Read this article to learn about the applications of animal cell cultures. There is a widespread concern that extensive use of animals for laboratory experiments is not morally and ethically justifiable. Animal welfare group’s world over are increasingly criticising the use of animals. Some research workers these days prefer to utilize animal cell cultures wherever possible for various studies. The [...]
The metals can be recovered by the microorganisms by two processes: (1) Bioleaching and (2) Bio-Sorption! Soil microorganisms are very closely involved as catalytic agents in many geological processes. These include mineral formation, mineral degradation, sedimentation and geochemical cycling. In recent years, a new discipline of mineral science namely bio-hydrometallurgy or microbial mining (mining with microbes) is rapidly growing. Broadly [...]
This article provides a study-note on polyhydroxyalkanoates (PHA) Polyhydroxyalkanoates (PHA) are intracellular carbon and energy storage compounds, produced by many microorganisms. They are biodegradable polymers, and are elastic in nature depending on the polymer composition. PHA are well suited for the synthesis of plastics, the biodegradable packing materials. The conventional plastics, made from coal or oil, are not biodegradable. They [...]
