Preferably, the steady state conditions are maintained in the main fermentation stage by one or more of feeding of organic carbon sources; controlling glucose and/or total reducing sugar content; feeding of organic nitrogen sources; controlling pH; controlling foam level; controlling the mass of the fermentation broth by withdrawals and feedings; and, controlling the dissolved oxygen level.

  • Patent number: 6465228
    Abstract: A levodione reductase having the following physical properties is provided: molecular weight: from about 142,000 to about 155,000±10,000 (consisting of four homologous subunits having a molecular weight of 36,000±5,000); co-factor: nicotinamide adenine dinucleotide (AND/NADH); substrate specificity: active on levodione; optimum temperature: about 15° C. to about 20° C. at pH 7.0; optimum pH: 7.5; and activator: K+, Cs+, Rb+, Na+ and NH4+. The levodione reductase according to the present invention produces actinol, an important intermediate for the production of zeaxanthin, from levodione. This enzyme may be produced from a microorganism belonging to the genus Corynebacterium, preferably the microorganism Corynebacterium aquaticum AKU 611 (FERM BP-6448) or a functional equivalent, subculture, mutant or variant thereof.

  • Publication number: 20020137155
    Abstract: The present invention describes new and distinct strains of higher Basidiomycetes mushrooms, and a process for growing them in submerged culture. Specifically, the new strains of species of the genus Pleurotus offer superior yields of mushroom biomass and concentrations of biologically active compounds, for example, cholesterol-lowering compounds, lectins, proteins, essential amino acids, vitamins or polysaccharides. The process includes use of defined media and a simple one-step procedure of separating the lovastatin-containing nutriceuticals from culture broth.
