The production of thermostable extracellular protease by Bacillus stearothermophilus F1 was influenced by the composition of culture medium. Peptone iv derived from soybean was the best organic compound for enzyme production. Sodium nitrate, ammonium salts and amino acids as sole nitrogen sources interfered with protease formation. The addition of most carbon sources to the peptone medium faile...

The prokaryotic residents of the Tis solar saltern in the southeast of Iran on the shore of Oman Sea were investigated by the culture-dependent methods. Sequencing of the PCR-amplified fragments of 16S rRNA genes revealed that bacterial populations were related to Actinobacteria, Bacteroidetes, Balneolaeota, Firmicutes, and Proteobacteria. T...

As an important industrial enzyme, protease is widely used in feed, food and other fields. At present, the insufficient activity obtained from microorganisms cannot meet purpose of production. In this study, Bacillus amyloliquefaciens with high production was screened animal feces by plate transparent circle method. To improve protease, atmospheric room temperature plasma (ARTP) mutagenesis fir...

Background and Purpose: Today, treatment of life-threatening fungal infections, caused by Candida species, has become a major problem. In the present study, we aimed to evaluate the antifungal susceptibility patterns of different clinical Candida isolates, determine the virulence factors in multi-drug resistant (MDR) Candida species, and assess the anti-biofilm activity of Elettaria cardamomum ...

Rhizopus oligosporus was used in the present study for the production of protease enzyme under SSF. Sunflower meal was used as by-product of oil industry incorporated with organic salts was employed for the production of protease enzyme. The main purpose of the present was to study different parameters of protease productivity, its yields and to optimize basal fermentation conditions. The optim...
