Solid state fermentation (SSF) is a technology which is used for cultivation and production of micro-organisms onto a solid surface in presence of very less or no free water. The solid substrate used in SSF resembles the natural habitat of some of the microbes. The substrate which are used in this technology are mostly of two types, one is nutritional substrate and other is inert material. In case of natural substrates, the substrate itself provides the required nutrients for growth and development of the microbes. Commonly used substrate are cereal husk, oil cakes, residual biomass generated in agriculture sector, etc. Inert materials are the one which provides supports for the microbial adherence on its surface. The inert materials have to be provided with additional source of nutrients.some of the commonly used inert materials are silica, hydrated magnesium silicate salts like Talc, Polyurathrane foam, etc.

Does your compost pile stink?Growing population and rapid urbanization has led to the accelerated generation of solid waste in developing countries. Treating this huge load of solid waste generated is not always feasible to the municipalities due to numerous economic and organizational constraints. This leads to accumulation of solid waste in the dumping yards which may end up being burned. Landfills may result in contamination of ground water resources while burning may cause air pollution. Numerous other problems like infestation by insects and rodents may also be associated with these methods of garbage disposal.

Compost is nature’s own way of recycling organic waste materials into a rich soil containing humus that benefits nature by enhancing soil quality. Though the process of composting may naturally take place in the environment, it may depend on numerous factors such as quality of waste, the climate, the abundance of biodegraders and most importantly the type of microbial population that dominates the entire process of composting.
