Abstract
Whey, a by-product in manufacture of coagulated dairy products, poses serious problems
due to its very high BOD and COD. Its utilization and/or disposal is limited by low solids
content. However, whey may be used for industrial purposes, if appropriate avenues are
explored based on its valuable nutrients contents. The development of simple, cheaper and
commercially viable approaches for utilization of whey will solved dual purpose of
eliminating wastage of very valuable milk solids and environmental preventing pollution.
One of the possibilities appears to be production of Lactic acid cultures using whey as a
media. Keeping this idea as a central goal, study was undertaken to develop whey based
medium for biomass production of lactic acid cultures (cultures (Lb. helveticus MTCC
5463, Streptococcus thermophilus MTCC 5461, Leuconostoc mesenteroides and
Lactococcus lactis)). The study was phased out as screening of different types of whey for
suitability, examination of effect of various pre-treatments of whey, assessment of effect
of nutrient supplementation, comparison of the developed whey based medium with the
commercially available traditional media, scaling up the process to a pilot scale production
and evaluation of the performance of biomass as starter culture for preparation of selected
fermented dairy products
