PLANT-ORIGIN LIQUID WASTE - A RESOURCE FOR SINGLE-CELL PROTEIN-PRODUCTION BY YEAST

Leaf protein was separated by heat coagulation (80 degrees C) from lea f juices of four cruciferous plants: turnip (Brassica campestris L.), mustard (Brassica nigra Koch.), radish (Raphanus sativus L.) and cauli flower (Brassica oleracea L. var botrytis). Three yeasts, Saccharomyce s cerevisiae, Torula utilis and Candida lipolytica, were grown in depr oteinized leaf juices (DW) of these plants. The yeast cells produced i n these wheys were found to be rich in protein and vitamins. The chemi cal oxygen demand (COD) and biological oxygen demand (BOD) values of D W samples were reduced significantly by the growth of yeasts. Copyrigh t (C) 1996 Elsevier Science Ltd.
