Recent trends in life sciences research is more inclined towards interdisciplinary studies. Recent developments in the technologies have led to a better understanding of living systems and this has removed the demarcations between various disciplines of life sciences. A new trend in life science incorporates biological research involving a merger of diverse disciplines such as ecology, microbiology, toxicology and meteorology etc. The book encompasses topics on habitat ecology, biology of apis and apiculture, Cyanobacterial diversity, adaptation of microorganisms, Antibacterial activity, fungal glucose, prawn culture, concept of ecosystem, ozone depletion and global warming, halophilic archaea flourish in hypersaline environment and lycopene: preventive effects against cadmium injury in different tissues, Microbial enzymes and their applications, Phytochemical and antibacterial activity distributed throughout fifteen chapters for the benefits of graduate and postgraduate students as well as young researchers and scientists. In addition, this book provide newer techniques and the use of modern tools in achieving the potential of ecology, microbiology, toxicology, apiculture, aquaculture, meteorology, extremophiles, Immunotheraphy of Cancer and Marine bacterial enzymes this is all used to understand the challenges found in life sciences.
