The isolates were designated as PS1 to PS30. The genetic code is a set of three-nucleotide sets called codons and each three-nucleotide combination designates an amino acid, for example AUG … Each protein has its own unique amino acid sequence that is specified by the nucleotide sequence of the gene encoding this protein. The isolates were hereby referred as S 1, S 2, S 3, S 4, S 5 and S 6. For the isolation of protease producing organisms from soil the enrichment culture should be used . e.g. • An Isolate with the highest protease activity had 99% 16S rDNA similarity to Bacillus amyloliquefaciens.. B. amyloliquefaciens had good viability and stability in pellet, seawater, and simulated GIT of abalone.. Protease produced by the bacterial strain could effectively … Isolation and screening of protease producing bacteria A total of 30 bacterial isolates showing zone of proteolysis were selected from skim milk agar plates inoculated with the soil sample and all of them were confirmed for protease production on further screening by spotting on skim milk agar plates. In order to isolate the protease-producing bacteria, the samples were gathered from sea muds in the Geziwo Qinhuangdao Sea area and were diluted with sterile sea water. Thirty-one thermostable protease producing bacteria were isolated from different soil samples (Compost, hot spring and Manures) collected from various parts of north of Iran. Protease producing bacteria was isolated from marine soil sample from Marakkanam Saltern, Tamil Nadu. Ten bacteria isolated prom the GITs of hybrid abalone had the capacity to produce protease. The proteases enzyme production bacteria were screened on … For the production of protease the microorganisms are used such as bacteria and fungi. Screening of protease producing bacteria: Six isolates were selected as protease producing bacteria due to their growth on skim milk agar plate showing zone of casein hydrolysis . The isolation, characterization, and optimization of various isolates (especially of … Protease-producing bacteria was identified by clear zones of skim hydrolysis around colonies. The present study deals with isolation of protease producing bacteria from different soil samples. Proteins are assembled from amino acids using information encoded in genes. Background: Extremophiles are a hot topic in the field of biotechnology for their immense potential and applications in multiple industries. Based on their morphology, it was identified as Pseudonomonas fluorescens biovar. Bacillus subtilis Aspergillus oryzae,Penicillium roqueforti . They were screened by sub culturing repeatedly on alkaline media at pH 10 The bacteria were inoculated in gelatin agar for the production of protease enzyme. Objectives: The present review aims to sum up the potential applications of alkalophilic protease-producing bacteria and their optimized growth requirement. The current study was focused on the screening of protease enzyme producing bacteria from dairy product of cheese at Dilla University. protease producers Many bacterial isolates with special ability of protease enzyme production (proteolytic activity) were screened depending on different growth parameters such active growth on alkaline medium, active growth at high temperature, clear zone formation, etc. Protease-producing bacteria belonging to Photobacterium, Bacillus, and Vibrio were the richest cultivated protease-producing bacteria in Jiaozhou Bay marine sediments . Cheese sample was collected from Dilla town market.
