“…Using fermentation technology, the maximum PHB that can be accumulated by heterotrophic bacteria amounts to up to 80% of the dry cell weight (dcw; Reddy et al, 2003). To have a clear picture of bacterial PHA production, readers are referred to Lafferty, Korsatko, and Korsatko (1988); Anderson and Dawes (1990); ; Fuller and Lenz (1990); Lee (1996); Sasikala (1996); Steinbüchel (1996) ;Braunegg, Gilles, and Klaus, (1998); Lee, Choi, and Wong (1999); Sudesh, Abe, and Doi (2000); Ishizaki, Tanaka, and Taga (2001); Serafim et al (2001), Reddy et al (2003), Khanna and Srivastava (2005), Lenz and Marchessault (2005), Valappil et al (2007), Suriyamongkol et al (2007), Chen (2009), Keshavarz and Roy (2010) and Sudesh et al (2011). Despite being under investigation for such a long time, large-scale PHA production is still to be optimized.…”
