Scale Up Studies for Polyhydroxyalkanoate Production by a Strain with Industrial Potential.

Polyhydroxyalkanoates (PHA) are synthesized by bacteria under unfavourable growth conditions like excess of carbon over nitrogen, coupled with oxygen limitation. The PHA polymers of microbial origin are diverse in chemical composition and material properties. A bioprocess for PHA production by indigenously isolated MTCC 12841 was devised and optimized at a laboratory fermentor scale.

Statistical optimization for enhanced yields of probiotic and its phage resistant mutants followed by kinetic modelling of the process.

Probiotics are microorganisms which when administered in adequate amounts confer health benefits to the host. A leading pharmaceutical company producing as a probiotic was facing the problem of recurring phage attacks. Two mutants viz.

Probiotics, prebiotics and synbiotics- a review.

The health benefits imparted by probiotics and prebiotics as well as synbiotics have been the subject of extensive research in the past few decades. These food supplements termed as functional foods have been demonstrated to alter, modify and reinstate the pre-existing intestinal flora. They also facilitate smooth functions of the intestinal environment.
