Cyanobacterial Polyhydroxybutyrate (PHB): Screening, Optimization and Characterization
In modern life petroleum-based plastic has become indispensable due to its frequent use as an easily available and a low cost packaging and moulding material. However, its rapidly growing use is causing aquatic and terrestrial pollution. Under these circumstances, research and development for biodegradable plastic (bioplastics) is inevitable. Polyhydroxybutyrate (PHB), a type of microbial polye...
متن کاملCharacterization of -Glutamyl Hydrolase Produced by Bacillus sp. Isolated from Thai Thua-nao
-Glutamyl hydrolase with a molecular mass of 28 kDa was purified from the culture broth of Bacillus sp. isolated from Thai Thua-nao, a natto-like fermented soybean food. The purified enzyme hydrolyzed chemically synthesized oligo-L-glutamates but not oligoD-glutamates and degraded -polyglutamic acid to a hydrolyzed product of only about 20 kDa (with Dand L-glutamic acid in a ratio of 70:30), su...
متن کاملFermentation Optimization for Production of Polyhydroxybutyrate (phb) by Newly Isolated Azotobacter Vinelandii Kdp
Producing the biodegradable plastic is the most important processes nowadays because to overcome the recent issues concerning the global environment and solid waste management. The optimum conditions for PHB production are more important to enhance the production by microorganism. In the present investigation newly isolated Azotobacter vinelandii KDP culture conditions were optimized to produce...
متن کاملStudy on Activity and Stability of Proteases from Bacillus Sp. Produced by Submerged Fermentation
Objective: Investigations were carried out to isolate bacteria from saline-alkali soils and determined optimized alkaline protease activity and stability produced by a wild strain of bacillus sp. in submerged fermentation (SMF). Methods: Optimum temperature for enzyme activity in the crude extract was 40 ◦C at a pH between 8.0 and 9.0. The studies on pH stability showed that the enzyme...
متن کاملBatch Kinetics and Modeling of Alkaline Protease Production by Isolated Bacillus sp. (RESEARCH NOTE)
The aim of this study was the use of fish waste hydrolysate (FWH) as a substrate for alkaline protease production using isolated Bacillus sp. in a batch system. Then the fermentation kinetics of enzyme production was studied. The results show that with the addition of FWH to the fermentation medium with a final concentration of 4% (optimal concentration), alkaline protease value reached a maxim...
