Article Synopsis
  • - The study investigates how low concentrations of manganese(II) ions affect gene expression in a citric acid-producing Ascomycete fungus, specifically focusing on a hyper-producer strain used in industrial fermentation.
  • - Researchers found that of 11,846 genes analyzed, 963 were significantly different in their expression when manganese was deficient compared to when it was sufficient, with a notable increase in genes related to extracellular proteins and enzymes for polysaccharide breakdown.
  • - The deficiency in manganese led to upregulation of a citrate exporter gene, suggesting that the accumulation of citrate or acetyl-CoA plays a critical role in enhancing citric acid production, providing new insights into optimizing fermentation processes.

: Psoriasis is an immune-mediated chronic disorder associated with various comorbidities. Even though biologics and small-molecule inhibitors are the mainstay treatment for moderate-to-severe psoriasis, there is no current consensus regarding which agent should be used for a specific type of patient. This paper aims to test the reliability of blood-count-derived inflammatory markers in assessing treatment response to biologics and small-molecule inhibitors in psoriasis.

Today, antibiotic therapies that previously worked well against certain bacteria due to their natural sensitivity, are becoming less effective. Honey has been proven to inhibit the biofilm formation of some respiratory bacteria, however few data are available on how the storage time affects the antibacterial effect. The activity of black locust, goldenrod, linden and sunflower honeys from three consecutive years (2020, 2021, 2022) was analyzed in 2022 against Gram-negative (Haemophilus influenzae, H.

Alternative oxidase (Aox) is a terminal oxidase operating in branched electron transport. The activity correlates positively with overflow metabolisms in certain , converting intracellular glucose by the shortest possible path into organic acids, like citrate or itaconate. Aox is nearly ubiquitous in fungi, but gene multiplicity is rare.

is an important filamentous fungus used for the industrial production of citric acid. One of the most important factors that affect citric acid production is the concentration of manganese(II) ions present in the culture broth. Under manganese(II)-limiting conditions, the fungus develops a pellet-like morphology that is crucial for high citric acid accumulation.
