Reporting in the Journal of Bioresources and Bioproducts, a China-led team cultivated the cellulose-secreting bacterium Taonella mepensis inside thin silicone tubes, producing hollow hydrogel cylinders of extraordinary purity. After a 30 % strain twist and overnight drying, the resulting fibers reached 1.06 GPa tensile strength—higher than any previously reported bacterial-cellulose thread—while remaining light enough to lift 342,000 times their own mass. Exposure to water vapor triggers a rapid untwisting motion that peaks at 884 revolutions per minute per metre, a speed unmatched by existing biopolymer actuators. No synthetic additives are required; the response emerges from reversible hydrogen-bond rearrangement between nanofibrils. Stored fibers retain 86 % of their rotational speed after eight months, and prototypes already function as remote rain sensors, on–off switches and self-opening curtains. The work, supported by China’s National Key R&D Program, points toward low-carbon, biodegradable hardware for soft robotics and environmental monitoring.

Engineers have merged neomycin-grafted cellulose nonwovens with a polyvinyl-alcohol/cellulose-nanofiber aerogel to create a biodegradable smart bandage that delivers >99 % kill of Staphylococcus aureus and Escherichia coli within 30 min, scavenges 93 % of free radicals and produces –1.4 mmHg micro-negative pressure to pull exudate away from chronic lesions. Reporting in the Journal of Bioresources and Bioproducts (2025, 10, 373-385) the team show that blueberry-derived anthocyanins embedded in the matrix act as a built-in pH sensor, shifting colour when infection drives wound alkalinity above pH 8. In a murine full-thickness infection model the dressing closed 88 % of wound area in seven days, outperforming a leading commercial dressing and suppressing inflammatory IL-1β and TNF-α expression to baseline levels. Complete soil burial disintegrates the device within 90 days, offering a plastic-free route to connected wound care.

An international team has quantified furan fatty acid (FuFA) across 48 rubber-tree genotypes planted in Cambodia, recording concentrations from 0.01 % to 0.71 % of latex weight and single-tree yields up to 2 446 mg per cut. Published in the Journal of Bioresources and Bioproducts (2025, 10, 111-122), the work links high FuFA levels to increased total fatty-acid pools and identifies palmitoleic acid as a new biochemical marker. With broad-sense heritability estimated at 93 %, breeders can select parent PB5/51 to amplify the trait, offering growers a lucrative side-stream from existing plantations without extra land or fertilizer.

The latest issue of Journal of Bioresources and Bioproducts (2025, 10, 295-309) surveys four millennia of cellulose sutures and concludes that newly engineered nanocellulose and oxidized regenerated cellulose fibers lose more than half their tensile strength in only seven days—fast enough to qualify as absorbable under ISO standards. The Chinese–Iranian team behind the survey demonstrates wet-spun cellulose nanofibril (CNF) threads reaching 1 877 MPa when blended with chitosan, while interfacial polyelectrolyte complexation (IPC) embeds antibiotics or growth factors directly into the filament core. In vivo rodent data reveal smaller inflammatory footprints and 1.7-fold higher collagen deposition than silk or Vicryl controls, suggesting the plant-based threads could soon move from bench to bedside.

Reporting in the Journal of Bioresources and Bioproducts, researchers outline a closed-loop concept: a glutaraldehyde-cross-linked chitosan/carboxymethyl-cellulose sponge first adsorbs Cr³⁺, Al³⁺ and Zr⁴⁺ from simulated tannery liquor at pH 4, obeying Langmuir kinetics. Instead of conventional acid desorption, the metal-laden gel is simply swollen, sheared and added to the re-tanning bath where its wide-molecular-weight fragments and coordinated metals raise shrinkage temperature by up to 8 °C and increase tear strength 40 %. The tactic eliminates a disposal step while cutting virgin chrome demand.

Writing in the Journal of Bioresources and Bioproducts, researchers unveil the first short-term dynamic model that couples Monod and Haldane kinetics to simulate day-and-night carbon switching by Chlorella vulgaris in anaerobic-digestion wastewater. Dubbed ADBA, the framework needs only 25 parameters yet predicts biomass, dissolved gases and nitrogen removal under variable light, turbidity and bacterial load. Calibration with five culture scenarios achieved R² = 0.90, offering designers a lightweight alternative to earlier 100-plus-parameter platforms. Simulations indicate that keeping effluent turbidity below 0.5 AU and ammonium between 100–1 000 mg L⁻¹ can double productivity, suggesting low-cost pre-treatment routes for on-farm algae reactors.

Writing in the Journal of Bioresources and Bioproducts, a Chinese–industry team describe an industrial-scale route for spirally winding 0.3 mm bamboo veneers into 8–12 mm drinking straws. Steam-softened, flattened Moso bamboo is ultrasound-cleaned to remove colourants and starch, eliminating mould risk, then bonded with food-grade water-borne polyurethane. The resulting straws deliver compression (≈17 MPa) and bending (≈14 MPa) strengths that match premium paper straws yet absorb 60 % less liquid; 1 500-consumer blind tests ranked them first over paper and PLA. Life-cycle screening indicates 70 % lower CO₂ footprint than polypropylene.

Published in the Journal of Bioresources and Bioproducts, a new review synthesizes two decades of global research on turning agricultural leftovers into dissolving pulp for viscose, lyocell, and other regenerated cellulose textiles. Soybean straw, wheat straw, rice straw, sorghum stalks, and sugarcane bagasse—currently burned or left to rot—emerge as technically viable feedstocks that match the purity and reactivity of conventional wood pulp while slashing land-use pressure and greenhouse-gas emissions. The authors urge industry to pilot region-specific biorefineries and to complete full life-cycle assessments before scaling.

This study uncovers a new molecular mechanism by which the E3 ubiquitin ligase PIAS4 orchestrates pluripotency exit and lineage commitment in porcine embryonic stem cells (pESCs). Using a genome-wide CRISPR screening approach, the researchers identified PIAS4 as a critical regulator that modulates histone H3K4me3 marks via SUMOylation-mediated stabilization of KDM5B. Loss of PIAS4 impaired stem cell differentiation, disrupted lineage specific gene programs, and altered mesendoderm specification through LEFTY2–SMAD signaling. These findings not only provide fundamental insight into porcine stem cell biology but also pave the way for applications in livestock breeding, artificial meat production, and regenerative medicine.

This study developed a metal-drug self-delivery nanomedicine (FDAH) to enhance chemotherapy/chemodynamic therapy for hepatocellular carcinoma (HCC). Leveraging a core of iron-based nanoparticles co-loaded with two clinical drugs, Doxorubicin (DOX) and Plerixafor (AMD3100), and an outer shell of hyaluronic acid (HA), the system enables targeted drug delivery and combats therapeutic resistance. After intravenous administration, the HA shell prolongs blood circulation, facilitating tumor accumulation via the EPR effect and subsequent cellular uptake through HA/CD44-specific interactions. Inside tumor cells, the iron ions mediate chemodynamic therapy by triggering the Fenton reaction to generate reactive oxygen species (ROS), which disrupts redox homeostasis and sensitizes cells to DOX. Simultaneously, AMD3100 blocks the CXCL12/CXCR4 axis to alleviate immunosuppression and enhance chemotherapeutic efficacy. This work demonstrates that targeting the immunosuppressive microenvironment with a CXCR4-inhibiting nanoplatform can effectively synergize chemotherapy and chemodynamic therapy for improved HCC treatment.
