The effect of fortification of concentrated whey with 0.5% inorganic nitrogen viz. NH4Cl, (NH4)2SO4, NaNO3 and urea, organic nitrogen viz. tryptone, tryptose, peptone and yeast extract and 0.1% metal ions viz. K2HPO4, MgSO4 and FeSO4, on growth stimulation of Kluyveromyces marxianus subsp. marxianus NRRL Y-665, NRRL Y-1195, NRRL Y-2415 and Kluyveromyces marxianus subsp. lactis NRRL Y-1193 were studied. Supplementation with 0.5% (NH4)2SO4, peptone, yeast extract or 0.1% K2HPO4 individually increased the biomass production by 8-20%, 17-25%, 13-14% and 14-17%, respectively. Addition of 0.5% each of (NH4)2SO4, peptone, yeast extract and 0.1% K2HPO4 together is recommended to increase the biomass production by 81-98% for commercial production of single cell protein.
