Salt lakes/Soda lakes Definition Salt lakes are naturally occurring highly alkaline aquatic bodies, widely spread throughout the world. Salt lakes are ecosystem with extremely high pH (up to 11) and salinity (up to saturation) due to the presence of high concentrations of sodium carbonate. Salt lakes, located in Kenya and Tanzania (Bogoria, Magadi, Natron), in Egypt (Wadi Natrun), and California (Mono Lake) are good example of typical salt lakes. Another area abundant in saline alkaline lakes is Central Asia (south Siberia and north-east China). Here the lakes are much smaller, more shallow, and water regimen is unstable due to freezing winter period which cause fluctuations of the water salinity and temperature. There are so many salt lakes and salt deserts around the world. Some of them are listed below.           source:  https://d-nb.info/968508480/34 Formation of Salt Lakes One of the theory suggest that rocks...

Sometime during our studies we come across many terms and words which we do not remember or we are not familiar with. In that situation either we consult a dictionary or google the word. So I thought about to make a series which give general overview of microbiology related terms. I am trying to provide as much as possible. So today the word is Actinomycetes. Definition Actinomycetes also called as Actinobacteria are unicellular, gram positive, rod shaped, spore forming, and facultative anaerobic bacteria. They don’t have true cell wall like bacteria and can produce mycelium like fungi and because of this noted ability, actinomycetes also known as connected link between bacteria and fungi. Discovery The term actinomycetes means “ray fungus” in Greek.  It is first discovered by Ferdinand Cohn in 1875 from human lacrimal duct and named it  Streptothrix foersteri . In 1878, C.O. Harz named an organism that he isolated from a case of bovine lumpy jaw, as...
