Original Abstract
Millions of tons of feather, important waste product of poultry-processing industry, are disposed of annually without any further benefit. Therefore, the main aim of this work is to study biodegradation of chicken feather by selected Pseudomonas strains revealing keratinase activity and which are also capable of polyhydroxyalkanoates accumulation. Non-treated chicken feather was used as the sole carbon substrate for cultivation of bacteria Psudomonas putida KT2440 and two strains isolated from petroleum polluted areas which were identified as Pseudomonas fulva and Pseudomonas gessardii. Enzymatic activity of proteinase and keratinase was determined in cultivation media. Pseuodomonas putida demonstrated the highest degradation enzymatic activity. Further, bacterial culture grown on waste feather can be used as inoculum for the production of PHA using waste frying oil as a substrate and and octanoic acid as a precursor of MCL-PHA. In this condition, Pseudomonas gessardii creates 6 and 8 carbon PHA.
