This study describes the physical stability and optimization of nutrient components for an extracellular protease produced by Bacillus strains isolated from fruits and vegetable waste, Lucknow, India. The isolated proteases could hydrolyze various native proteinaceous substrates such as bovine serum albumin, casein, skim milk, but not the gelatin. The strain JX416854 and isolate 10 yielded maxi...

Otomycosis is a fungal infection of the ear predominantly caused by Candida and Aspergillus spp. The possible virulence factors of Candida spp. are enzymes, such as proteases, phospholipases, phosphatases and esterase. According to our knowledge, protease production in Candida strains isolated from patients with otomycosis has not been investigated. The present study was aimed at determining in...

  Abstract   Background: The interest in using bacteria as anti- cancer therapeutic agents dates back to the end of the19th century. Some bacteria like Salmonella and Listeria replicate effectively inside malignant cell lines and suppress their growth. The bacterium Streptococcus pyogenes has become medically famous as a flesh-eating pathogen since mid-1980s. It is the causative agent of a life...

alkaline crude enzymes from the viscera of the tunisian barbel (barbus callensis) were extracted and characterized. proteolytic crude extract from barbel viscera was active and stable in alkaline solution. the optimum ph and temperature were 11.0 and 55 °c, respectively, using casein as a substrate. the crude alkaline protease was extremely stable in the ph range of 5.0-12.0. zymography activit...

The antifungal effect and mucolytic activity of a newly screened biocontrol strain Chaetomium subaffine LB-1 were researched in this study. results found that has good effects on the test plant pathogenic fungi Botrytis cinerea Pers. ex Fr., Fusarium oxysporum f. sp. cucumerinum Owen Alternaria solani (Ellis & Martin) Sorauer dual culture assay, with inhibition rates 61.39, 50.34 51.22%, respec...

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection that causes COVID-19 disease is still a major public health concern around the world. main protease encoded by SARS-CoV-2 promising target for therapeutic development since it plays crucial role in virus’s life cycle. Repurposing known bioactive molecules an effective strategy to fast-track delivery of hits and leads dru...

Actinobacteria have long been known to the ability produce bioactive compounds secondary metabolites. rhizosphere Jack were expected beneficial metabolite with antibacterial, activity, enzymes. A total 34...

Soybean meal (SBM) is widely used in shrimp feed agro-industry as a fish (FM) replacement. However, high levels of SBM may compromise animal health result nutrient imbalance. This study aimed to investigate the effects enzyme combination (a mixture 6-phytase, serine protease, and endo-1,3(4)-β-glucanase) functional immunostimulant brewer's yeast, nucleotides, vitamin C, E) improving overall Pac...
