All‐Round Talent: Unique Zinc Guanidine Catalyst Performs Efficiently in Synthesis and Chemical Recycling of (Bio)Polyesters

open access: yesAdvanced Science, EarlyView.
A new zinc hybrid guanidine catalyst [Zn{(R,R)TMGNMe2(1,2)ch}2](OTf)2 (C1) shows very high catalytic activity in the polymerization of cyclic esters and in the depolymerization of these polyesters. Using C1 in the ring‐opening polymerization of lactide and caprolactone under industrially relevant conditions, astonishing rate constants of the same order

Food Technologies: Fermentation

open access: yes, 2014
Fermentation refers to the use of microorganisms to achieve desirable food properties in the fermented food or beverage. Although the word ‘fermentation’ indicates ‘anaerobic metabolism,’ it is also used in a broader sense to indicate all anaerobic and aerobic microbiological and biochemical modifications that result in desirable quality modifications ...

CRISPR‐DNA Polymerase Assisted Targeted Mutagenesis for Regulable Laboratory Evolution

open access: yesAdvanced Science, EarlyView.
This study develops an in vivo targeted mutagenesis system based on CRISPR‐guided bacteriophage T5 or T7 DNA polymerases. This system can enable all possible types of substitution mutations within an expanded mutagenesis window in Escherichia coli and exhibit application potential in different microorganisms, thus accelerating the evolution of ...

Photobiomodulation Strengthens Muscles via Its Dual Functions in Gut Microbiota

open access: yesAdvanced Science, EarlyView.
Non‐invasive photobiomodulation therapy (PBMT) enhances muscle endurance by rewiring the gut‐muscle axis. PBMT preserves gut epithelial integrity and enriches beneficial anaerobes, driving metabolites such as butyrate, spermidine, and L‐carnitine that supercharge mitochondrial energy in skeletal muscles.

Alkaline–Acid Intestine Environment Controlled by A Carbonic Anhydrase Gene Influences Synthesis of Sex Pheromone by Symbionts

open access: yesAdvanced Science, EarlyView.
A model proposing that elevated rectal expression of CAh1 in males alkalinizes the environment to regulate Bacillus production of a male‐specific sex pheromone. Abstract The intricate interplay between animals and their intestinal microbes is pivotal in shaping various aspects of animal biology.

Nanoparticle‐Functionalized Cellulose Through Biosynthesis‐Only Approach

open access: yesAdvanced Science, EarlyView.
This study reports the first covalent incorporation of glucose‐modified carbon dots (Glu‐CDs) into bacterial cellulose (BC) via microbial fermentation, resulting in BC nanofibers that exhibit uniform cyan fluorescence. A 3D‐printable hydrogel (Glu‐CDs‐BC‐SA) is developed, facilitating the fabrication of fluorescent structures. This work demonstrates an
