A Raman-based strategy finds more ethanol-tolerant microbes from Baijiu fermentation

Scientists from CAS QIBEBT have developed a Raman-activated cell sorting strategy for the high-throughput discovery of ethanol-tolerant microorganisms based on their metabolic activity rather than growth.

Conventional microbial screening generally follows an “isolate first, test later” workflow, in which cells are cultivated under selective pressure, isolated, and evaluated. This approach is slow, labor-intensive and biased toward fast-growing or abundant microbes. This is important in solid-state baijiu fermentation, where rising ethanol concentrations stress microbial communities, while valuable but low-abundance active microbes are easily overlooked.

Therefore, the researchers shifted the criterion from whether a cell could grow under ethanol stress to whether it maintained active metabolism. They combined heavy-water (D₂O) labeling with single-cell Raman spectroscopy and a high-throughput Raman-activated flow cytometer known as FlowRACS. Metabolically active cells incorporate deuterium from D₂O into newly synthesized biomolecules, producing a characteristic carbon-deuterium (C-D) Raman signal. Based on this signal, the researchers derived a carbon-to-deuterium ratio (CDR) and a Raman tolerance index (RTI) to quantify the in-situ ethanol tolerance of individual cells.

The platform functionally sorted 2,400 cells per hour with an accuracy of 91.3%. One sorting round followed by culture from pit mud pretreated with 8% ethanol yielded six pure strains, all with an RTI above 50%, as opposed to only two among nine isolates from conventional agarose-plate screening. Overall, this strategy increased strain-mining efficiency 4.5-fold and phenotypic validation 7-fold, reducing the time required for key steps from days to hours.

Genomic and transcriptomic analyses revealed distinct tolerance mechanisms. Lactiplantibacillus plantarum (RTI = 85.1%) enhanced lactate dehydrogenase expression by 3.4-fold while maintaining high alcohol dehydrogenase activity, indicating adaptive redox balancing. Staphylococcus epidermidis (RTI = 62.2%) activated lipid synthesis and glycerol metabolism genes, indicating cell envelope remodeling. Both strains were rare in the original microbial community, demonstrating that function-based sorting recovers key microbes that are missed by abundance- or growth-based approaches.

The study could also be extended to acid, salt, and solvent tolerance, which would aid in building robust industrial chassis strain libraries. This work represents the latest progress of the iMAPS Consortium (in-situ Metabolic Atlas Projects @ Single-cell; www.iMAPS.info).

Gold recovery from waste liquid without chemicals

https://j.people.com.cn/n3/2026/0717/c95952-20478766.html

A new technology recovers gold from waste liquid using naturally occurring micro-droplets at the oil-water interface, simply by moderately heating the oil-water system—without the addition of any reducing agents, adsorbents, or catalysts.

The technology was developed by a team from the China University of Petroleum in Qingdao, in collaboration with researchers from Stanford University.

Drawing on their previous research into geological fluids—where they discovered that large numbers of chemically active micro-droplets are generated at oil-water interfaces under high-temperature conditions—the team formulated a bold hypothesis: “Could we selectively extract gold from complex waste liquids simply by utilizing the chemical properties of these micro-droplets?”

To test this, the team constructed a heat-driven oil-water interfacial reaction system. Moderate heating causes the continuous formation of micro-droplets (5–50 micrometers in diameter) at the oil-water interface. These droplets function like micro-reactors with high redox activity, continuously generating active species such as highly active electrons, hydrogen radicals, and hydroxyl radicals. This process enables the reduction of gold ions in the solution to elemental gold without the need for external reducing agents, catalysts, or adsorbents; furthermore, the coalescence and growth of these micro-droplets allow for the formation of millimeter-sized gold particles.

The study also elucidated the chemical mechanism by which the interfacial micro-droplets selectively recover gold. Experiments demonstrated gold recovery rates of 98.5% from complex aqua regia waste liquid and 97.0% from electronic waste leachate. The recovery time was further reduced through heating and cooling cycles, and a recovery efficiency of over 90% was maintained even when the oil phase was reused. In a scale-up experiment, 500 milliliters of gold-containing leachate were processed to yield 0.5657 grams of solid product. The gold achieved a purity of 99.4%, demonstrating high potential for application as an environmentally friendly technology for recovering precious metals from complex acidic wastewater.

An offshore platform for coastal ecosystem research near Qingdao

https://en.people.cn/n3/2026/0711/c90000-20476703.html

China put into operation a large offshore platform for controlled in-situ experiments regarding coastal ecosystems. Developed by the CAS Institute of Oceanology (IOCAS), the facility is deployed in the Yellow Sea off Rongcheng in Shandong Province.

With a total area of 2,000 square meters and an experimental sea zone of 30,000 square meters, the platform is designed to support a wide range of ecological studies under real marine conditions. Under real seawater conditions, key factors such as temperature, nutrients and dissolved oxygen can be precisely regulated, enabling continuous, full-cycle observation and breaking the technical barrier between natural-sea observation and indoor controlled experiments.

The platform comprises modules for automated monitoring, water regulation, mesocosm ecosystems and logistics support. It enables precise single-factor or multi-factor regulation of temperature, nutrients, dissolved oxygen and other variables, allowing researchers to reproduce scenarios like ocean warming, acidification and eutrophication in a real marine environment. This capability is crucial for understanding how coastal ecosystems respond to both gradual climate trends and extreme events.

China’s coastal waters, where most marine economic activities and ports are concentrated, are hotspots for ecological disasters and risks. These waters, notably, are under mounting stress from climate change, land-based inputs and human activities. The new lab is located in a typical mariculture area of northern China, offering conditions for both natural and farmed ecosystem studies. Researchers can conduct scenario experiments on carrying capacity, ecological resilience, marine heatwaves and hypoxia to identify risk thresholds and optimize aquaculture management. Beyond serving the aquaculture industry, it can provide technical support for disaster prevention, precision restoration and coastal health management, said Sun.

The platform is designed for open international collaboration and will be made available to global research institutions, facilitating joint efforts to tackle pressing marine environmental challenges.
