Greetings!
Hydrosphere, the aquatic environment of the earth, supports numerous living things. Microbes are minute organisms that occur in all environments and are therefore omnipresent. Microorganisms in the aquatic environment affect man and other organisms either positively or negatively, directly or indirectly. In other words, these minute living things may be beneficial or harmful to man, his activities as well as other natural resources. For purposes of completeness, it is noted that the presence of some microorganisms in water may sometimes have no apparent or visible effect, being neutral to the ecosystem.
The newly evolved aquaculture system, called “Biofloc Technology (BFT)” is considered as an environmental friendly and efficient alternative system for aqua farming. Bioflocs are the mixer of detritus with associated microorganisms such as bacteria, algae, protozoea, rotifers, copepods, nematodes etc. This technology facilitates recycling of nutrients and converts nitrogenous waste into protein, thereby reduce water pollution, with the involvement of these microorganisms. The proteins produced in bioflocs by bacteria are called single cell proteins, similar to proteins originating from yeast and algae. Bioflocs are able to assimilate waste nutrients (or pollutants) from the water column, cleaning the water and producing new proteins.
In this issue, the importance of Biofloc Technology is highlighted, which help the students, researchers and industry to understand the basic aspects of such eco-friendly technology, aiming to encourage for further research. In addition, same interesting informations on fossil fuel, synthetic chromosome, role of microbes in chemical energy are also included.
