Spatial Control of Light‐Responsive Proteins and Optogenetics Within Hydrogels via Volumetric Bioprinting

Advanced Materials, Volume 38, Issue 60, 27 October 2026.
Spatiotemporal control over cell behavior within bioprinted constructs remains a key challenge in biofabrication. Volumetric bioprinting using multi‐wavelength light sources permits to activate light‐sensitive intracellular proteins as well as optogenetic gene and protein expression circuits in bioprinted cells, in addition to enabling fast printing of

A purple non-sulfur bacterium producing polyhydroxybutyrate and the conserved region of pha synthase gene

Bioscience Journal, 2016
This study aimed to screen purple non-sulfur bacteria capable of accumulating granules or polyhydroxybutyrate (PHB) inside the cells, identify the potent strain, assay the enzyme or PHA synthase, and compare the PHB synthase gene with that of related ...

Light‐Driven Butyrate Production by a Probiotic Clostridium tyrobutyricum Enabled by a Cell‐Semiconductor Hybrid Interface

Food Chemistry International, Volume 2, Issue 3, Page 388-397, September 2026.
This schematic illustrates a light‐driven biohybrid system where CdS nanoparticles, mineralized on the probiotic Clostridium tyrobutyricum, inject photoelectrons to elevate intracellular NADH. This boosts the flux through key NADH‐dependent enzymes (GapA, Hbd, and Bcd), reprogramming metabolism to enhance butyrate yield by 33.2% and selectivity to 95.7%

Preparation Method of Compost Tea Affects Its Suppression of Grey Mould (Botrytis cinerea) of Tomato Plants

Plant Pathology, Volume 75, Issue 5, September‐October 2026.
Compost teas were prepared from different sources and dilution factors and used to treat tomato plants infected with Botrytis cinerea (grey mould disease). The treatments showed variable disease control efficacy, which was found to be related to differential bacterial and fungal community composition in the different compost teas.

Two Distinct Aerobic Methionine Salvage Pathways Generate Volatile Methanethiol in Rhodopseudomonas palustris

mBio, 2018
5′-Methyl-thioadenosine (MTA) is a dead-end, sulfur-containing metabolite and cellular inhibitor that arises from S-adenosyl-l-methionine-dependent reactions.

Enhancement of photo-driven biomethanation under visible light by nano-engineering of Rhodopseudomonas palustris

Bioresources and Bioprocessing, 2021
Biomethanation is of great interest as it can transform CO2 to methane under ambient conditions. In particular, genetically engineered bacterium of Rhodopseudomonas palustris showed great promise for one-step biomethanation powered by solar energy, which

Interaction Among Microbiota, Chemical Composition, and Quality Variations in Coffea arabica Across Altitudinal Gradients During Wet Processing

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Fermentation significantly altered the dominant bacterial genera from Sphingomonas and Pleomorphomonas (before fermentation) to Weissella and Lactobacillus (after fermentation), while Cladosporium and Fusarium remained the dominant fungal genera. Notably, non‐volatile compounds in de‐pulping coffee beans and volatile compounds of roasted coffee beans ...

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3

The FEBS Journal, Volume 293, Issue 15, Page 4724-4743, August 2026.
Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

Efficient Culture of Rhodopseudomonas palustris Using Landfill Leachate

Journal of Pure and Applied Microbiology, 2018
The efficient culture of Rhodopseudomonas palustris using landfill leachate was investigated. Total organic carbon (TOC) and total nitrogen (TN) in landfill leachate were 16.0 g/L and 1.1 g/L at pH 4.5, respectively, which was apparently reduced with ...

Ribosome Purification from an α-proteobacterium and rRNA Analysis by Northern Blot

Bio-Protocol, 2020
Ribosomes are an integral part of cellular life. They are complex molecular machines consisting of multiple ribosomal proteins and RNAs. To study different aspects of ribosome composition, many methods have been developed over the decades.
