In this article we will discuss about the biodeterioration of various materials. 1. Biodeterioration of Stored Plant Food Material: The stored (unprocessed) plant material (fruits, seeds, etc.) are usually decayed due to post harvest attack of bacteria and fungi. This kind of spoilage is called biodeterioration. However, loss of plant materials before harvest is covered in plant pathology. The microbes [...]
In this article we will discuss about the microbial degradation of petroleum and xenobiotic. 1. Microbial Degradation of Petroleum (Hydrocarbon): Petroleum and its products are the hydrocarbons. It is a rich source of organic matter and is oxidised if comes in contact with air and moisture. There are some microorganisms which cleave the hydrocarbons into simpler molecules. Bioremediation is an [...]
There are four main physiological mechanism of heavy metal resistance: (a) Inactivation, (b) Impermeability, (c) By- pass, and (d) Altered target site(s). On the other hand, earlier studies reported that fungi tend to survive heavy metal stress either by adaptation or mutation. Not only fungi but few algae such as Stigeoclonium tenue can grow in a zinc-rich effluent and showed [...]
