Yield and quality of agars in selected members of Gelidiales and Gracilariales

Abstract :

Polyhydroxybutyrate (PHB) is a very basic polymer which is accumulated as energy reserve material by many bacteria. It is water soluble, biocompatible and non-toxic. A study was conducted to isolate and evaluate the PHB producing soil bacteria. A total number of 7 different bacterial genera were isolated and the amounts of PHB were estimated. Bacillus subtilis was the most efficient producer among the test isolates. Further, 25 isolates of Bacillus sp. were isolated and 18 of which were identified to be Bacillus subtilis. Among them, two isolates (isolate nos. 15 & 25) were confirmed to accumulate maximum PHB and Bacillus subtilis isolate no. 25 produced more PHB with different sugars, organic and inorganic nitrogen sources at varying concentrations.
