Objective: To study the effect of 1,4-naphthoquinone aged black carbon (BC/1,4-NQ) on reactive oxygen species and DNA strand breaks in human bronchial epithelial cells (16HBE).
Methods: In the study, 16HBE cells were exposed to BC/1,4-NQ, BC and 1,4-NQ at the concentrations of BC/1,4-NQ (10.0/0.
Article Synopsis
- A new strain of bacteria, FJAT-13831(T), was isolated from the soil of Emperor Qin's Terra-cotta Warriors to study its classification.
- The strain's fatty acid profile suggests it belongs to the Bacillus genus, closely related to Bacillus pseudomycoides with a high genetic similarity of 99.72% in the 16S rRNA gene analysis.
- Further genetic tests revealed that FJAT-13831(T) is distinct enough to be classified as a new species, named Bacillus bingmayongensis sp. nov., with specific type strain identifiers provided.
Strain FLQ-11-1, isolated from sewage sludge, was able to degrade cyfluthrin and was identified as Lysinibacillus sphaericus based on its morphology, 16S rRNA sequence and fatty acid methyl ester (FAME) analyses. This strain could use cyfluthrin as its carbon or nitrogen source. Response surface methodology (RSM) analysis showed that the optimum conditions for degradation were at pH 7.

It was focused that the effect of C/N to nitrite accumulation and NO(2-) -N : NH(4+) -N in the effluent under the condition of 35 degrees C, dissolved oxygen(DO) 1.5-2 mg/L, hydraulic retention time (HRT) 1 day and pH 8.
