Abstract Ethanol from renewable resources has been of interest in recent decades as analternative fuel or oxygenated additive to current fossil fuels Bioethanol can be producedby fermentation from a variety of raw materials which contain sugars starch andlignocellulosic substances A great number of fungi are able to produce ethanol Zygomycetes are saprophytic filamentous fungi which are able to produce severalmetabolites including ethanol Among the filamentous fungi Mucor indicus formerly M rouxii showed good performances on ethanol productivity from glucose xylose and woodhydrolyzate M indicus has been shown dimorphism properties It is able to grow either inyeast like or filamentous forms Beside the production of ethanol the biomass of thisfungus contains appreciated level of chitosan which is a valuable product In the currentstudy we studied the ability of the different morphology of M indicus for ethanolproduction under aerobic and anaerobic condition from glucose fructose sucrose sugarcane molasses and sugar beet molasses This fungus showed the ability to produceethanol from glucose and fructose but it can not ferment sucrose Therefore we examinedthe fermentation of enzymatic inverted sucrose and the molasses The yield of productionof ethanol glycerol biomass and chitosan on glucose fructose sugarcane molasses sugarbeet molasses inverted sucrose inverted sugarcane molasses and inverted sugar beetmolasses were examined The maximum yield of ethanol and glycerol were obtained underanaerobic condition and the maximum yield of biomass was obtained under aerobiccondition where as the yield of ethanol from yeast like morphology is the same asmycelial morphology and the yield of biomass of yeast like is more than mycelia On theother hand the yield of chitosan obtained from mycelia is more than yeast like Thesugarcane and sugar beet molasses and their sucrose inverted form are good sources forbiomass and chitosan production where as the enzymatic sucrose inverted sugarcane andsugar beet molasses are good alternative for production of ethanol
