Microbes And Food

Microbes And Food- Applications of microbes to food, energy, industry and environment are interrelated in most situations. To cite an example, degradation of urban, municipal and industrial wastes by using a suitable (may be a tailored, genetically-engineered) strain of a microorganism should result into (i) dis­posal of pollutant, (ii) biotransformation of a waste- into a byproduct, suitable for consumption as food (conversion of agricultural waste into single cell protein is an example) and (iii) production of energy during such conversions. Therefore it is a three-way beneficial process carried out by a microbe.

Several yeasts, Saccharomyces, Candida, Torulopsis can be grown on waste materials, recycling them into food. Crude petroleum products are converted to SCP by Methylophilus methylotrophus. Cattle dung is fermented by methanogenic bacteria to biogas, an ideal biofuel in rural areas. Mushroom cultivation is good example of SCP where agricultural waste is recycled into food (SCP) and the left over residue used as organic manure.
