Utilization of Industrial Waste for the Production of Poly-Beta-Hydroxy Butyrate (Phb) by Alcaligenes eutrophus

Alcaligenes eutrophus was collected from MTCC bank and purity was checked according to the guidelines of Bergey's manual of bacteriology. The PHB production ability of the culture was tested by "Granular stains method". The test organism was grown in synthetic and various industrial waste based medium (Molasses, seasame oil waste) at different concentration (10%, 20%, 30% and 40%).The PHB producer grown in synthetic and various industrial waste based medium and PHB was extracte and estimated by using UV spectrophotometer. The pure form of PHB powder was collected and studied by Infrared analysis. In the present study, the high PHB production was seen in Alcaligenes eutrophus grown in 40% concentration of seasame oil waste when compared with other substrate and synthetic medium. The present study concludes that the seasame oil waste based medium and Alcaligenes eutrophus used for PHB production in large scale that minimize the cost of the product. Thus we can minimize the use of petroleum-derived plastics and by which we can live in a plastic pollution free earth.
