Mucor indicus, one of the most important strains of zygomycetes fungi, has been the subject of several studies since a couple of hundred years ago. This fungus, regarded as a non-pathogenic dimorphic microorganism, is used for production of several beers and foods. Morphology of the fungus can be manipulated and well controlled by changing a number of parameters. Furthermore, M. indicus can grow on a variety of substrates including lignocellulosic hydrolysates which are mixtures of hexoses, pentoses, and different severe fermentation inhibitors. Indeed, high yield ethanol production is among the most important features of this strain. Presence of considerable amounts of chitosan in the cell wall is another important aspect of the fungus. Besides production of ethanol and chitosan, the biomass of this fungus has shown a great potential to be used as a rich nutritional source, e.g. fish feed. The fungus is also among the oleaginous fungi and produces high amounts of polyunsaturated fatty acids particularly γ-linolenic acid. Furthermore, the biomass autolysate has a high potential for yeast extract replacement in fermentation by the fungus. Additionally, the strain has shown promising results in heavy metal removal from wastewaters. This review discusses different aspects of biology and industrial application perspectives of M. indicus. Furthermore, open areas for the future basic and applied levels of research are also presented.
