Production of Poly-3-Hydroxyalkanhoate by Haloarcular sp. EH-1

Haloarcular sp. EH-1으로부터 생분해성 Poly-3-Hydroxyalkanoate의 생산

  • Published : 1999.12.01


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$^{\circ}C$, viscosity was 1.25 ㎗/g, and molecular weight was $1.44 X 10^5.$
