31-8 Anhui Province offers „carbon index service“

Carbon emissions in Anhui’s industrial sector account for about 70% of the total. As green and low carbon development of the industry is considered he most important point to achieve the goals of peaking out CO2 emissions and carbon neutrality, the province launched a carbon index system which monitors carbon emissions from four indicators of […]

26-8 CAS QIBEBT achieves high yield DHA algae through metabolic engineering

Docosahexaenoic acid (DHA, C22:6) is widely applied in pharmaceutical and food industries, and the algae Aurantiochytrium has become a representative strains for DHA production due to its high biomass and lipid content. Researchers from the CAS Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) have applied metabolic engineering strategy to prepare DHA in high purity and yield.  […]

25-8 CAS Hefei Institute of Physical Science develops Raman-based method for sensitive detection of paraquat in oily food

WANG Liangbao and colleagues at the Hefei Institute of Physical Science of the Chinese Academy of Sciences were able to use surface-enhanced Raman spectroscopy (SERS) of ethanol extracts to determine poisons in an oily matrix with high sensitivity. Using a portable Raman spectrometer, they detected paraquat and diquat in kitchen waste with a detection limit […]

24-8 Chinese team studies artificial cultivation of European black truffle

A research team at CAS Kunming Institute of Botany, Chinese Academy of Sciences has systematically analyzed the photosynthetic efficiency, nutrient uptake, inter-root carbon secretion and inter-root bacterial community of a  3-year-old Mongolian oak and its ectomycorrhizal environment. The results showed that the phosphorus uptake of Mongolian oak was significantly increased by the mycorrhiza, while the […]

23-8 Researchers at CAS Dalian Institute of Chemical Physics propose hydrogen from decoupled water electrolysis for electricity peak load regulation, using a chainmail catalyst

The group of DENG Denghui proposes a technology to balance peaks of electricity use during daytime and valleys during night time using hydrogen as a green energy carrier. To this end, they have decoupled the electrolysis of water via a Nafion membrane into an O2 evolution reaction with the reduction of a polysulfide mediator at […]

2021/08 Team at CAS Tianjin Institute of Industrial Biotechnology prepares rose fragrance using synthetic biology

The team of ZHANG Xueli has applied metabolic engineering to introduce the rose essential oil pathway into bakers’ yeast, Saccharomyces cerevisiae. To this end, they integrated the geraniol-rose alcohol synthesis module and nerol synthesis module into the same chassis strain and through optimization obtained a rose essential oil yield of up to 5 g/L in […]

16-8 China’s TanSat satellite acquires first global carbon flux data set

As the third nation after the USA and Japan, China is now monitoring global carbon dioxide emissions with the TanSat satellite. A high-resolution grating spectrometer measures CO2 and O2 absorption at three wavelengths in reflected sunlight. A large-field spectrometer is used to produce high-resolution images in five spectral regions, compensating for measurement errors due to […]
