Abstract
Most Fusarium species are known as endophytes and/or phytopathogens of higher plants and have a worldwide distribution. Recently, information discovered with molecular tools has been also published about the presence of these fungi in the microbiome of truffle fruiting bodies. In the present work, we isolated and identified three Fusarium strains from truffle fruiting bodies. All isolates were assigned to the same species, F. commune, and the strains were deposited in the All-Russian Collection of Microorganisms under accession numbers VKM F-5020, VKM F-5021, and VKM F-5022. To check the possible effects of the isolated strains on the plants, the isolates were used to infect sterile seedlings of Sarepta mustard (Brassica juncea L.). This model infection led to a moderate suppression of the photosynthetic apparatus activity and plant growth. Here, we present characteristics of the F. commune isolates: description of the conidial morphology, pigmentation, and composition of the mycelium fatty acids. Overall, this is the first description of the Fusarium cultures isolated from truffle fruiting bodies. Possible symbiosis of the F. commune strains with truffles and their involvement in the cooperative fatty acid production are proposed.

Fungal Biol 2023; 127:909-917.

Abstract
Xerophilic fungi accumulate a large amount of glycerol in the cytosol to counterbalance the external osmotic pressure. But during heat shock (HS) majority of fungi accumulate a thermoprotective osmolyte trehalose. Since glycerol and trehalose are synthesized in the cell from the same precursor (glucose), we hypothesised that, under heat shock conditions, xerophiles growing in media with high concentrations of glycerol may acquire greater thermotolerance than those grown in media with high concentrations of NaCl. Therefore, the composition of membrane lipids and osmolytes of the fungus Aspergillus penicillioides, growing in 2 different media under HS conditions was studied and the acquired thermotolerance was assessed. It was found that in the salt-containing medium an increase in the proportion of phosphatidic acids against a decrease in the proportion of phosphatidylethanolamines is observed in the composition of membrane lipids, and the level of glycerol in the cytosol decreases 6-fold, while in the medium with glycerol, changes in the composition of membrane lipids are insignificant and the level of glycerol is reduced by no more than 30%. In the mycelium trehalose level have increased in both media, but did not exceed 1% of dry weight. However, after exposure to HS the fungus acquires greater thermotolerance in the medium with glycerol than in the medium with salt. The data obtained indicate the interrelation between changes in the composition of osmolytes and membrane lipids in the adaptive response to HS, as well as the synergistic effect of glycerol and trehalose.

Abstract
To improve liposomes’ usage as drug delivery vehicles, cryoprotectants can be utilized to prevent constituent leakage and liposome instability. Cryoprotective agents (CPAs) or cryoprotectants can protect liposomes from the mechanical stress of ice by vitrifying at a specific temperature, which forms a glassy matrix. The majority of studies on cryoprotectants demonstrate that as the concentration of the cryoprotectant is increased, the liposomal stability improves, resulting in decreased aggregation. The effectiveness of CPAs in maintaining liposome stability in the aqueous state essentially depends on a complex interaction between protectants and bilayer composition. Furthermore, different types of CPAs have distinct effective mechanisms of action; therefore, the combination of several cryoprotectants may be beneficial and novel attributed to the synergistic actions of the CPAs. In this review, we discuss the use of liposomes as drug delivery vehicles, phospholipid–CPA interactions, their thermotropic behavior during freezing, types of CPA and their mechanism for preventing leakage of drugs from liposomes.
