isolation and characterization of xylanase producing strain of bacillus cereus from soil

Isolation and Identification of an Alkaline Protease Producing Bacillus from Soil

Characterization of an a-Amylase with Broad Temperature Activity from an Acid-Neutralizing Bacillus cereus Strain

Bacillus sp. GUF8, isolated from acidic soil samples of a tea farm was identified as Bacillus cereus, based on 16S rDNA sequencing and standard bacterial identification methods. Following optimization of enzyme production, the resulting α-amylase was purified by acetone precipitation and ion exchange chromatography. Consequently, thermostability and kinetic parameters of the purified enzyme wer...

isolation and identification of a new bacillus cereus strain and characterization of its neopullulanase

identification and use of more efficient enzymes in the food and pharmaceutical industries is the focus of many researchers. the aim of this study was to search for a new bacterial strain capable of producing high levels of pullulanase applicable to biotechnology, the starch bioprocessing and food industries. a new pullulan hydrolyzing bacillus strain was isolated and designated sdk2. morpholog...

Isolation and Characterization of Protease Producing Bacillus Species from Soil of Dairy Industry

Microbial enzymes are often more useful than enzymes derived from plants or animals because of are more stable than their corresponding plant and animal enzymes and their production is more convenient and safer (Wiseman, 1987). Only about 2% of the world’s microorganisms have been tested as enzyme sources. Microbial proteases are degradative enzymes, which catalyze the total hydrolysis of prote...

Isolation and characterization of amylase producing Bacillus spp. from selected soil sample

Amylases are among the most important enzymes and are of great significance in present day industry. Starch degrading bacteria are most important for industries such as food, fermentation, textile and paper. Amylase is a hydrolytic enzyme and in recent years, interest in its microbial production has increased dramatically due to its wide spread use in food, textile, baking and detergent industr...

Isolation and Partial Characterization of Amylase Producing Bacillus sp. from Soil

Isolated Bacillus strains BA1 and BA2 were a good source of amylase as they also showed high amylolytic activity. Both showed a clear zone on starch agar plate of 4.0 & 4.2mm in diameter respectively. The strain BA1 and BA2 produce amount of amylolytic enzyme 0.908μ/ml and 0.802μ/ml after the incubation of 24 hours at 37±2 0 C respectively. As the time of incubation increase the amylolytic acti...
