The bacterial light-dependent energy metabolism can be divided into two types: oxygenic and anoxygenic photosynthesis. Bacterial oxygenic photosynthesis is similar to plants and is characteristic for cyanobacteria. Bacterial anoxygenic photosynthesis is performed by anoxygenic phototrophs, especially green sulfur bacteria (GSB; family Chlorobiaceae) and purple sulfur bacteria (PSB; family Chromatiaceae). In anoxygenic photosynthesis, hydrogen sulfide (H2S) is used as the main electron donor, which differs from plants or cyanobacteria where water is the main source of electrons. This review mainly focuses on the microbiology of GSB, which may be found in water or soil ecosystems where H2S is abundant. GSB oxidize H2S to elemental sulfur. GSB possess special structures—chlorosomes—wherein photosynthetic pigments are located. Chlorosomes are vesicles that are surrounded by a lipid monolayer that serve as light-collecting antennas. The carbon source of GSB is carbon dioxide, which is assimilated through the reverse tricarboxylic acid cycle. Our review provides a thorough introduction to the comparative eco-physiology of GSB and discusses selected application possibilities of anoxygenic phototrophs in the fields of environmental management, bioremediation, and biotechnology.

“…The emerging field of science communication combines various approaches to educate and engage the public in the complex science realm to promote evidence-based policy and, specifically, in nature protection (Bickford et al, 2012). De Leon et al (2023) present the data collected and lessons learned from using Winogradsky Columns in public spaces for teaching about an important saline lake. Authors worked with museums in Utah to create Winogradsky Columns that would highlight aesthetic properties of the Great Salt Lake ecosystem, which has a salinity gradient from the freshwater wetlands to salt saturation.…”

Saline lakes are widespread on all continents. Since 1979, an informal international association of salt lake researchers from a variety of disciplines has sponsored a series of triennial conferences to foster scientific exchange and our understanding of saline lakes. International Society for Salt Lake Research (ISSLR, www.isslr.org) was founded in 1994 to establish effective liaison between persons interested in any aspect of inland saline waters, to encourage these interests, and to educate the public in the scientific use, management, and conservation of salt lakes. ISSLR conferences are held triennially. The conferences are usually hosted by a local University or research institution and provide an excellent opportunity for networking among globally dispersed researchers.The 14 th International Conference on Salt Lake Research was held online during October 18-22, 2021 and hosted in Murcia, Spain. The conference was organized by the ISSLR together with the Institute of Saltscapes and Salt Heritage (IPAISAL), an Non-Governmental Organization devoted to the research and dissemination of the natural, cultural, and human values of saltscapes based in Spain. The conference was initially planned to be held in the autumn of 2020, but the travel restrictions imposed by the COVID-19 pandemic advised to postpone it * Egor ZADEREEV was financially supported by the State Assignment of the Ministry of Science and Higher Education of the Russian Federation (No.

Fungi of Great Salt Lake, Utah, USA: a spatial survey

The natural system at Great Salt Lake, Utah, USA was augmented by the construction of a rock-filled railroad causeway in 1960, creating two lakes at one site. The north arm is sequestered from the mountain snowmelt inputs and thus became saturated with salts (250-340 g/L). The south arm is a flourishing ecosystem with moderate salinity (90-190 g/L) and a significant body of water for ten million birds on the avian flyways of the western US who engorge themselves on the large biomass of brine flies and shrimp. The sediments around the lake shores include calcium carbonate oolitic sand and clay, and further away from the saltwater margins, a zone with less saline soil. Here a small number of plants can thrive, including Salicornia and Sueda species. At the north arm at Rozel Point, halite crystals precipitate in the salt-saturated lake water, calcium sulfate precipitates to form gypsum crystals embedded in the clay, and high molecular weight asphalt seeps from the ground. It is an ecosystem with gradients and extremes, and fungi are up to the challenge. We have collected data on Great Salt Lake fungi from a variety of studies and present them here in a spatial survey. Combining knowledge of cultivation studies as well as environmental DNA work, we discuss the genera prevalent in and around this unique ecosystem. A wide diversity of taxa were found in multiple microniches of the lake, suggesting significant roles for these genera: Acremonium, Alternaria, Aspergillus, Cladosporium, Clydae, Coniochaeta, Cryptococcus, Malassezia, Nectria, Penicillium, Powellomyces, Rhizophlyctis, and Wallemia. Considering the species present and the features of Great Salt Lake as a terminal basin, we discuss of the possible roles of the fungi. These include not only nutrient cycling, toxin mediation, and predation for the ecosystem, but also roles that would enable other life to thrive in the water and on the shore. Many genera that we discovered may help other organisms in alleviating salinity stress, promoting growth, or affording protection from dehydration. The diverse taxa of Great Salt Lake fungi provide important benefits for the ecosystem.
