Simultaneous removal characteristics of ammonium and phenol by Alcaligenes faecalis strain WY-01 with the addition of acetate

Didecyldimethylammonium Chloride- and Polyhexamethylene Guanidine-Resistant Bacteria Isolated from Fecal Sludge and Their Potential Use in Biological Products for the Detoxification of Biocide-Contaminated Wastewater Prior to Conventional Biological Treatment

“…Furthermore, apparently, the decomposition of toxic substances could be caused by the activity of A. faecalis , which are known for their ability to degrade various biocides. In particular, A. faecalis WY-01 can simultaneously remove phenol and ammonium, which can be used to treat specific wastewater containing these pollutants [ 59 ]. The genome of A. faecalis subsp.…”

Low-temperature phenol-degrading microbial agent: construction and mechanism

“…When the carbon source with COD equivalent of 200 mg L -1 was added, the phenol degradation rate of the experimental group with glucose and sodium citrate as co-metabolized substrates was signi cantly faster than the other experimental groups, and the phenol was completely degraded within 36 h. The degradation rate of the experimental group with glucose as co-metabolized substrate was slightly faster than that of sodium citrate, which may be that glucose is the preferred substrate for biodegradable phenol, resulting in a faster growth rate and higher biomass yield (Shen, et al, 2009). The degradation rate of the experimental group with methanol as the co-metabolized carbon source was not as good as the control group in the rst 24 h. The reason for this is that due to the biological toxicity of methanol, the addition of methanol requires a certain adaptation period before the effect of methanol can be fully exploited, which is re ected in the degradation process after 24 h. The experimental group with the addition of sodium acetate as the co-metabolized carbon source substrate was able to degrade phenol completely within 48 h, but its degradation rate was lower than the other four groups (including the control group), probably because the low-temperature phenol-degrading strains preferentially used sodium acetate rather than phenol as the growth carbon source, and no co-metabolism system was formed between the two (Chen, et al, 2021). The degradation rate of phenol became signi cantly faster after 36 h until complete degradation.…”
