FERMENTATION & ZERO POLLUTION : AN INTEGRATED SYSTEM FOR ETHYL ALCOHOL PRODUCTION • DR. FAHAD ALHABDAN, • ASSOC. PROFESSOR KING SAUD UNIVERISTY RIYADH (S.A.) • DR. S.C. BHANDARI, • PROFESSOR MPUAT (UDAIPUR) • DR. H.C. BHANDARI • CREST BIOTECH PVT. LTD. (NEW DELHI)
FERMENTATION OF VARIOUS RAW MATERIALS technology perfected – par excellence • CANE MOLASSES : C MOLASSES B HEAVY MOLASSES A HEAVY MOLASSES • CANE JUICE • SWEET SORGHUM : JUICE, SYRUP • STARCH / GRAIN : RICE, MAIZE, SORGHUM, BAJARA, WHEAT *, RAGI • SWEET POTATO • POTATO
CREST YEAST STRAIN & INTEGRATED FERMENTATION • FERMENT SUGAR : MOLASSES, CANE JUICE, SWEET SORGHUM JUICE, GRAIN, STARCH • FASTER FERMENTATION : 12 – 15 HOURS (MOLASSES / JUICE) 40 – 45 HOURS (GRAIN / STARCH) • TEMPERATURE TOLERANT : 380 C – 410 C. • HIGH ALCOHOL TOLERANCE : 9.5 – 12% V/V (MOLASSES/ JUICE) : 12 – 17 % V/V (GRAIN) • HIGH SOLIDS TOLERANCE : 25 – 35 % SOLIDS. • STRESS TOLERANT : VARIABLE RAW MATERIALS, INFECTIONS, CHEMICALS

TREATEMENT OF DISTILLERY EFFLUENT IN 1979 WE PUBLISHED A PAPER CONCLUDING : “ BIOMETHANATION OR WITHOUT BIOMETHANATION FOLLOWED BY EVAPORATION & CONCENTRATION WILL BE SUITABLE SYSTEM TO BALANCE THE ENERGY REQUIREMENT AND ZERO POLLUTION. STAI 1979. G65-72” IN THE NEAR FUTURE THIS MAY BE RIGHT APPROACH.
