of this study was to compare elevated CRP among controlled, moderately controlled and uncontrolled diabetic subjects in a Bangladeshi population. CRP and glycosylated hemoglobin A1c (HbA1c) were measured in 226 confirmed diabetic subjects purposively and randomly. Elevation of CRP in the moderately controlled (relative risk 1.64, P<0.01) and uncontrolled diabetic subjects (relative risk 1.8, P<0.001) were significantly higher than controlled diabetic subjects. HbA1c was significantly associated with the likelihood of elevated CRP in the moderately controlled diabetic subjects (OR:2.87, 95% CI: 1.41 to 5.87, P<0.01) and in the uncontrolled diabetic subjects (OR:3.83, 95% CI: 1.94 to 7.58, P<0.001). This study revealed that the likelihood of elevated CRP is associated with the increase of HbA1c in diabetic subjects.

Cadmium: Toxicity and tolerance in plants.

Of all the non-essential heavy metals, cadmium (Cd) is perhaps the metal which has attracted the most attention in soil science and plant nutrition due to its potential toxicity to humans, and also its relative mobility in the soil-plant system. This review summarizes the toxic symptoms of Cd in plants (i.e. growth retardation, alterations of photosynthesis, stomatal movement, enzymatic activities, water relations, interferences with mineral uptake, protein metabolism, membrane functioning, etc.) but also includes the mechanisms of cadmium uptake, translocation and deposition. Moreover, it also throws light on chelation, including identification of Cd ligands present in cytosol and vascular tissue. Cadmium-induced oxidative stress is also considered as one of the most widely studied topics in this review.

The fly ash influenced the heavy metal status of the soil and the seeds of sunflower. A case study.

In this study, four cultivars of sunflower (Helianthus annuus) were grown in the sandy loam soil, supplemented with graded (v/v) quantity (0, 20, 40, 60, 80, 100%) of the fly ash, released by the combustion of the coal from the thermal power plant. The presence of fly ash in the soil increased its porosity, water holding capacity, pH, E.C., C.E.C., the content of sulphate, carbonate, bicarbonate, chloride, phosphorus, potassium, calcium and various trace elements. However, in the seeds, except Fe, Pb, Mn and Zn, and other heavy metals remained untraced up to 40% of the fly ash, above that their quantity slightly increased but the values are very much under the permissible limits.

Response of sugarcane to treated wastewater of oil refinery.

The crop of sugarcane (Saccharum officinarum) was grown at the agricultural farm of the Mathura Oil Refinery in a simple randomized block design. The experimental plots were irrigated with ground water (GW) or treated wastewater (TW) as and when required The plants gave better response to the latter than the former. The quantity of the required nutrients was comparatively more in TW than GW. The soil receiving wastewater did not show any significant change in its physico-chemical characteristics. The soil accumulated all the heavy metals but the plant samples receiving TW only exhibited the presence of Ni, Pb and Zn whose values are far below the permissible limits.

Studies on the mitochondria in protein-energy defficient rats

The effect of protein energy deficiency on the electrolyte content and the swelling of mitechondria isolated from rat liver, kidey and thigh muscle was studied. The level of sodium was insignifcantly increased in the three types of mitochondria. Potassium concentration in the kidney mitochondria was slightly decreased, while in the liver and muscle mitochondria it was not changed. Calcium level did not show marked variations, while magnesium concentration was significantly increased in the liver mitochondria only. It was found that liver and kidney mitochondria isolated from the malnounshed animals were swollen. Inorganic phosphorous estimations showed no significant change. It was concluded that protein-energy malnutrition could interfere with the biochemical processes carried out by mitochondria, which may lead to a serious interference with the energetics of the cell

Effect of protein-energy malnutrition on the electrolyte level and total proteins in rat tissues

The effect of protein and energy deficilncy on the electrolyte levels in rat serum, kidney, liver and thigh muscle was studied. The present study revealed a significant increase of serum sodium in the malnourished animals as compared with the control group. The kidney was the only tissue which showed a marked demrease in the potassium level. Calcium was significantly decreased. In both the kidney and the thigh muscle, While magnesium was markedly decreased only in the liver. Inorganic phosphorus level was decreased significantly in the serum, kidney and liver. Total protein estimations revealed that only the liver and muscle may contribute in the compensation of protein deficiency. The results of this work were compared with the data reported in the literatuer
