The quality of baker’s yeast products is uneven, and there is a lack of fast, accurate and cost-effective methods to evaluate its quality of baker’s yeast. The Single Cell Research Center of CAS Qingdao Institute of Bioenergy and Processes and Tianjin Agricultural College have developed a new technology for quality inspection of baker’s yeast based on single-cell Raman spectroscopy.

The team incubated baker’s yeast cells with heavy water, and quantitatively analyzed the metabolic activity and viability of individual yeast cells based on the intensity of the heavy water peak in the Raman spectrum. In addition, the trehalose content in each yeast cells was measured through Raman spectra, as an indicator for antifreeze performance. High performing strains were screened out, subjected to genome sequencing and further cultured, resulting in improved strains for the yeast industry.

A research team led by Zhang Haibo and Fu Chunxiang, researchers at the Qingdao Institute of Bioenergy and Bioprocess Technology, Chinese Academy of Sciences, in collaboration with Wang Qian, a researcher at the Tobacco Research Institute of the Chinese Academy of Agricultural Sciences, and Sang Yup Lee, a professor at the Korea Institute of Science and Technology, found that tobacco can be used as an energy crop to achieve efficient and low-carbon utilization of biomass energy and help the sustainable development of biorefining. Compared with traditional biomass raw materials, tobacco leaves have the characteristics of high water solubility, high nitrogen content and low lignocellulose content. After the tobacco leaves are sterilized with water, a liquid with comprehensive and rich nutrition and strong biocompatibility can be obtained. This liquid can be used as a culture medium directly for the cultivation of prokaryotes and eukaryotes, and can also be directly used for the biosynthesis of bio-based fuels and bio-based chemicals.

In addition, tobacco is a field crop with strong stress resistance, salt and alkali tolerance, large biomass, and easy genetic modification, and can adapt well to the environment of marginal land. Planting tobacco on marginal land is expected to produce at least 1.17×1010 Mg of tobacco leaves per year, and theoretically 2.21×1012 L of ethanol. The results of life cycle assessment show that compared with corn straw ethanol, tobacco ethanol has reduced carbon emissions by about 27% and energy consumption by about 26%. Among them, carbon emissions in the bioconversion stage have been reduced by about 76% and energy consumption has been reduced by about 81%. This study directly sterilized tobacco leaves as a culture medium, omitted two steps, improved the biorefining route, reduced carbon footprint, and laid the foundation for achieving carbon negative emissions from bioenergy utilization.

A research team from CAS QIBEBT has developed a new homogeneous cathode material, which will enable solid lithium batteries to have higher safety and superior performance, has not yet been named. It achieves over 1,000 times the electronic and ionic conductivity of traditional battery cathode materials. It can smoothly undergo charge and discharge cycles without conductive additives, which simplifies the battery preparation process and also improves the performance of the all-solid-state lithium battery.

Homogeneous cathodes were composed of 100% Li_1.75Ti₂(Ge_0.25P_0.75S_3.8Se_0.2)₃ enable room-temperature all-solid-state lithium batteries to achieve a cycle life of over 20,000 cycles at 2.5 C with a specific capacity retention of 70% and a high energy density of 390 Wh kg⁻¹ at the cell level at 0.1 C. This cathode homogenization strategy contrasts to the conventional cathode heterogeneous design, potentially improving the viability of all-solid-state lithium batteries for commercial applications.

600 kmh MAGLEV nears production in Qingdao, Shandong Province

http://Xinhua news release, July 20, 2021

Launched in October 2016, the high-speed maglev train has a designed top speed of 600 km per hour and conducted a successful test run in June 2020. According to the China Railway Rolling Stock Corporation (CRRC), a train with five carriages has been running well on a test line within the factory. The train can travel with two to 10 carriages, each holding more than 100 passengers. It is said to provide the best solution for trips within a range of 1,500 km, filling a speed gap between aviation and high-speed trains.

Qingdao’s Port is currently one of the most automated and efficient automated wharves in the world. It began its climb to the pinnacle of global port technology in 2013. In 2017, the first phase of the fully automated container terminal began operation. At the end of 2023, the Qingdao Automated Terminal was put into operation. It has progressed to full automation. As a fully automated container terminal and a “hydrogen + 5G” smart green terminal, the terminal has improved work efficiency by 30% and reduced manpower by 80%. The average loading and unloading capacity has reached 36.2 containers per hour, and the highest efficiency has reached 60.2 containers per hour

Qingdao will host China’s first hydrogen energy port

http://j.people.com.cn/n3/2024/0614/c95952-20181438.html

China’s first fully hydrogen energy port will be built in Qingdao, and the groundbreaking event was held on the 12th of June.

The Shandong Port will use Qingdao Port to establish three systems: port hydrogen supply, high-efficiency hydrogen filling, and hydrogen use safety management and control.

In addition to hydrogen energy container trucks, Qingdao Port has also introduced hydrogen energy into automated wharf applications, using hydrogen energy to power automated rail-mounted gantry cranes. In 2022, Qingdao Port completed China’s first fully qualified port hydrogen station in just three months. The station’s daily hydrogen filling capacity is more than 1,000 kilograms, and the hydrogen station’s cumulative hydrogen filling volume has exceeded 80 tons, reducing carbon emissions by more than 1,000 tons.
