Agricultural residues rich in carbohydrates can be
utilized in fermentation proceses to produce microbial
protein which in turn can be used to upgrade both human and
animal feeds. Studies to determine the factors influencing
cell biomass production with Candida sp. using citrus
fruit wastes showed that the test strain was capable of
meeting its amino acid requirements in culture when supplied
with inorganic nitrogen sources. The organism was capable of
growth at 37°C.
Supplementation of media with 0 – 15% and 0 - 6% w/v
combination of dextrose and ammonium nitrate, respectively,
resulted in optimal growth at a pH of 4.6 (optimum pH) after
6.0 h. However, supplementation with phosphorus was not a
critical condition for growth.
