Comparison of the alpha-amylase of Bacillus subtilis and Bacillus amyloliquefaciens.

Bacillus Amyloliquefaciens Alpha-amylase Inhibition by Organic Solvents: A Study on Methanol, Ethanol and Propanol

Alpha-amylase is widely used as an industrial enzyme, and a therapeutic target for which inhibitors are designed. Organic solvents are used to dissolve various compounds that would be studied as moderators of alpha-amylases, but they could themselves affect enzyme activity and stability. Methanol, ethanol and propanol are simple alcohols that may be commonly used to this end, and their effect h...

Unrelatedness of Bacillus amyloliquefaciens and Bacillus subtilis.

Eight strains of highly amylolytic, sporeforming bacilli (hereafter referred to as Bacillus amyloliquefaciens) were compared with respect to their taxonomic relationship to B. subtilis. The physiological-biochemical properties of these two groups of organisms showed that B. amyloliquefaciens differed from B. subtilis by their ability to grow in 10% NaCl, characteristic growth on potato plugs, i...

Thermostable α-amylase from Lignocellulosic Residues Using Bacillus amyloliquefaciens

Phylogenetic and Comparative Sequence Analysis of Thermostable Alpha Amylases of kingdom Archea, Prokaryotes and Eukaryotes

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...

Taxonomic characterization and plant colonizing abilities of some bacteria related to Bacillus amyloliquefaciens and Bacillus subtilis.

The phylogenetic relationships of 17 Bacillus strains isolated from plants and soil were determined from partial sequences of genes encoding 16S rRNA, gyraseA (gyrA) and the cheA histidine kinase. Five strains were closely related to Bacillus subtilis subsp. subtilis, three strains were more closely related to B. subtilis subsp. spizizeni and two strains were identified as B. mojavensis. The re...
