Disentangling the lifestyle of bacterial communities in tropical soda lakes.

Microbial lifestyles may reveal niche-specific signatures and can contribute to detecting the effects of abiotic fluctuations on biogeochemical cycles. Microorganisms make a tradeoff between optimizing nutrient uptake, improving biomass yield, and overcoming environmental changes according to environmental hostility. Soda lakes are natural environments rich in carbonate and bicarbonate water, resulting in elevated pH and salinities that frequently approach saturation.

Phylogenomic analysis of (Nostocales, Cyanobacteria).

The saline-alkaline lakes (soda lakes) are the habitat of the haloalkaliphilic cyanobacterium , the type species of this genus. To obtain robust phylogeny of this type species, we have generated whole-genome sequencing of the bloom-forming strain CCIBt3563 isolated from a Brazilian soda lake. This strain presents the typical morphology of with short and curved trichomes with apical heterocytes established after separation of paired intercalary heterocytes and also regarding to cell dimensions.
