Bio remediation employs biological agents to render hazardous wastes to non-hazardous or less hazardous wastes. Some fungi even as dead biomass trap metallic cations in aqueous solutions. This is due to their special wall composition. Many fermentation industries produce fungal biomass of an unwanted byproduct which can be used for this purpose.the toxic materials remain in vapor, liquid, or solid phases, therefore, bio remediation technology varies accordingly whether the waste materials involved is in its natural contemporary furniture setting or its natural settings or removed and transported into bio reactor. On the basis of removal and transportation of wastes for treatment, it is divided into two types .They are in-situ remediation and ex-situ remediation. If we use this method for cleaning environment than our world will be devoid of pollution and its effect.

Bio remediation is the use of living organisms to degrade environmental pollutants or prevent pollution. It is a technology for removing pollutants from the environment, restoring contaminated sites and preventing future pollution. However, it has global, regional and local application. The basis of bio remediation is the enormous natural capacity of micro organisms to degrade organic compounds. Bio remediation is the Cosmetic Surgery microbial cleanup approach microbes can acclimatize themselves to toxic wastes and new resistant strains develop naturally. But if microbial physiologists, biochemists, genetics and ecologist join hands with chemical engineers, efficacy, efficiency, economy, and environmental safety can be generated in the use of microbes for environmental protection. The microbe referred to as GS-15 has been found by an American microbiologist who can eat up uranium from wastes of a nuclear weapon manufacturing plant.GS-15 microbes in bio reactor convert uranium in water into particles that precipitate and settle to the bottom. Collection and disposal then become easier. The organisms grow overnight. It can be useful for waste water treatment.

Dried biomass of a single species of microbe that can be used as a protein source in the diet, is known as single cell protein (SCP).the dried biomass of some microbes is rich in nutritionally valuable proteins, vitamins, minerals, and it does not contains any toxic substances. It is used as a protein source in human diet and animals feed. Bio masses of certain algae, some fungi, and some bacteria are used as a single cell protein. For the first time, during the First World War, in Germany biomass of Saccharomyces cerevisae was produced in large scales and consumed as a protein source. Since then many microbes have been invented for their nutritive values and tummy tuck consumed as a protein source. Before recommending an organism for SCP, the chemical composition of dried biomass, toxicity, nutritional value, energy value, digestibility, aceceptibility and safeness should be tested with laboratory animals. If the biomass has any toxin then it is hazardous to the laboratory animal. It is not considered for SCP

Biochips made up of various biological materials are looked for as a solution to miniaturize the computer by replacing silicon chips with biochips. Biomolecular computers thus made promise to be ten to thousand times smaller than the computers. Presently, research in biomolecular computing is concerned with isolating proteins that provide signal transport memory bank foreclosure switching and logic functions. The basic idea behind biochip research is to insert semi-conducting molecules into the protein frame work and fix the whole on to a protein support and they can assemble themselves in to a three dimensional structure.
