EFFECT OF CULTURE MEDIA ON THE POLYHYDROXYBUTYRATE PRODUCTION OF SPIRULINA SP.

Abstract

In reaction to the environmental issues caused by plastics of petrochemical beginning, a decrease in utilization of these materials and their substitution by biodegradable polymers has been sought. Polyhydroxybutyrate (PHB), a biopolymer of biological beginning that has a place to the polyhydroxyalkanoates (PHAs), is comparable to polypropylene in terms of its mechanical properties, thermo degradability and dissolving temperature. Different microorganisms, including cyanobacteria, can synthesize this biopolymer. The objective of this study was to stimulate biopolymer amalgamation by Spirulina sp., Spirulina was developed under distinctive carbon sources. At first, the growth was conducted with Spirulina sp., and at that point neem cake and groundnut cake was utilized as a carbon source. In different nutrient mediums, Spirulina appeared the most extreme concentration of biopolymers. The PHB were evaluated at 235nm by utilizing UV spectrophotometer. The pure frame of PHB powder was collected.
