Abstract
The present investigation reports the use of Candida Haelmdonii MTCC1964, isolated from dairy industry effluents to carryout the treatment of dairy wastewaters at a bench scale fermenter. The process parameter such as inoculum size, pH, agitation and treatment time were optimized. The inoculum rate of 12.5% (v/v) and 24 h of treatment time at pH 5.5, and 30°C, with agitation rate of 150 rpm, supported the maximum BOD, (71.1%) and COD (70.0%) reductions of dairy wastewaters.
