==Biodegradation==

Firmicutes and proteobacteria can degrade PHB. ''Bacillus'', ''Pseudomonas'' and ''Streptomyces'' species can degrade PHB. ''[[Pseudomonas lemoigne]]'', [[Comamonas|''Comamonas'' sp.]] ''[[Acidovorax faecalis]]'', ''[[Aspergillus fumigatus]]'' and ''[[Variovorax paradoxus]]'' are soil microbes capable of degradation. ''[[Alcaligenes faecalis]]'', ''[[Pseudomonas]]'', and ''[[Illyobacter delafieldi]]'', are obtained from anaerobic sludge. ''[[Comamonas testosteroni]]'' and ''[[Pseudomonas stutzeri]]'' were obtained from sea water. Few of these are capable of degrading at higher temperatures; notably excepting thermophilic [[Streptomyces|''Streptomyces'' sp.]] and a thermophilic strain of [[Aspergillus|''Aspergillus'' sp.]]<ref>{{cite journal |doi=10.3390/ijms10093722 |pmid=19865515 |pmc=2769161 |title=Biodegradability of Plastics |journal=International Journal of Molecular Sciences |volume=10 |issue=9 |pages=3722–42 |year=2009 |last1=Tokiwa |first1=Yutaka |last2=Calabia |first2=Buenaventurada P. |last3=Ugwu |first3=Charles U. |last4=Aiba |first4=Seiichi |doi-access=free }}</ref>
