However, only a few studies have been conducted on the influence of ofloxacin (OFL) on the production of short-chain fatty acids (SCFAs) and its underlying mechanisms during WAS anaerobic fermentation. This study aimed to elucidate the impact of OFL on SCFA production from alkaline-pretreated WAS fermentation. The results showed that the addition of 10 mg OFL/kg SS led to a peak concentration of 2931.85 mg COD/L, resulting in a 1.1-fold increase in SCFA production compared to the control group. Further exploration revealed that OFL simultaneously promoted WAS solubilization, hydrolysis and acidification. Additionally, a low concentration of OFL increased the abundance of hydrolytic acidifying bacteria but decreased the abundance of SCFA-consuming bacteria. Metagenomic analysis revealed an enhanced abundance (103.76–134.56%) of critical genes related to extracellular hydrolysis (i.e., <em>malZ</em>, <em>bglX</em>, and <em>degP</em>), membrane transport (i.e., <em>msmX</em>, <em>gtsA</em>, and <em>gltI</em>), substrate metabolism (i.e., <em>glk</em>, <em>glnA</em>, and <em>gdhA</em>), and SCFAs biosynthesis (i.e., <em>ackA</em> and <em>fabG</em>) in the presence of low OFL concentration. These findings broadened our understanding regarding the influence exerted by OFL on WAS anaerobic fermentation.</div></div>","PeriodicalId":13643,"journal":{"name":"International Biodeterioration & Biodegradation","volume":"198 ","pages":"Article 106013"},"PeriodicalIF":4.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143165386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biomass and metabolic processes were monitored by measuring the time-dependent biophysicochemical parameters and with Fe⁰ (steel) as the sole electron source, or with H₂ as control. Although yields and sulfate reduction rates were higher with H₂ due to its greater bioavailability, the yield coefficients indicated that bacterial growth with Fe⁰ was equally efficient. Upon imaging of the steel surface by SEM, patches of cells embedded in an iron sulfide matrix on top of larger carbonate and phosphate minerals were observed. Cell number determination indicated that the cells on the steel surface constituted only a minor proportion (&lt;4%) of the total counts. The 16S rRNA gene sequencing revealed the enrichment of sulfate reducers next to acetogens, indicating a syntrophic relationship. In compliance with biophysicochemical analysis and estimated yield coefficients, metaproteomics indicated no major differences in the pathways of energy metabolism between treatments with H₂ and Fe⁰. Highly abundant proteins namely periplasmic hydrogenases and c-cytochromes associated with H₂-mediated electron transfer coupled to dissimilatory sulfate reduction indicated this mechanism to be dominant (except for a few putative outer membrane proteins identified with Fe⁰).

The interactions between cyanide and phenol during biodegradation were investigated. It was found that the presence of 100 mg/L cyanide significantly enhanced the degradation of phenol, leading to the complete degradation of 1000 mg/L phenol within 86 h.

Additionally, the presence of phenol had minimal impact on cyanide degradation; a concentration of 100 mg/L cyanide could be rapidly and completely degraded within 40 min even in the presence of up to 1000 mg/L phenol. Five empirical kinetic models of Haldane, Aiba, Edward, Yano, and Webb were employed to describe the degradation processes of phenol and cyanide in both single-substrate and dual-substrate systems.

This strain was immobilized on a biodegradable carrier – a cellulose sponge from <em>Luffa cylindrica</em>. The study aimed to determine the impact of the immobilization process on the metabolic activity of the strain, including the biodegradation process of paracetamol. The research that was conducted showed significant differences in the level of transcription of selected genes, as well as in the metabolic profile and the composition of total fatty acids. However, the immobilization process did not significantly affect the degradation of paracetamol. This indicates a lack of limitation in the availability of the substrate, which is not very toxic to the tested strain. However, immobilization causes greater strain resistance to the appearance of the toxic 4-aminophenol. After immobilization, it is possible to decompose higher concentrations of paracetamol, which, under normal conditions, leads to the accumulation of 4-aminophenol, inhibiting the free strain's growth. Differences in the degradation of this drug by free and immobilized cells, depending on the number of doses, were observed. After analyzing the enzymes and intermediates of the paracetamol degradation pathway, differences were shown between the metabolism of this compound by the free and immobilized strain. It was shown that, 3-methyl-3-vinyl-cyclohexanon was a characteristic intermediate identified only during paracetamol degradation by the free strain of KB4.
