“…The alkaline pH adaptation of Y. lipolytica caused a general decrease in the storage lipid profile (Figure 3). The similar decrease in the total storage lipids at alkaline ambient pH was also demonstrated for the Sodiomyces tronii ascomycete [20]. The decrease in DAG levels in storage lipids under thermal and combined stresses suggested that under these conditions, the cells could use the storage lipids as substrates ( Figure 3A).…”

“…Moreover, mannitol comprises more than half of the total sugar amount in the cytosol of some alkali-tolerant fungi, namely Acrostalagmus luteoalbus, Chordomyces antarcticus, and alkaliphile species of Sodiomyces magadii and S. alkalinus. Its relative composition increased while pH lowed to acidic pH [20]. The mannitol level in Y. lipolytica also increased at elevated concentrations of sodium chloride [12].…”

“…Cell membranes, as a defense barrier of a cell, alter their lipid composition in response to various kinds of stress. Alkaliphilic micromycete of Sodiomyces tronii contain more sterols and sphingolipids in the membrane lipids at acidic ambient pH [20]. Non-optimum pH invoked significant changes in the degree of fatty acid unsaturation, amount of the sterols, and phosphatidylcholine (PC) fractions in the membrane lipids in alkaliphilic Sodiomyces magadii and alkalinus, as well as alkali-tolerant Acrostalagmus luteoalbus and Chordomyces antarcticus [20].…”

Microorganisms cope with a wide range of environmental challenges using different mechanisms. Their ability to prosper at extreme ambient pH and high temperatures has been well reported, but the adaptation mechanism often remains unrevealed. In this study, we addressed the dynamics of lipid and sugar profiles upon different cultivation conditions. The results showed that the cells grown at various pH and optimal temperature contained mannitol as the major cytosol sugar alcohol. The elevated temperature of 38 °C led to a two- to three-fold increase in total cytosol sugars with concurrent substitution of mannitol for trehalose. Lipid composition in the cells at optimal temperature changed insignificantly at any pH tested. The increase in the temperature caused some drop in the storage and membrane lipid levels, remarkable changes in their composition, and the degree of unsaturated fatty acids. It was shown that the fatty acid composition of some membrane phospholipids varied considerably at changing pH and temperature values. The data showed a pivotal role and flexibility of the sugar and lipid composition of Y. lipolytica W29 in adaptation to unfavorable environmental conditions.

Marynowski et al International Journal of Coal Geology 201 (2019) 51-61 found that some alkaliphilic fungi change their carbohydrate composition at a very high pH (glucose is substituted by mannitol and arabitol). The high concentration of fungal biomarkers in this Late Cretaceous section suggests their important role in this period of time.…”

A B S T R A C TTrehalose, mannitol and arabitol are the main saccharides of extant fungal metabolism, but their occurrence and distribution in geological materials have rarely been considered. Here, we identify these sugars in Miocene lignites and for the first time in Late Cretaceous mudstones and coals. The co-occurrence of trehalose, mannitol and arabitol in the sedimentary rocks investigated suggests their fungal origin, because these three saccharides are major compounds present in most modern fungi, including the very common mycorrhizal and wood-rotting groups. Therefore, we conclude that these sugars should be treated as new fungal biomarkers (biomolecules) present in geological rocks. Trehalose and mannitol are major compounds in total extracts of the samples and a sum of their concentration reaches 4.6 μg/g of sample. The arabitol concentrations do not exceed 0.5 μg/g, but in contrast to trehalose, the concentration correlates well with mannitol (R 2 = 0.94), suggesting that they have the same, translocatory role in fungi. Based on the trehalose vs. mannitol and arabitol distributions in Cretaceous samples and their comparison with data for modern fungi, we preliminarily conclude that the coal seams from the Rakowice Małe (SW Poland) section were formed during warmer climatic periods than the overlying sediments. Furthermore, no DNA could be isolated from the samples of lignites and overlying sediments, whereas it was abundant in the control samples of maple, birch and oak wood degraded by fungi. This indicates an absence of recent fungi responsible for decay in lignites and implies that the saccharide origin is connected with ancient fungi.Other sugar alcohols and acids like D-pinitol, quinic acid and shikimic acid, were found for the first time in sedimentary rocks, and their source is inferred to be from higher plants, most likely conifers. The preservation of mono-and disaccharides of fungal origins in pre-Palaeogene strata implies that compounds previously thought as unstable can survive for tens to hundreds of millions of years without structural changes in immature rocks unaffected by secondary processes.Saccharides, ubiquitous biomolecules in both plant and animal kingdoms, are common in marine and terrestrial environments (Klok et al.

ANIMALSThe purpose of a biobank is to accumulate collections that adequately reflect the multidimensional structure of biodiversity (BD), making it possible to explore its various manifestations. An analysis of the scientific status of zoological collections was carried out [1], and it was shown that the collections perform the function of a research sample in BD studies. Their main characteristics are their representativeness, which is further detailed by their informational value, reliability, systemic character, scope, structure, etc.The studies in the "Animals" section are aimed at analyzing key aspects of BD on the basis of an integrated approach combining phylogenomic and phylo-ABSTRACT The "Noah's Ark" project, afoot at M.V. Lomonosov Moscow State University since 2015 and aimed at studying biodiversity, is the largest ongoing Russian project in life sciences. During its implementation, several hundred new species have been described; a comprehensive genetic and biochemical characterization of these species, as well as that of the pre-existing specimens in Moscow University's collections, has been performed. A consolidated IT system intended to house the knowledge generated by the project has been developed. Here, we summarize the investigations around the Moscow University classical biocollections which have taken place within the framework of the project and discuss future promise and the outlook for these collections.
