Production of α-amylase using new strain of Bacillus polymyxa isolated from sweet potato

Thermostable α-amylase from Lignocellulosic Residues Using Bacillus amyloliquefaciens

Bioconversion of wastewater from sweet potato starch production to Paenibacillus polymyxa biofertilizer for tea plants

Wastewater from the sweet potato starch industry is a large source of nutrient-rich substrates. We assessed whether this wastewater could be used to produce Paenibacillus polymyxa biofertilizer for foliar application to tea trees. Using the central composite design methods we experientially determined that the optimal culture conditions for P. polymyxa were pH, 6.5; temperature, 29.0 °C; and in...

Production and purification of a protease from an alkalophilic Bacillus sp. 2-5 strain isolated from soil

This research has focused on isolation and characterization of a strain of Bacillus <span style="font-variant: normal; font-style: normal; font-family: ArialMT...

Biosorption of Strontium from Aqueous Solution by the New Strain of Bacillus sp. Strain GT-83

An attempt was made to isolate bacterial strains capable of removing strontium biologically. In this study ten different water samples collected from Neydasht spring in the north of Iran and then the bacterial species were isolated from the water samples. The initial screening of a total of 50 bacterial isolates resulted in selection of one strain. The isolated strain showed a maximum adsorptio...

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...
