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 productsenDairy ChemistryDevelopmentThesis
