“…More detailed physiological studies of A. curvatum were performed in a chemically defined medium by Park (Park, 1989;). This group had already been investigating microbial production of lipid and biochemical explanations of lipid synthesis in other oleaginous microorganisms (Whitworth and Ratledge, 1975;Gotham and Ratledge, 1978; Gotham and Ratledge, 1979;Ratledge, 1982 xylose and ethanol were tested for efficiency of fat production in batch and continuous systems.…”
