Agriculture have a significant portion of the economies of world and therefore can contribute toward major continental priorities such as eradicating poverty, hunger, rapid industrialization, economic diversification, sustainable resource utilization, investments, and environmental management. Plant-associated microbiomes have tremendous potential to improve plant resilience and yields in farming systems. There is increasing evidence that biological technologies that use microbes or their metabolites can enhance nutrient uptake and yield, control pests and mitigate plant stress responses. Microbiological achievements of recent years have emerged as powerful tool to improve quality attributes of sustainable agriculture and environmental health. The chemical fertilizers used in the agriculture to increase yields but kill microflora, pests, and weeds, it have a big harmful impact on the ecosystem. Because of current public concerns about the side effects of agrochemicals, there is an increasing interest in improving the understanding of cooperative activities among plants and rhizosphere microbial populations. The review deals with microbes in biotechnology and their diversified applications in agriculture as bio-fertilizers, bio-pesticides, bio-herbicides, bio-insecticides, fungal based bio-insecticides and viral based bioinsecticides. Finally, a brief highlight has been given on the role of microbiology on development of sustainable agriculture and environment friendly approach to increase crop production and environmental health.

Benzene, Toluene and Xylene (BTX) are present in both exhaust and evaporative emission from vehicles and at the fuel delivery outlets in the urban atmosphere. The aim of the present study was to understand ambient air quality with respect to carcinogenic pollutants i.e. BTX (Benzene, Toluene and Xylene). Study was conducted in different petrol pumps at Satna city. Air samples were collected and analyzed as per CPCB guidelines/BIS Standards. BTX sample were analyzed using gas chromatograph (GC) fitted with capillary column and flame ionization detector (FID).Benzene causes deleterious effects on human beings, therefore, it is a matter of concern that everyone should take immediate action to control VOCs especially BTX. These types of compounds once released in the environment, usually evaporate quickly into the air. The primary man made sources of BTX into the environment are via emissions from motor vehicles, losses during petrol marketing and cigarette smoke. In the present study benzene was found in the range of 2-12 μg/m³ and it was higher than the permissible limit prescribed by the CPCB is 5 μg/m³ for benzene and it may be cause of health concern.
