ABSTRACT

Aim: The current venture, were made to evaluate the inhibitory effect of Trigonella foenum seed Extract and ZiO2 Nanoparticles on some selected species of Fungi and Bacteria. Materials and Methods: two bacterial species included Pseudomonas aeruginosa and Staphylococcus aureus and three fungal species which is Cryptococcus neoformans, Candidda albicans and Chaetomium were used to evaluate the antibacterial activity of Trigonella foenum Extract and ZiO2 Nanoparticles. Results: This study showed that the Zirconium Oxide (ZiO2) nanoparticles have antifungal and antibacterial activities on the isolates of Cryptococcus neoformans, Candida alicans and Staphylococcus aureus, respectively. While the antimicrobial activity of Zirconium Oxide nanoparticles on the Chaetomium and Pseudomonas aeruginosa was negative. All tested fungi and bacterial isolates were found to be sensitive to Trigonella foenum seed extract, the results of the compination of the ZiO2 Nanoparticle and the Trigonella foenum seed extract were poisitive for all tested fungi isolates and bacterial isolates. The XRD analysis was done for Zirconium Oxide nanoparticles and the result showed that the biocrystallization on the surface of the Zirconium Oxide manoparticles. The average partides size was about (29.8) nm. Conclusions: This investigation conclude that the use of Trigonella foenum seed Extract has the effect of killing all bacteria and fungi under study, result indicate the Trigonella foenun seed Extract best antibacterial efficacy than the ZiO2 together (AU)

ABSTRACT

Se halló 16 a 60 esporos fúngicos/litro aire y de 100 a 100.000 esporos de actinomicetos termófilos/g polvo del piso en los secaderos de tabaco. Los hongos eran Alternaria sp (21 por ciento), Aspergillus sp (15 por ciento), Asp. fumigatus (7 por ciento), Asp. glaucus (5,5 por ciento), Asp. nidulans (13,3 por ciento), Chaetomiun sp (2,3 por ciento), Chrysosporium spp (5,5 por ciento), Cladosporium sp (3,1 por ciento), Curvularia sp (0,8 por ciento), Dactylaria sp (3,1 por ciento), Nogrospora sp (5,5 por ciento), Penicillium spp (11,7 por ciento), Talaromyces sp (2,3 por ciento) y no identificado (3,9 por ciento). Los Thermoactinomyces eran Tha. thalpophilus (66,6 por ciento), Tha. sacchari (6,7 por ciento), Tha. vulgaris (6,7 por ciento) y otros Tha. spp (20 por ciento). También el humo de cigarrillos contenía esporos viables de Thermoactinomyces. El 7 ñ 3,3 por ciento de los trabajadores tenían anticuerpos anti-Tha. thalpophilus demostrados por doble inmunodifusión

ABSTRACT

Mediante la selección de 8 compuestos plásticos utilizados en el mercado, adquiridos a la firma Aldrich Química SRL (Alemania), se valoró su capacidad de ser asimiladas como única fuente de carbono in vitro, por 2 grupos de microhongos pertenecientes a los asco-deuteromycetes. Estos compuestos fueron: poliestireno, polivinilacetato, poliacrilonitrito, policaprolactona, polimetacrilato de metilo, polivinilcloruro, acetato de celulosa y polietileno. Solo la policaprolactona y el polivinilacetato fueron utilizados por los 2 grupos de hongos en estudio, en especial por cepas de aspergillus, chaetomiun, cladosporium, fusarium, penicillium y scopulariopsis. La policaprolactona fue el polímero más utilizado entre ph 6.5 a 8. Las diferentes especies pertenecientes a los géneros aspergillus y fusarium, presentaron la mayor actividad en la utilización de estos compusetos
