Printing and dyeing wastewater with high content of organic matters, high colority, and poor biochemical performance is hard to be degraded. In this study, we isolated viable but non-culturable (VBNC) bacteria from printing and dyeing wastewater with the culture media contained resuscitation promoting factor (Rpf) protein secreted by Micrococcus luteus, counted the culturable cells number with the most probable number, sequenced 16S rRNA genes, and performed polymerase chain reaction-denaturing gradient gel electrophoresis. It is obviously that the addition of Rpf in the enrichment culture could promote growth and resuscitation of bacteria in VBNC state to obtain more fastidious bacteria significantly.

- Catechol and nitrite in drinking water can lead to the formation of harmful halonitromethanes (HNMs) during chlorination, but the influence of metal ions is not well understood.
- The study specifically looked at how metal ions (Fe, Ti, Al) affect the formation of trichloronitromethane (TCNM), a key HNM, through chlorination of catechol and nitrite.
- Results indicate that metal ions enhance TCNM formation, with iron being the most effective, and that this process is more favorable in basic pH conditions (8-9) than in acidic or neutral ones.
