Scanning electron microscopy and Fourier transmission analysis of polyhydroxyalkanoates isolated from bacteria species from abattoir in Ota, Nigeria

摘要

This study reports production of polyhydroxyalkanoates (PHA) from microbial species obtained from abattoir by altering different carbon source (acetate and molasses) in minimal salt medium. The isolates were characterized by understanding their physiological responses to biochemical tests, optical microscopy examination and comparison to standard reference organisms. They were presumably species ofLactobacillus, Bacillus, Corynebacterium, ArthrobacterandRhodococcus.The PHA products from these isolates were confirmed to be of plastic origin using the Fourier transmission analysis and the microstructure analysis elucidated by the scanning electron microscopy coupled with electron dispersive spectra. The sourcing of this resource (PHA) from bacteria species domiciled in the high organic environment could provide amazing metabolic machinery that could create a cost effective means for PHA production.
