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...

متن کاملChitinolytic activity of endophytic Streptomyces and potential for biocontrol.
AIMS Biological sources for the control of plant pathogenic fungi remain an important objective for sustainable agricultural practices. Actinomycetes are used extensively in the pharmaceutical industry and agriculture owing to their great diversity in enzyme production. In the present study, therefore, we evaluated chitinase production by endophytic actinomycetes and the potential of this for c...
متن کاملAntioxidant and DNA Damage Protecting Activity of Exopolysaccharides from the Endophytic Bacterium Bacillus cereus SZ1.
An endophytic bacterium was isolated from the Chinese medicinal plant Artemisia annua L. The phylogenetic and physiological characterization indicated that the isolate, strain SZ-1, was Bacillus cereus. The endophyte could produce an exopolysaccharide (EPS) at 46 mg/L. The 1,1-diphenyl-2-picrylhydracyl (DPPH) radical scavenging activity of the EPS reached more than 50% at 3-5 mg/mL. The EPS was...
متن کاملBacillus cereus in probiotic 11 PROPERTIES OF THE BACILLUS CEREUS STRAIN USED IN PROBIOTIC CenBiot
Bacillus cereus CenBiot fulfilled the requirements to be used as probiotic. The spores showed D 80 of 14 hs, inhibited Escherichia coli and Yersinia pseudotuberculosis after 24 hs in associative culture, were innocuous for suckling and adult mice and were not inhibited by antibiotics at low concentrations.
