Abstract
|
|
|
|
The extremely halophilic archaebacterium Haloarcular sp. EH-1 was isolated from solar salts. Haloarcular sp. EH-1 accumulated poly(3-hydroxyalkanoate) (PHA) as intracellular granules. PHA production in batch culture have been studied. The PHA was identified as poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid) (PHB/HV) of 3-hydroxybutyric acid and 3-hydroxyvaleric acid by the analysis of GC, IR and NMR. The melting temperature of PHB/HV was 152.46℃, viscosity was 1.25 ㎗/g, and molecular weight was 1.44×105.
