Difference between Oligotrophic and Eutrophic Lake
Oligotrophic vs Eutrophic Lakes Lake Ecosystem is an example for a lentic ecosystem. An aquatic ecosystem with stationary or relatively still water is called lentic ecosystem. Based on the trophic state* and productivity, the lake ecosystem is divided into three categories. (1). Oligotrophic lakes (2). Eutrophic lakes (3). Mesotrophic lakes […]

Batch Fermentation and Continuous Fermentation are the two commonly adopted Industrial Fermentation methods for the scale production of microbial biomass or metabolites. Batch Fermentation: Here the fermenter is first filled with the raw material (carbon source). Then the microbes are added and allowed to ferment the raw material under optimum pH […]

Difference between Arteries and Veins: The circulatory system in an organism ensures the transport of oxygen, nutrients, carbon dioxide and hormone throughout the body. The blood circulatory system in an animal is facilitated by the heart (the blood pumping organ) and blood vessels (closed pipelines which carry out the circulation […]
