V. Yellore et A. Desai, PRODUCTION OF POLY-3-HYDROXYBUTYRATE FROM LACTOSE AND WHEY BY METHYLOBACTERIUM SP. ZP24, Letters in applied microbiology, 26(6), 1998, pp. 391-394
Methylobacterium sp. ZP24, isolated from a local pond, is able to grow
in a medium containing 12 g l(-1) lactose as a sole source of carbon,
giving 5.25 g l(-1) biomass yield and poly-3-hydroxybutyrate (PHB) up
to 59% of its dry weight in 40 h. The isolate was also able to utiliz
e cheese whey and produce 1.1 g l(-1) PHB. Addition of ammonium sulpha
te increased the production of PHB from whey 2.5-fold. The potential o
f Methylobacterium sp. ZP24 in PHB production from cheese whey is disc
ussed.
