Single Cell Protein Production from Rayon Pulp Mill Waste by Paecilomyces variotii

概要

論文の詳細を見る
Prehydrolysate liquor obtained from a rayon pulp mill was used as a substrate to produce single cell protein (SCP). Ten different strains of Paecilomyces variotii were locally isolated and screened for the production of SCP from prehydrolysate according to the following optimization creteria : rates and yield of biomass production, rates of substrate utilization, maximum specific growth rates and total biomass formation. The optimal SCP producer was found to be P. variotii TCRDC-M5 which gave a μmax of 0.11/h and a biomass yield of 96% of the theoretical, with 95% substrate utilization and 25 g dry wt. biomass/l in the Lab. fermentor. This resulted in a 70% reduction in the BOD of the prehydrolysate.
