BIOMASS PRODUCTION AND TREATMENT OF KITCHEN WASTE WATER WITH NOSTOC MUSCORUM-A POTENTIAL BIOFERTILIZER

Abstract

Kitchen waste water emerging from Tirumala hills, a world famous piligrim centre was used as a source of nutrients for cultivation of Nostoc muscorum. A complete randomized design (CRD) was created for the experiment which was performed on BG-11 medium, 100% kitchen waste water (100% KW) and 75% kitchen waste water (75% KW). The physicochemical properties of kitchen waste water and the yield of biomass were determined from the cultures harvested every three days for a period of 15 days. After cultivation the kitchen waste water met the standards of safe discharge in India. The organisms could able to remove maximum of 98% of contaminants during its growth in waste water. The highest production of biomass was achieved in BG-11 medium followed by 100% KW and 75% KW.
