  • Cell to Cell Communication and Social Networking in Plant Pathogenic Bacteria ( 1401 reads)   

    It was a common perception that, bacterial cells are primarily selfish individuals, but, in recent past, it has become clear that, they behave like well organized social organisms like us. Such cell to cell networking is called Quorum Sensing. For such communication they employ low molecular weight, diffusible signals and upon achieving a certain concentration (quorum concentration), it triggers certain set of gene expression. Recent findings have emanated that bacteria are not limited to communication within their own species but are capable of understanding interspecific messages also. More to this, more findings are coming up in timeline for quorum sensing and social chit-chat mechanism in fungus and as well other organisms also. - Category: Environmental Biotechnology
  • Organic Farming Practices: Boon for Natural Biodiversity ( 2035 reads)   

    Organic farming practice generates clear benefits for biodiversity in comparison to inorganic and conventional agricultural practices. As in organic farming, semi natural habitat conditions are maintained, hence it hosts 30% more species and around 50% more individuals than conventional farming practices (based on reviews). This is because lower farming intensities and higher proportion of semi natural habitat condition enables location specific animal and plant species to thrive on organic farms and in return allow farmers to have more benefits from an intact and thus sustainably functioning ecosystem. - Category: Agriculture
  • Biodegradable Plastics: Green Option for Tackling Plastic Pollution ( 1533 reads)   

    The biodegradable polymers could be an alternative to the conventional plastic materials. These polymers being biodegradable can be disposed off in safe and ecologically sound manner, through disposal processes (waste management) like composting, soil application, and biological wastewater treatment. Bio-based and biodegradable plastics can form the basis for environmentally preferable, sustainable alternative to current materials which are exclusively based on petroleum feed stocks. These bio-based materials offer value in the sustainability/ life-cycle equation by being a part of the biological carbon cycle and as well are a green option for tackling the plastic pollution - Category: Environmental Biotechnology
