Abstract
The methanotrophic strain Methylocystis sp. GB 25 DSM 7674 is able to accumulate Poly-beta-hydroxybutyrate (PHB) in a short non-sterile proc ess. The PHB content of biomass was up to 51%; effectivity was highest during the first 5 h of fermentation. The PHB yield relative to consu med methane was estimated at 0.54 g PHB/g CH4. The PHB produced is of a very high quality, i.e. it has a high molecular weight of up to 2.3 MDa. (C) 1998 Elsevier Science Limited. All rights reserved.
