Production and characterization of PHB-HV copolymer by Bacillus thuringiensis isolated from Eisenia foetida.

Polyhydroxyalkanoates (PHAs) are one of the most important biopolyesters produced by vast number of microorganisms that exist in the environment. PHAs gained much attention due to its inherent biodegradable and biocompatible ability along with its physicochemical properties, which are similar to those of conventional petroleum-based plastics. In the present study, PHA producing bacterial strains was isolated from earthworm.

Immunostimulation by poly-β hydroxybutyrate-hydroxyvalerate (PHB-HV) from Bacillus thuringiensis in Oreochromis mossambicus.

The present study was designed to test the immunostimulatory efficacy of poly-β hydroxybutyrate-hydroxyvalerate (PHB-HV) extracted from Bacillus thuringiensis B.t.A102 on the immune system of Oreochromis mossambicus.

Phenotypic and genotypic characterization of B.t.LDC-391 strain that produce cytocidal proteins against human cancer cells.

An indigenous Bacillus thuringiensis strain B.t.LDC-391 producing cytocidal proteins against human colon cancer cell line, HCT-116, was subjected to phenotypic and genotypic characterization to evaluate its relatedness to B.
