Abstract

This Dissertation / Report is the outcome of investigation carried out by the creator(s) / author(s) at the department/division of Central Food Technological Research Institute (CFTRI), Mysore mentioned below in this page.

Item Type: Student Project Report
Additional Information: <p align="justify">The present study was aimed to study the PHA production by the native bacterial isolate. Based on the biochemical tests and microscopic observation, the isolate obtained was tentatively identified as Micrococcus sp. Interestingly this culture also producing red colour pigment.Optimization studies were carried out to improve the production of PHA by the isolate. The parameters selected were source of carbon, rate of inoculum, effect of initial pH, effect of fermentation temperature and effect of aeration. It was found that all these parameters have significant effect on the production of the PHA by the isolate. Of the carbon sources tested sucrose has yielded more PHA (20.4% of the dry weight of the biomass). Although glucose has resulted in more biomass, the rate of PHA production was very poor with only 8.46% of the dry weight of the biomass. Lactose and fructose have also supported good growth and PHA production.</p>
