Green Carbon co-organizes 17th International Clostridium Conference

http://qibebt.cas.cn/news/zyxw/202409/t20240922_7378447.html

From September 19th to 22nd, the 17th International Clostridium Conference was held in Qingdao, hosted by the International Clostridium Conference Organizing Committee, supported by the Bioenergy Research Laboratory of Qingdao Institute of Energy, the Key Laboratory of Solar Photovoltaic Conversion and Utilization, Shandong Energy Research Institute, and Qingdao New Energy Shandong Provincial Laboratory, and co-organized by the One Carbon Biotechnology Research Center and Green Carbon Editorial Department.

Since 1990, the International Clostridium Conference has been held every two years, and this Clostridium Conference is the second time to be held in China. On the afternoon of the 19th, the executive chairman of the conference, Researcher Li Fuli, director of the One Carbon Biotechnology Research Center, announced the opening of the conference. Director Lv Xuefeng delivered a speech on behalf of the Qingdao Institute of Energy and introduced the construction and development of the institute to the delegates.

This conference invited about 150 scholars and guests from domestic and foreign academic and business circles to attend the conference, including more than 50 foreign experts from Germany, the United States, France, South Korea, the United Kingdom, Italy and other countries. The conference was divided into four parts according to the topic direction: physiology and systems biology, genetics and synthetic biology, metabolic engineering and raw material utilization, industry and new applications. More than 40 oral speakers shared the latest research results with the participants, discussed future research directions, and exchanged problems and challenges encountered in Clostridium research and industrialization engineering.

As a valuable platform for scientific exchange and cooperation, this conference will further promote the development of Clostridium research. At the same time, the successful holding of this conference is of great significance to enhancing the influence of the institute in the field of Clostridium research. (Text/Photo by Ma Xiaoqing)

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.

It is the country’s largest open-access facility for in-situ coastal experiments, the IOCAS said. (IOCAS/Handout via Xinhua)

Green Carbon journal reaches impact factor 14.2 in less than 3 years

https://www.sciencedirect.com/journal/green-carbon

Green Carbon has received its first Impact Factor of 14.2 in the 2025 Journal Citation Reports (JCR) released by Clarivate on June 17, 2026. This places Green Carbon in Q1 in both the “Engineering, Chemical” category (Ranked 10/183) and the “Green & Sustainable Science & Technology” category (Ranked 8/114). Achieving this in less than three years since its launch is a testament to the journal’s academic quality, rigorous publishing standards, and growing international influence.

A deep-sea isopod uses horizontal gene transfer with a symbiotic bacterium to withstand ultra-long starvation

https://english.news.cn/20260606/de8eff009a94407c8eeeb1fdab13d675/c.html

https://www.cell.com/cell/abstract/S0092-8674(26)00571-4?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS0092867426005714%3Fshowall%3Dtrue

A joint research led by the CAS Institute of Oceanology in collaboration with the Hong Kong-based Chinese University of Hong Kong and Northwestern Polytechnical University in Xi’an deciphered the mechanism of ultra-long starvation tolerance in deep-sea isopods and provides an important paradigm for understanding how life balances growth and survival in extreme environments.

The deep sea is cold, dark, and almost entirely devoid of reliable nutrition, making long-term survival a remarkable evolutionary feat. To survive the abyss, the isopod possesses an enormous stomach that occupies about two-thirds of its body and acts like a deep-freeze pantry, allowing it to gorge when food is available and store the haul for months or even years. Second, it maintains an exceptionally low basal metabolic rate, essentially putting itself on permanent energy-saving mode. Together, these traits turn opportunistic binge eating into an ultra-long energy reserve.

In addition, a key gene involved in this metabolic slowdown, named ND1, is not originally part of the isopod’s own genome. The isopod “hijacks” it from an external symbiotic bacterium through horizontal gene transfer.

To verify ND1’s function, the researchers inserted the gene into zebrafish, nematodes, and human cells in the lab. Under normal temperatures, the gene recipients burned energy faster and became less tolerant of starvation. However, under cold conditions that mimic the isopod’s deep-sea home, ND1 suppressed energy metabolism, reduced mitochondrial activity, and boosted starvation endurance in zebrafish by a remarkable 37 percent.

This temperature-dependent switch solves the so-called “energy paradox” — how can a giant animal with high energy demands survive where food is extremely scarce? The ND1 acts as a metabolic thermostat, fine-tuning energy burn in response to environmental conditions. It provides a solution to the trade-off between body size and food scarcity.
