Comparative Study of Mechanical and Biological Pretreatment for Releasing Spores of Black Truffle .

It is well known that the number of true truffles in the wild is decreasing. The aim of the study was to develop an effective, simple and affordable method of asci disruption to release black truffle spores. It was shown that the spore release can be achieved by different ways, such as mechanical or biological destruction.

Black and white truffles as a source of neuroactive biogenic amines.

This study reports the first data about content of serotonin, histamine, and dopamine in black and white truffles fruiting body based on UHPLC-ESI-QqQ-MS/MS. Here we have demonstrated that black () and white () truffles are a source of biogenic amines. Also, we demonstrated the absence of correlation between the quality of truffles and the content of biogenic amines.

Detection of Pharmaceutical Contamination in Amphipods of Lake Baikal by the HPLC-MS Method.

Pollution by active ingredients is one of the most significant and widespread forms of pollution on Earth. Medicines can have a negative impact on ecosystems, and contamination can have unpredictable consequences. An urgent and unexplored task is to study the Lake Baikal ecosystem and its organisms for the presence of trace concentrations of active pharmaceutical ingredients.

The Effects of a High Concentration of Dissolved Oxygen on Actinobacteria from Lake Baikal.

Among the diversity of microorganisms, the rarest and least explored are microorganisms that live in conditions of high oxygen in the environment and can experience the effects of natural oxidative stress. Here we suggest that the actinobacteria of Lake Baikal, sampled in the littoral zone, may produce natural products with antioxidant activity. The current study aimed to assess the effects of experimentally increased amounts of oxygen and ozone on the morphology of actinobacteria, DNA mutations, and antioxidant potential.

Composition of nutrient media and temperature of cultivation imposes effect on the content of secondary metabolites of sp. isolated from a Siberian Cave.

Growth of human population leads to many global and medical problems. The problems include the crisis of health, antibiotic resistance, drug discovery, etc. Increasing antimicrobial resistance of microorganisms results in the need to screen natural products (incl.
