Exploration of Microbial Diversity and Community Structure of Lonar Lake: The Only Hypersaline Meteorite Crater Lake within Basalt Rock
Lonar Lake is a hypersaline and hyperalkaline soda lake and the only meteorite impact crater in the world situated in basalt rocks. Although culture-dependent studies have been reported, a comprehensive understanding of microbial community composition and structure in Lonar Lake remains elusive. In the present study, microbial community structure associated with Lonar Lake sediment and water sa...
متن کاملLinking DNRA community structure and activity in a shallow lagoonal estuarine system
Dissimilatory nitrate reduction to ammonium (DNRA) and denitrification are two nitrate respiration pathways in the microbial nitrogen cycle. Diversity and abundance of denitrifying bacteria have been extensively examined in various ecosystems. However, studies on DNRA bacterial diversity are limited, and the linkage between the structure and activity of DNRA communities has yet to be discovered...
متن کاملDevelopment of a Halotolerant Community in the St. Lucia Estuary (South Africa) during a Hypersaline Phase
BACKGROUND The St. Lucia Estuary, Africa's largest estuarine lake, is currently experiencing unprecedented freshwater deprivation which has resulted in a northward gradient of drought effects, with hypersaline conditions in its northern lakes. METHODOLOGY/PRINCIPAL FINDINGS This study documents the changes that occurred in the biotic communities at False Bay from May 2010 to June 2011, in ord...
متن کاملMicrobiological study of a hypersaline lake in French Somaliland.
In a study of a lake having a higher concentration of salts than the Dead Sea, all of the heterotrophic bacteria isolated were aerobes; no strictly anaerobic strains were found. Ninety percent of the strains were euryhalines and ten percent were strict halophiles. The extreme halophiles belonged to the species Halobacterium trapanicum and Halococcus morrhuae.
متن کاملCiliate species Epistylis sp. cause to fish deaths
A group of unicellular ciliates such Epistylis are amplified at aquatic environment by governor of food contamination. In the case, fixed ciliates like Epistylis are colonized as Ectoparasites on fishes, Aquatic crustaceans, Turtle and Aquatic plants. They graze food residue or bacteria or decompose residue like Ectoparasites. In this case, Epistylis licking their stems to the surface body of f...
