We report the draft genome sequence of strain YE2023, isolated from a pulp of a laboratory-scale bioleach reactor. The genome is 3,221,954 Mbp long with a guanine-cytosine content of 58.16%.

In the present study, the effect of additional carbon sources (carbon dioxide and molasses) on the bio-oxidation of a pyrite-arsenopyrite concentrate at temperatures of 40-50 °C was studied, and novel data regarding the patterns of the bio-oxidation of gold-bearing sulfide concentrates and the composition of the microbial populations performing these processes were obtained. At 40 °C, additional carbon sources did not affect the bio-oxidation efficiency. At the same time, the application of additional carbon dioxide improved the bio-oxidation performance at temperatures of 45 and 50 °C and made it possible to avoid the inhibition of bio-oxidation due to an increase in the temperature.

Background: Cancer cachexia (CC) is a severe complication during the last stages of the disease, which is characterized by the substantial loss of muscle and fat mass. Currently, there is no effective treatment of CC. Erythropoietin plays tissue-protective role in different tissues.

Tank bio-oxidation is a biohydrometallurgical technology widely used for metal recovery from sulfide concentrates. Since carbon availability is one of the key factors affecting microbial communities, it may also determine the rate of sulfide concentrate bio-oxidation. The goal of the present work was to evaluate the effect of carbon sources on the bio-oxidation of the concentrate containing 56% pyrite and 14% arsenopyrite at different temperatures (40 and 50 °C) in stirred tank reactors.

The fibrous sheath is a unique cytoskeletal structure surrounding the axoneme and outer dense fibres of the sperm flagellum. Dysplasia of the fibrous sheath (DFS) is a defect of spermatozoa observed in severe asthenozoospermic patients and characterised by morphologically abnormal flagella with distorted fibrous sheaths. Sperm-specific glyceraldehyde-3-phosphate dehydrogenase (GAPDS) is a glycolytic enzyme that is tightly associated with the fibrous sheath of the sperm flagellum.
