Dear Readers,



Contaminants to the environment causing ecological problems leading to imbalance in nature is of global concern. Understanding adverse effects of contaminants leads to improved regulation, management and control. The ideal solution for pollution abatement is the use of biological systems. Bioremediation, the most effective innovative technology, includes bio-stimulation (stimulating viable native microbial population), bio-augmentation (artificially introduction of viable population), phytoremediation (plants) and phycoremediation (microalgae), its central thrust depends on microbes. Phycoremediation is environmental friendly and has been widely used for the disposal of industrial wastes.


Nowadays marine microorganisms have fascinated many biologists of their unique, biologically active secondary metabolites especially from fungi. Many secondary metabolites from marine sources tend to be more highly bioactive against many types of tumor and viruses compared to the terrestrial derived bio-products. In spite of the sea’s vast potential identified, this domain remains relatively unexplored.


In this issue, you will find articles on the developments, importance and current practices of phycoremediation for industrial effluent and also on the natural functions of secondary metabolites from endophytic fungi of marine resources especially from mangrove origin. Other interesting features of this issue takes you through an exciting scenario where bacteria collaborate to sense arsenic and bioluminescent bacteria may illuminate your house - path - breaking developments to utilize microorganisms for the larger benefit of mankind.
