We report organic and inorganic carbon distributions and fluxes in a large (>2000 km2) oligotrophic, tropical lake (Lake Kivu, East Africa), acquired during four field surveys, that captured the seasonal variations (March 2007-mid rainy season, September 2007-late dry season, June 2008-early dry season, and April 2009-late rainy season). The partial pressure of CO2 (pCO2) in surface waters of t...

Abstract Gymnocypris przewalskii is the only high-land endemic teleost living in Qinghai Lake, largest saline–alkaline lake China. Its osmoregulatory physiology remains elusive due to a lack of precise identification response proteins. In present study, DIA/SWATH was used identify differentially expressed proteins (DEPs) under alkaline (pH = 10.1, carbonate buffer), saline (12‰, sodium chloride...

Lake Van is the largest saline soda lake in world and one of world’s few endorheic lakes greater than 3,000 km 2 surface area. Despite its huge size, no fish species have so far been known to permanently occur this due extreme environmental conditions. Here, we report discovery a population that inhabits some unique microbialites lake, at maximum depth 13 m about 500 offshore. We tested whether...

The high-altitude lakes are ecological habitats accommodating a vast diversity of microbial populations. These microbes efficient sources for variety enzymes. objective this study is to perform in-depth metagenomic profiling an artificial lake ecosystem located in the Sikkim Himalayan region, deciphering hydrocarbon degradation potential site and mining biocatalysts industrial importance. In pr...

In addition to biochemical, physiological and morphological analysis, molecular studies provide additional information for establishing phylogenetic relationships among different species and strains of the genus Dunaliella. In the present study, based on neighbor- joining analysis of the nuclear rDNA ITS sequence, a novel strain of the green algae Dunaliella viridis was identified from Maharlu ...
