China eager to step up gene sequencing technology

In a review on gene sequencing patents issued in China, the authors have identified 448 gene sequencing patent portfolios of which US-based companies have generated 249, followed by Japan (48), the Netherlands (28), UK (22), Switzerland (18) and Germany (13). The leading Chinese companies are Shenzen’s BGI, followed by Guangdong’s Surexam Biotechnology Co. and Beijing’s […]

CAS Hefei Institute of Technical Biology and Agriculture Engineering develops sunlight-sensitive catalyst to degrade glyphosate

The group of WU Zhengyan has developed a KMnO4 /graphite composite catalyst using high energy electron beam irradiation which reduced MnO4- to MnO2 in graphite nanospheres. The resulting MnO2/C composite possessed high catalytic degradation efficiency for glyphosate under sunlight due to its high porosity, large specific surface area, and its large number of active sites […]

CAS Shanghai Institute of Organic Chemistry elucidates biosynthetic pathway of lincosamide antibiotics

Lincosamides are clinically important glycoside antibiotics for the treatment of infections from Gram-positive pathogens. The group of Wen LIU has clarified the mechanism by which lincomycin A can be transformed into a number of active derivatives which, by the use of synthetic biology, might lead to improved manufacturing processes.

Chongqings Bio-Pharmaceutical Co. is China’s largest specialist for porcine islet xenotransplantation

The company has mastered the whole industrial chain of preparing human insulin in pathogen-free transgenic pigs and achieving large-scale extraction of the porcine islets. Clinical studies on diabetic patients will be completed in January 2017. The company works also on xenotransplantation of porcine islets, and it is expected that 5 patients will undergo surgery in […]

CAS QIBEBT develops efficient microalgae recovery technology using electrolytic flotation

The procedure is based on micro air bubbles generated by graphite electrodes through electrolysis of water. Diameter of the highly uniform air bubbles is just 1-3 μm, leading to recovery of, e. g., Chlorella up to 95% by flotation. For 1 kg of harvested algae (dry weight), electrolytic flotation consumed only 0.03kWh. At present, QIBEBT’s […]

CAS QIBEBT team applies genome editing to microalgae

The group of Jian XU and colleagues at the Single Cell Center of QIBEBT has established a CRISPR/Cas9-based precise genome editing approach for the oleaginous microalga Nannochloropsis oceanica, using the deletion of nitrate reductase (NR; g7988) as example. Mutants where screened by the institute’s Raman-based FACS sorter. CAS news release, August 23, 2016
