Biodegradation is nature's way of recycling wastes, or breaking down organic matter, carried out by living microorganisms such as bacteria, fungi, insects, worms etc., into nutrients. In nature, the waste products from one organism become the food for others. Thus everything gets recycled and there is no waste. The term biodegradation is often used in relation to ecology, waste management and mostly associated with environmental remediation.
In the last few decades, highly toxic organic compounds, like fuels, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), pesticides, dyes and heavy metals, have been synthesized and released into the environment for direct or indirect application. Biological processes play a major role in the removal of contaminants and take advantage of the catabolic versatility of microorganisms to degrade or convert such compounds. In this issue, a review of microbial degradation of cyanide waste is included.
In addition, other interesting topics such as plastic-munching bacteria, oil degrading bacteria, discovery of CRISPR like immune system in virus are included.
