Chao Yang, Wenjun Sun, Xiuwei Ao

Frontiers of Environmental Science & Engineering 2020, Volume 14, Issue 1, doi: 10.1007/s11783-019-1192-6

Abstract: • Long amplicon is more effective to test DNA damage induced by UV. • ATP in bacteria does not degradeWe used quantitative polymerase chain reaction (qPCR) to investigate DNA damage and evaluated adenosineThe results of qPCR effectively showed the DNA damage induced by UV when using longer gene amplicons,in that sufficiently long amplicons of both 16S and gadA indicated that the UV induced DNA damages.

Ball milling promoted direct liquefaction of lignocellulosic biomass in supercritical ethanol

Chunyan Yang, Xiaoliang Yuan, Xueting Wang, Kejing Wu, Yingying Liu, Changjun Liu, Houfang Lu, Bin Liang

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 4,   Pages 605-613 doi: 10.1007/s11705-019-1841-0

Abstract: In the present work, ball milling was applied for the pretreatment of lignocellulose to obtain high conversion and bio-oil yield in supercritical ethanol. Ball milling substantially decreased the crystallinity and particle size of lignocellulose, thereby improving its accessibility in ethanol solvent. An increased bio-oil yield of 59.2% was obtained for the ball milled camphorwood sawdust at 300°C, compared with 39.6% for the original lignocellulose. Decreased crystallinity significantly benefited the conversion of the cellulose component from 60.8% to 91.7%, and decreased particle size was beneficial for the conversion of all components. The obtained bio-oil had a high phenolic content, as analyzed by gas chromatography-mass spectrometry. Methoxylation and retro-aldol condensation were observed during alcoholysis, and the reaction pathways of lignocellulose in supercritical ethanol were attributed to the action of free radicals.
