ABSTRACT
Recognizing and using of isolated phytase in the soil microorganisms are paramount importance to produce the Phytase enzyme utilized commercially in different industries. This study was conducted to recognize different bacillus j species which are Phytase producers and detection of the gene that can produce this enzyme. Soil samples were gathered through different parts of mountainous areas. The early isolation of bacillus was carried out in Bacillus Medium Agar. After isolating the bacteria and genome extraction, the responsible gene of enzyme producer recognized and amplified by PCR method. The size of this protein and the optimal production situation in supplemental exploitation such as SDS-PAGE and the enzymatic activity of its size were evaluated. Of 40 samples, one bacterium secreting Phytase enzyme was isolated. This bacterium was sequenced and recognized Bacillus Sobtlis species that is classified in STR Genus. The size of protein phytase produced by this gene was about 45 KD and the enzyme activity at 55 degrees was measured about 5.65 in wavelength of 415 I NM. The phytase gene with the size of 1200 bp was propagated. the microorganisms, in natural conditions, produce Phytase enzyme in limited amount and with the quality appropriate to microorganisms. Thus, isolating the bacilli producing Phytase enzyme and purifying this protein are highly significant
ABSTRACT
Medical plants entail numerous therapeutic capabilities due to their antimicrobial activities. During the present study, the antimicrobial activity of aqueous and methanol extracts of Heracoleum Persicum was determined in vitro. We have gathered the aforementioned plant from heights of Ashkour near Tonkabon. The antimicrobial activity of aqueous and methanol extracts was determined against 14 bacterial and 2 fungal specimens according to the disc diffusion, MIC [minimal inhibitory concentration], and MBC [maximum bactericidal concentration]. The aqueous extract of Heracoleum Persicum failed to show antimicrobial activity, however, the methanol extract was effective against bacillus, streptococcous, enterococcous and nocardia. The methanol extract of Heracoleum Persicum has antibacterial activity. Further studies are strongly recommended to find out the possible therapeutic capability of this plant in infectious diseases
