A new stabilizing substrate derived from cellulose crystallite aggregates (CCA) is presented in its use for tissue culture and regeneration of cauliflower (Brassica oleracea L.), particularly at the stage of root formation. The material is suitable instead of agar for the large scale propagation of cultured plants. Frequently growth promoting effects are being observed with the medium.

Antarctic snow harbors diverse microorganisms, including pigmented algae and bacteria, which create colored snow patches and influence global climate and biogeochemical cycles. However, the genomic diversity and metabolic potential of colored snow remain poorly understood. We conducted a genome-resolved study of microbiomes in colored snow from 13 patches (7 green and 6 red) on the Fildes Peninsula, Antarctica.

Neddylation is a process of attaching neuronal precursor cell-expressed developmentally downregulated protein 8 (NEDD8) to substrates for the protein function modulation via enzymatic cascades involving NEDD8-activating enzyme (E1), NEDD8-conjugating enzyme (E2), and NEDD8 ligase (E3). Defective in cullin neddylation 1 (DCN1) serves as a co-E3 ligase, that can simultaneously bind E2 UBE2M and cullin proteins to stabilize the catalytic center of the Cullin-Ring E3 ligase (CRL) complex, thereby promoting cullin neddylation. Neddylation is reported to be activated in diverse human diseases, and inhibition of protein neddylation has been regarded as a promising anticancer therapy.

Enzyme functional analysis is a multifaceted process that can be used for various purposes, such as screening for specific activities, as well as developing, optimising, and validating processes or final products. Functional analysis methods are crucial for assessing enzyme performance and catalytic properties. Laccase, a well-known blue multi-copper oxidase, holds immense potential in diverse industries such as pharmaceuticals, paper and pulp, food and beverages, textiles, and biorefineries due to its clean oxidation process and versatility in handling a wide range of substrates.

The sluggish kinetics of the hydrogen evolution reaction (HER) result in a high overpotential in alkaline solutions. A high-curvature metal oxide heterostructure can effectively boost the electrocatalytic HER by leveraging the tip-enhanced local electric field effect. Herein, NiP/NiMoO nanocones were synthesised on a nickel foam (NF) substrate by etching a metal-organic framework template.

Near-infrared light response catalysts have received great attention in renewable solar energy conversion, energy production, and environmental purification. Here, near-infrared photodegradation is successfully achieved in rare earth single atom anchored NaYF@g-CN heterojunctions by the synergistic effect of Z-scheme heterojunction and antenna of rare earth single atoms. The UV-vis light emitted by Tm can not only be directly absorbed by g-CN to generate electron-hole pairs, realizing efficient energy transfer, but also be absorbed by NaYF substrate, and generating photo-generated electrons at its impurity level, transferring the active charge to the valence band of g-CN, forming a Z-scheme heterojunction and further improving the photocatalytic efficiency.
