Characterization of chitin-glucan complex from Tremella fuciformis fermentation residue and evaluation of its antibacterial performance.

Int J Biol Macromol 2021 Jun 9. Epub 2021 Jun 9.

College of Food and Light Industry, Nanjing Tech University, Nanjing 211800, PR China.

Submerged fermentation of fungi is an efficient way to obtain extracellular polysaccharides, however, in this process, excess discarded biomass is produced. In this study, Tremella fuciformis mycelia were reused as the raw material to isolate a novel fungal chitin-glucan complex (CGC-TFM) using alkaline extraction. Characteristic analysis revealed that the CGC-TFM consisted of glucosamine/acetylglucosamine and glucose (GlcN:Glc = 26:74 mol%), indicating a reference to the β polymorphism of chitin-glucan complex, with the molecular weight and crystallinity index of 256 ± 3.

Development of a non-invasive method for monitoring variations in salt concentrations of seawater using nuclear technique and Monte Carlo simulation.

Appl Radiat Isot 2021 Aug 20;174:109784. Epub 2021 May 20.

Nuclear Engineering Institute - IEN/CNEN, Hélio de Almeida Street, Number 75, Rio de Janeiro, RJ, 21941-906, Brazil.

In the oil production industry, water is used as a fluid injected into the well to raise the oil when the well is depressurized. Water thus produced presents variations in the concentrations of dissolved salts, as there is a mixture of different types of water, related to its origin (such as connate water, sea water). Because it is reused in oil production, water needs to be monitored to maintain the standard suitable for its use as it can be hypersaline, contributing to the encrustation of pipes and contamination of underground water reservoirs.

Ubiquitin-Specific Protease 29 Regulates Cdc25A-Mediated Tumorigenesis.

Int J Mol Sci 2021 May 28;22(11). Epub 2021 May 28.

Graduate School of Biomedical Science and Engineering, Hanyang University, Seoul 04763, Korea.

Cell division cycle 25A (Cdc25A) is a dual-specificity phosphatase that is overexpressed in several cancer cells and promotes tumorigenesis. In normal cells, Cdc25A expression is regulated tightly, but the changes in expression patterns in cancer cells that lead to tumorigenesis are unknown. In this study, we showed that ubiquitin-specific protease 29 (USP29) stabilized Cdc25A protein expression in cancer cell lines by protecting it from ubiquitin-mediated proteasomal degradation.
