Influence of Altered NADH Metabolic Pathway on the Respiratory-deficient Mutant of Rhizopus oryzae and its L-lactate Production.

abstract：:Growth kinetics and red pigment production of Monascus purpureus CCT 3802 was studied. A reproducible inoculum with extremely dispersed hyphae for bioreactor runs was obtained through a two-step cultivation in a shaker. First, the spores were cultivated in a complex medium rendering a suspension of vegetative cells. I...
