The aim of this work was to optimize the process parameters through the statistical approach for the production of alpha amylase by Bacillus sp. in submerged fermentation (SMF). Initially critical physical and chemical process parameters influencing the enzyme production were identified by Plackett-Burman method (eleven variables, seven nutritional...

Hexavalent chromium is one of the most toxic heavy metals in the environment. It gets accumulated in soil and waste water, causing serious health hazards to environment and mankind. Among the different forms of chromium, Cr (III) and Cr (VI) are the most toxic forms of chromium due to their high permeability to biological cell membranes. Industrial...

World"s rapidly evolving population and its progressive attraction towards luxurious life has unsurprisingly led to an increase in anthropogenic sources of pollution. Environmental contamination of hexavalent chromium Cr(VI) is of serious concern for its toxicity as well as mutagenic and carcinogenic effects. Bacterial chromate reduction is a cost-...

Aims: Present study was done with the aim of isolation of efficient amylase producing bacterial isolates from soil. Amylase enzyme production, purification, SDS-PAGE and characterization of different important parameters as pH, temperature, substrate concentration etc. was done for obtaining maximum enzyme activity. Study Design: An experimental st...

Cyanobacteria (blue-green algae) are the photosynthetic organisms that are widely grown in all sorts of habitats including aquatic and terrestrial environments. Today, the agricultural sector is highly dependent on chemical fertilizers to enhance the crop production in order to meet the demand for food around the globe which have severe negative ef...

Naphthalene is a simple polycyclic aromatic hydrocarbon (PAH) regarded as a common environmental pollutant. A total number of 16 bacterial isolates obtained from various petroleum contaminated sites of Gwalior (MP), India were screened for their naphthalene degradation potential. Enrichment method was used for the isolation of bacteria by amending...

Natural water resources are at high risk of heavy metal contamination by the introduction of untreated industrial, domestic and sewage effluents, that leads to scarcity of pure water. Access to potable water is a fundamental right of mankind as well as all living beings. This has led a high pressure on finding out most effective, economic and envir...

Pollution is one of the serious problems around the globe today. It has negative impacts on environmental health and mankind. Environmental pollution attributed to air and water affects our health and cause serious diseases. Agnihotra is a vedic method to reduce the pollution from the environment. It is a type of holy sacrifice, performed at sunris...
