Chitinolytic bacteria from alkaline hypersaline Mono Lake, California, USA
Chitinolytic activity was detected in sediment and water-column samples from Mono Lake, California, USA, using fluorogenic analogues. In order to learn more about chitin degradation in Mono Lake, we analyzed the phylogenetic composition of bacterial assemblages in chitin-enrichment cultures and associated with Artemia monica exuvia. We also isolated chitinolytic bacteria from aerobic and anaero...
متن کاملAnalysis of fae and fhcD genes in Mono Lake, California.
Genes for two enzymes of the tetrahydromethanopterin-linked C(1) transfer pathway (fae and fhcD) were detected in hypersaline, hyperalkaline Mono Lake (California), via PCR amplification and analysis. Low diversity for fae and fhcD was noted, in contrast to the diversity previously detected in a freshwater lake, Lake Washington (Washington).
متن کاملMaintaining meromixis in Lake Pavin ( Auvergne , France ) :
Lake Pavin is a deep meromictic lake. Its water column is divided into two parts: the mixolimnion, which is subjected to mixing during seasonal overturns; and the monimolimnion which remains unmixed. Using high precision and high frequency temperature and conductivity profiles along with continuous temperature measurements, this study reveals the presence of a sublacustrine, intermittent cold s...
متن کاملThe microbial arsenic cycle in Mono Lake, California.
Significant concentrations of dissolved inorganic arsenic can be found in the waters of a number of lakes located in the western USA and in other water bodies around the world. These lakes are often situated in arid, volcanic terrain. The highest concentrations of arsenic occur in hypersaline, closed basin soda lakes and their remnant brines. Although arsenic is a well-known toxicant to eukaryo...
متن کاملMicrobial response to salinity change in Lake Chaka, a hypersaline lake on Tibetan plateau.
Previous investigations of the salinity effects on the microbial community composition have largely been limited to dynamic estuaries and coastal solar salterns. In this study, the effects of salinity and mineralogy on microbial community composition was studied by using a 900-cm sediment core collected from a stable, inland hypersaline lake, Lake Chaka, on the Tibetan Plateau, north-western Ch...
