One of our major scientific and technological advances has been in the area of harnessing the activities of microorganisms. For years it has been known that numerous kinds of yeast, fungi, and bacteria have a direct relation, either favorable or unfavorable, to operations such as brewing, wine making, and cheese making. One of the most recent applications of microorganism is in the search for additional sources of protein (SCP). These have emerged from small-scale or family arts to the present industrial scale. Only in the past few decades, the advantage of exploiting microbial activity has...

Bioremediation - one of the environmental clean up methodologies is well-known for its application in creosote contaminated soil systems. An attempt was made at our end to use this technology for liquid systems, specifically to a combined industrial effluent. It is a complex mixture of effluents discharged into a typical common effluent treatment plant by thirty five different industrial units of an industrial estate at Hyderabad. Broadly, the biosorption studies included reduction/removal of metals and biodegradation of complex organic compounds present in the combined industrial effluents...
