In this article we will discuss about:- 1. Definition of Biofilters 2. Microbial Potential of Biofilters 3. Biofilter Media 4. Mechanism. Biofiltration is a new technology used to purify contaminated air evolved from volatile organic and inorganic compounds by involving microorganisms. It is a low cost technology gradually becoming popular due to simple operational and waste-removal efficiencies. Biofiltration is the [...]
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 [...]
