Bacteria cells are so small that it has been very difficult until now to analyze the genetic code and metabolic activity of just one cell. Instead, large groups of bacteria have to be analyzed at the same time. But a new screening technique using optical tweezers and taking advantage of the properties of gravity is letting researchers analyze bacteria cells one by one. The new findings have been published in the journal SMALL by Wiley-VCH on June 9.

Recently, a research team led by Prof. YANG Yong from Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), has developed a simple, economical and efficient high-temperature pyrolysis synthetic method.
Using environmentally friendly biochar and inexpensive Cu (NO3)2 as the raw materials without post-treatment process, scientists have synthesized the atomic dispersed Cu-N-C catalyst. The atomic dispersion of coordinatively unsaturated Cu-N2 sites is on biomass-derived hierarchically N-doped porous carbon with high specific surface area. The loading content of N and Cu in the catalyst (labeled as Cu1/NC-800) was 5.44 and 1.28 wt % respectively.
Non-noble metal nitrogen doped carbon material (M-N-C) catalysts are considered as potential alternatives for precious metals, due to their abundance, biocompatibility, environmental benign and high catalytic performance.
However, the current ...

Cells are a little easier to understand, thanks to improved technology developed by a team of researchers based in China. Using a method called Raman-Activated Cell Ejection and Sequencing (RACE-Seq), the scientists were able to greatly improve the success of identifying and sequencing individual cells from our environments to understand the cells’ functions. They published their results recently in Analytical Chemistry. Cells are a little easier to understand, thanks to improved technology developed by a team of researchers based in China.

Acetylacetone is not a naturally occurring metabolite, however, it can be catabolized by Acinetobacter johnsonii as a carbon source. Inspired by the biodegradation pathway, the QIBEBT researchers established a biosynthetic pathway of acetylacetone from fermentable sugars. And the acetylacetone was successfully produced by engineered Escherichia coli by key enzyme screening and cultivation condition regulation. Acetylacetone is widely used as fuel additive and dyeing intermediate. It is also applied in the fields of metal extraction, metal plating, and resin modification. Traditionally, acetylacetone is manufactured through chemical routes using acetone ...

Researchers from Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) proposed a new mechanism to improve the yield of terpene compounds synthesized by biological methods. Terpenes are widely used in medicine, food additives, cosmetics, biological control, energy industry and many other fields. Recent years, terpenes have attracted more and more attentions due to the high energy density, low freezing point, and low ...
