Abstract

The effect of phenol on the growth rate and respiration was studied with the yeast Candida mycoderma cultivated in the pH-static conditions with continuous recording of the principal kinetic parameters of the population. The kinetics of growth inhibition with phenol was studied. Adaptation of the culture in terms of the growth rate and the rate of oxygen uptake was detected within 10--15 hours of cultivation. A new strain of C. mycoderma Phen. R. isolated using the technique of autoselection upon continuous cultivation for a long period of time, at a phenol concentration of 1.5 g/l in the growth medium, had an elevated growth rate (2.2 times higher) in these conditions as compared with the parent culture and required less oxygen.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.
