Bioaugmentation of activated sludge by an indigenous 3-chloroaniline-degrading Comamonas testosteroni strain, I2gfp.
A strain identified as Comamonas testosteroni I2 was isolated from activated sludge and found to be able to mineralize 3-chloroaniline (3-CA). During the mineralization, a yellow intermediate accumulated temporarily, due to the distal meta-cleavage of chlorocatechol. This strain was tested for its ability to clean wastewater containing 3-CA upon inoculation into activated sludge. To monitor its...
متن کاملIsolation and Identification of Anionic Surfactant Degrading Bacteria from Activated Sludge
Linear alkylbenzene sulfonate (LABS) is an anionic surfactant widely used all over the world. They will eventually end-up and accumulate in household or industrial sewage. Due to their high foaming capabilities which can cause numerous problems in sewage treatment facilities as well as direct toxic effects on many different organisms in ecosystem they are generally considered as serious polluta...
متن کاملAcute sensitivity of activated sludge bacteria to erythromycin.
The presence of antibiotics in water resources has been disturbing news for the stakeholders who are responsible for public health and the drinking water supply. In many cases, biological wastewater treatment plants are the final opportunity in the water cycle to trap these substances. The sensitivity of activated sludge bacteria to erythromycin, a macrolide widely used in human medicine was in...
متن کاملScreening and Fermentation Characteristics of PHA Bacteria in Activated Sludge
Using sludge at the bottom of Hengshui Lake as samples, and screened out the SJ-9 strain with PHA synthesis capability by enrichment, purification, Nile blue staining, far-infrared spectroscopy and gas qualitative and quantitative analysis. The infrared scanning of SJ-9 bacteria product showed that this product was middle chain PHA. Optimization of SJ-9 fermentation conditions obtained the opti...
متن کاملIsolation of floc-producing bacteria from activated sludge.
Although the activated sludge process for stabilizing liquid organic wastes is primarily a biological process, very little research has been conducted on the pure biological phases of this process. Until the work of Butterfield (1935), activated sludge was considered by some as a physio-chemical process and by others as a bio-chemical process. Butterfield isolated a bacterium, Zoogloea ramigera...
