Cryptocaryon irritans is an obligate parasitic ciliate protozoan that can infect various commercially important mariculture fish species and cause high lethality and economic loss. Current methods of controlling this parasite with chemicals or antibiotics are widely considered to be environmentally harmful. Piscidins with broad spectrum antibacterial, antifungal and antiviral activities were found to have potent activity against C. irritans. Little, however, has been understood about the killing mechanisms of piscidins in parasites.

The recent development in so called ‘‘green chemistry’’ shows that alternative methods of carrying out chemical harmfulness of classical reactions. Besides using less catalyst and less or without solvent, one of the most popular and interesting approaches in this field is employing the microwave energy for conducting many chemical transformations. The interaction of the matter with such kinds of electromagnetic waves results in higher speed of heating [17], much shorter reaction time and very often the higher selectivity of desired products.

Increasing public concern about the potential damage of chemical inputs in agricultural production systems has challenged industry to develop new and effective pest management and control strategies against insect pests, diseases and weeds. These new strategies must be less harmful to the environment than the current, chemical-based ones, and they must also safeguard the health of agricultural workers and consumers.

For many years, the use of chemical agents to control crop pests has been degrading the environment, bringing problems to humans and all living things. An alternative to deal with the pests is the use of biopesticides, biological agents capable of controlling these harmful organisms.

Humans are exposed to an array of both harmful and beneficial hormonally active compounds in the environment and through diet. Two such chemicals are Bisphenol A (BPA), a plasticizer, and genistein, a component of soy. Prepubertal exposure to BPA increased mammary carcinogenesis, while genistein suppressed cancer in a chemically-induced model of rodent mammary cancer.

The purpose of this study was to develop an efficient protocol for genotype independent gene transformation in cotton (Gossypium hirusutum) a worldwide commercially important fibre crop, to reduce the adverse impact of harmful chemicals used to control biotic stress. Most cotton varieties remain recalcitrant and amenable to genetic manipulation to protocols so far developed.

Chemical farming is not good for the soil health and the soil is becoming unfertile day by day. Chemical farming also harms to the environment. People's health is also deteriorating due to chemical farming product. Such farming is also causing economic loss to the farmers so the natural farming is only way to recover from this type of severe problems.

This study demonstrates that the use of organic sprays viz., FAA, EAA and Vermiwash could be used as a valuable organic liquid fertilizer for better yield from Amaranthus and also without the harmful effects of chemical fertilizers. Increase in Fish consumption results in waste production which can be reutilized to reduce the negative impact on environment.

Tomato (Solanum lycopersicum Linn) is one of the most consumed vegetables in the world and is a dietary source of vitamin, minerals, and fiber, which are important for human nutrition and health. It is extensively grown throughout the world. Sodium Azide is a chemical mutagen that has become an important tool to enhance agronomic traits of crop plants. It is being used to produce resistance in various susceptible crops to improve their yield and quality traits against harmful pathogens.

Aquatic pollution occurs due to the discharge of harmful substances, chemicals or microorganisms into water bodies i.e. a stream, river, lake, ocean, aquifer, or other body of water resulting in contamination & degradation of water quality and rendering it unsuitable for human use or the environment. Many advanced water treatment techniques are followed before discharging this polluted water into the surrounding environment. However some limitations is there. In this context, Biofilms have become the important part of biological treatment of municipal waste water.

The application of hydrocarbon degrading microorganisms in bioremediation applications is a promising approach to accelerate the clean-up of polluted soils. The use of microorganisms to accelerate the natural detoxification processes of toxic substances in the soil represents an alternative ecofriendly and low-cost method of environmental remediation compared to harmful incineration and chemical treatments.

Argulosis, caused predominantly by Argulus siamensis is a threatening ectoparasitic disease of Indian carp aquaculture. Vaccination against this parasite is a safe alternative to the harmful chemicals used for its control. Nitric oxide (NO), a signaling molecule plays an important role in immune mediated functions in different parasitic diseases.

The problem of food security arises along with the increase in world population. To meet the enormous food demands of growing population, farmers use traditional agricultural practices which mainly rely on use of chemical fertilizers and pesticides which are extensively harmful to the humans as well as environment. Therefore, there is an immense demand for an alternate strategy to increase the food productivity and quality which does not rely on use of these harmful chemicals.

Monoclonal antibodies (mAbs) as a class of therapeutic molecules are finding an increasing demand in the biotechnology industry for the treatment of diseases like cancer and multiple sclerosis. A key challenge associated to successful commercialization of mAbs is that from the various physical and chemical instabilities that are inherent to these molecules. Out of all probable instabilities, aggregation of mAbs has been a major problem that has been associated with a change in the protein structure and is a hurdle in various upstream and downstream processes.

During green revolution intensive use of chemical in agriculture might have helped to achieve a dramatic increase in crop yield ensuring food security in India, but meanwhile, the intensive application of chemical fertilizers and pesticides led to gradual decline in soil health and environment, and food safety became a major concern. This has raised question regarding the sustainability of agriculture/horticulture in the long term, urging attention towards sustainable production practices.

Environment pollution and the food shortage are the biggest problem faced by human beings. As the world population increase food requirement also increases. To fulfil the requirement of food the farmers are dependent on the chemical fertilizers which are harmful for environment. Thus the alternate to these problems are the use of biofertilizers.

Contamination of Oyster mushroom (var Pleurotus florida) bed with harmful fungi Trichoderma harzianum and Aspergillus flavus caused complete failure of mushroom crop. Management of T.harzianum and A. flavus was investigated by using four botanicals plant extracts viz.,Neem, Tulshi, Boas and Methi seed @ 5%, 10% , 20% concentration and GRAS chemicals viz., Boric acid, Calcium chloride, Sodium bi-carbonate and Sodium chloride @ 1%, 3%, 5% concentration respectively along with control under in vitro condition.
