Screening and characterizing indigenous yeasts, lactic acid bacteria, and acetic acid bacteria from cocoa fermentation in Hainan for aroma Development.

Fermentation is crucial for inducing desirable flavor and aroma profiles in cocoa products. This research focused on identifying microbial strains isolated from spontaneous cocoa fermentation in Hainan through 16S and Internal Transcribed Spacer (ITS) sequencing. Pectinase activity was screened, and metabolic dynamics of sugars and organic acids were analyzed using high-performance liquid chromatography.

Cooperative Anion-π Catalysis with Chiral Molecular Cages toward Enantioselective Desymmetrization of Anhydrides.

Exploiting novel noncovalent interactions for catalysis design represents a fascinating direction. For the flexible and relatively weak anion-π interactions, manipulation of two or more π-acidic surfaces for cooperative activation is highly desirable. Here, we demonstrate the strategy of cooperative anion-π catalysis based on chiral molecular cages with V-shaped electron-deficient cavities for synergic binding and activation of dicarbonyl electrophiles toward highly enantioselective desymmetrization transformation.

TDP-43 Cryptic RNAs in Perry Syndrome: Differences across Brain Regions and TDP-43 Proteinopathies.

Background: Perry syndrome (PS) is a rare and fatal hereditary autosomal dominant neurodegenerative disorder caused by mutations in dynactin (DCTN1). PS brains accumulate inclusions positive for ubiquitin, transactive-response DNA-binding protein of 43 kDa (TDP-43), and to a lesser extent dynactin.

Objectives: Little is known regarding the contributions of TDP-43, an RNA binding protein that represses cryptic exon inclusion, in PS.

Effects of oil pollution on the growth and rhizosphere microbial community of Calamagrostis epigejos.

Bacteria, fungi, archaea, and viruses are reflective organisms that indicate soil health. Investigating the impact of crude oil pollution on the community structure and interactions among bacteria, fungi, archaea, and viruses in Calamagrostis epigejos soil can provide theoretical support for remediating crude oil pollution in Calamagrostis epigejos ecosystems. In this study, Calamagrostis epigejos was selected as the research subject and subjected to different levels of crude oil addition (0 kg/hm, 10 kg/hm, 40 kg/hm).

UV-C Exposure Enhanced the Cd Adsorption Capability of the Radiation-Resistant Strain sp. M1-B02.

Microbial adsorption is a cost-effective and environmentally friendly remediation method for heavy metal pollution. The adsorption mechanism of cadmium (Cd) by bacteria inhabiting extreme environments is largely unexplored. This study describes the biosorption of Cd by sp.
