Alpha amylase family is generally defined as a group of enzymes that can hydrolyse and transglycosylase α-(1, 4) or α-(1, 6) glycosidic bonds along with the preservation of anomeric configuration. For the comparative analysis of alpha amylase family, nucleotide sequences of seven thermo stable organisms of Kingdom Archea i.e. Pyrococcus furiosus (100-105°C), Kingdom Prokaryotes i.e. Bacillus li...
the goal of this research was to isolate and identify the thermostable alkaline protease producing bacteria among several native iranian microorganisms. at the end of screening program, a bacillus subtilis bp-36 strain producing thermophilic alkaline protease was isolated from a hot spring in ardebil province. the target enzyme was purified using a one-step aqueous two-phase systems (atps) prot...
conclusions b. subtilis entrapped in beads was able to preserve its viability and produce biosurfactants as secondary metabolites. therefore, this method could be applied as a continuous culture system of biosurfactant production. methods alginate and bacterial solutions were mixed by stirring to obtain a uniform mixture and added by drops into cacl2 solution to form spherical beads. the spheri...
Azoreductases have been characterized as enzymes that can decolorize azo dyes by reducing azo groups. In this study, genes encoding proteins having homology with the azoreductase gene of Bacillus sp. OY1-2 were obtained from Bacillus subtilis ATCC6633, B. subtilis ISW1214, and Geobacillus stearotherophilus IFO13737 by polymerase chain reaction. All three genes encoded proteins with 174 amino ac...
Genome features of the Bacillus cereus group genomes (representative strains of Bacillus cereus, Bacillus anthracis and Bacillus thuringiensis sub spp. israelensis) were analyzed and compared with the Bacillus subtilis genome. A core set of 1381 protein families among the four Bacillus genomes, with an additional set of 933 families common to the B. cereus group, was identified. Differences in ...
BACKGROUND Bacillus subtilis are opportunistic, spore forming bacteria, common soil inhabitants. A resistant spore allows bacteria to endure extreme conditions of heat and desiccation in the environments promotes their survival in many instances, even in environments like hospitals. OBJECTIVES This paper purposes to find out the incidence of Bacillus subtilis from various sources at Azadi Tea...
Comparative Study for Biosurfactant Production by Using Bacillus subtilis and Pseudomonas aeruginosa
Biosurfactants are amphiphilic compounds produced by various bacteria and fungi which reduce surface and interfacial tension. Oil contaminated soil were collected from four different automobile shop in Mayiladuthurai, Tamilnadu, India. Bacillus subtilis and Pseudomonas aeruginosa were isolated and identified from these four samples and these were screened for biosurfactants production using veg...
A bacterial strain isolated from soil for its potential to control the anthracnose disease caused by Colletotrichum gloeosporioides was identified as a Bacillus subtilis. Bacillus subtilis CMB32 produced antifungal agents on M9 broth at 30degreesC. Biosurfactant lipopeptides produced by Bacillus subtilis CMB32 were precipitated by adjusting to pH 2 and extracting using chloroform/methanol, and ...
The expression of the neutral protease gene (npr) from the thermophilic Bacillus sp. BT1 strain was studied in its natural host and in mesophilic Bacillus subtilis. In the thermophilic BT1 strain, the transcription of the protease gene is initiated from its own promoter, just 5' to the gene. In contrast, in heterologous B. subtilis this thermophilic npr promoter does not function, and expressio...
Protoplasts of Bacillus larvae NRRL b-3555 and Bacillus subtilis RM125 (restrictionless, modificationless mutant) were transfected with DNA from the B. larvae bacteriophage PBL1c in the presence of polyethylene glycol. B. subtilis 168 and Bacillus popilliae NRRL B-2309M protoplasts could not be transfected with PBL1c DNA. Protoplasts of B larvae NRRL B-3555 were transformed with plasmids pC194 ...
