This study aimed to investigate the ability for decolorizing and detoxifying of malachite green (MG), methyl violet (MV), crystal violet (CV), and cotton blue (CB) by endophytic fungi under oligotrophic conditions. Isolate SWUNF9, was identified as <i>Colletotrichum graminicola</i>, which is the most promising for the four TPM dyes removal. Our findings revealed that the decolorization efficiency of isolate SWUNF9 for MG with 91% was significantly higher than other TPM dyes. The change of UV–vis peaks further suggested degradation and sorption of TPM dyes chromophores by isolating SWUNF9. Furthermore, the optimization result demonstrated the decolorization rate of four TPM dyes by isolating SWUNF9 under oligotrophic conditions could reach above 92% at 24 h. We showed that the detoxifying of TPM dyes was caused by biosorption and degradation of <i>C. graminicola</i> SWUNF9, respectively. Moreover, phytotoxicity tests confirmed the lower significant toxicity toward the test seeds (<i>Vigna radiata</i> and <i>Zea mays</i>) of the treatment by isolating SWUNF9 when compared to dyes before treatment. The above studies indicate that isolate SWUNF9 could be used as a potential TPM dyes adsorption and degradation agent, and enhances our understanding of endophytic <i>C. graminicola</i> (SWUNF9) as a promising tool for dye removal treatment of colored textile effluents.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 1","pages":""},"PeriodicalIF":3.8,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142790403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

MPs were characterized using ATR-FTIR spectroscopy, stereomicroscopy, and SEM–EDX analysis. The agricultural soils were categorized into 5–2 mm, 2–1 mm, and 1–0.5 mm size fractions, concentrating on MPs less than 5 mm in surface waters. The mean abundance of MPs in surface soils was 2800 ± 696.42, 2320 ± 622.09, and 2040 ± 313.05 particles/kg, while in subsurface soil they were 2680 ± 576.19, 2200 ± 570.09, and 1760 ± 443.72 particles/kg for respective size fractions, and 376 ± 57.29 particles/liter in surface water. MPs were significantly correlated with soil moisture, pH, electrical conductivity, organic matter, nitrogen, and phosphorus. The predominant polymers were polyethylene, polypropylene, and polystyrene, mainly in fiber and film forms. The ecological risk evaluation indicated a high risk for surface soil and a medium-to-high risk for subsurface soil of agricultural land and surface water. Plastic mulch, solid waste, surface water irrigation, and organic compost were probably the potential sources of MPs, and their entrance into farmland and adjacent environments should be strictly limited.
