Biofuel production from lignocellulose feedstocks is sustainable and environmentally friendly. However, the lignocellulosic pretreatment could produce fermentation inhibitors causing multiple stresses and low yield. Therefore, the engineering construction of highly resistant microorganisms is greatly significant.

The lead (Pb) contamination is considered a lethal threat to birds. However, Pb-induced hepatotoxicology especially its impacts on metabolic processes in the liver of birds is not yet fully understood. Therefore, we tried to determine the toxicological effects of Pb exposure on hepatic carbohydrate and lipid metabolism via Phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) pathway by using an animal model- Japanese quail (Coturnix japonica).

Crystal structure of Rb[BO(OH)]·2HO.

Acta Crystallogr E Crystallogr Commun

October 2022

Beijing Chaoyang Foreign Language School, Beijing 100101, People's Republic of China.

The solvothermal reaction of HBO, sodium -butoxide, RbCO and pyridine led to a new alkaline metal borate hexa-rubidium hexa-hydroxy-dodeca-borate dihydrate, Rb[BO(OH)]·2HO. Its structure contains a large cyclic dodeca-oxoboron cluster, [BO(OH)], formed by six {BO} rings. In the crystal, O-H⋯O hydrogen bonds between the components lead to the formation of a three-dimensional supra-molecular framework.

Crystal structure of 4,4'-(diazenediyl)dipyridinium nitrate perchlorate.

Acta Crystallogr E Crystallogr Commun

September 2022

School of Science, China University of Geosciences, Beijing 100083, People's Republic of China.

The title compound, CHN ·NO ·ClO , was obtained unexpectedly by the reaction of Co(ClO)·6HO and cytidine-5'-monophosphate with 4,4'-azo-pyridine in an aqueous solution of nitric acid. The mol-ecular structure comprises two planar 4,4'-diazenediyldipyridinium dications lying on inversion centres and perchlorate and nitrate anions in general positions. In the crystal, N-H⋯O hydrogen bonds between dications and anions lead to the formation of [232] chains.

This study explored the regulation of photosystem and central carbon metabolism in cell growth and fucoxanthin accumulation of Isochrysis zhangjiangensis via transcriptome analysis, targeted metabolite measurements, and flux balance analysis. High light promoted biomass accumulation but dramatically decreased fucoxanthin productivity. It suppressed the active photosystem and reduced chlorophyll content, but improved metabolic flux of Calvin-Benson-Bassham and tricarboxylic acid cycle for massive biomass accumulation.
