Microbial remediation is an effective method for removing thin oil slick contamination. In this study, the adsorption and degradation of low\u2010concentration oil spills by <jats:italic>Chlorella vulgaris<\/jats:italic> LH\u20101 immobilized in konjac glucomannan (KGM) aerogel were investigated. The effect of the KGM aerogel\u2010immobilized <jats:italic>C. vulgaris<\/jats:italic> on the bacterial community structure in seawater environments was analyzed through bacterial diversity sequencing. In seawater containing 0.01 and 1.00\u2009g\/L of crude oil, after 14\u2009days of remediation with the KGM aerogel\u2010immobilized <jats:italic>C. vulgaris<\/jats:italic>, crude oil removal rates of 98.73% and 95.13% were achieved, respectively. The FDA hydrolytic enzyme activity curve indicated that the microbial growth activity in the immobilized <jats:italic>C. vulgaris<\/jats:italic> group was significantly higher than that in other groups. After remediation, the top three dominant bacterial genera in the seawater were found to be <jats:italic>Vitellibacter<\/jats:italic>, <jats:italic>Roseitalea<\/jats:italic>, and <jats:italic>Methylophaga<\/jats:italic>. <jats:italic>Vitellibacter<\/jats:italic>, a genus known for its ability to degrade polycyclic aromatic hydrocarbons (PAHs) in marine environments, showed increased abundance in seawater treated with the KGM aerogel\u2010immobilized <jats:italic>C. vulgaris<\/jats:italic>, suggesting enhanced PAH degradation capability in the presence of the immobilized <jats:italic>C. vulgaris<\/jats:italic>. Functional prediction using PICRUSt indicated that the oil metabolism capability of bacteria was promoted by the KGM aerogel\u2010immobilized <jats:italic>C. vulgaris<\/jats:italic>.<\/jats:p><\/jats:sec><jats:sec><jats:title>Practitioner Points<\/jats:title><jats:p><jats:list list-type=\"bullet\">\n<jats:list-item><jats:p>High degradation efficiency across various oil concentrations is exhibited by KGM\u2010immobilized microalgae.<\/jats:p><\/jats:list-item>\n<jats:list-item><jats:p>KGM aerogels effectively confine <jats:styled-content style=\"fixed-case\"><jats:italic>C.vulgaris<\/jats:italic><\/jats:styled-content>, reducing loss in marine systems.<\/jats:p><\/jats:list-item>\n<jats:list-item><jats:p>The impact of KGM aerogel\u2010immobilized <jats:styled-content style=\"fixed-case\"><jats:italic>C. vulgaris<\/jats:italic><\/jats:styled-content> on bacterial community structure in marine environments was analyzed.<\/jats:p><\/jats:list-item>\n<jats:list-item><jats:p>Immobilized <jats:styled-content style=\"fixed-case\"><jats:italic>C. vulgaris<\/jats:italic><\/jats:styled-content> enhanced the growth of polycyclic aromatic hydrocarbon\u2010degrading bacteria, such as <jats:italic>Vitellibacter<\/jats:italic>, in seawater.<\/jats:p><\/jats:list-item>\n<\/jats:list><\/jats:p><\/jats:sec>","DOI":"10.1002\/wer.70009","type":"journal-article","created":{"date-parts":[[2025,1,24]],"date-time":"2025-01-24T08:33:53Z","timestamp":1737707633000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Effect of konjac glucomannan\u00a0aerogel\u2010immobilized <scp><i>Chlorella vulgaris<\/i><\/scp> LH\u20101 on oil\u2010contaminated seawater remediation and endogenous bacterial community diversity"],"prefix":"10.1002","volume":"97","author":[{"given":"Zhuorong","family":"Du","sequence":"first","affiliation":[{"name":"Zhejiang Key Laboratory of Petrochemical Environmental Pollution Control Zhejiang Ocean University  Zhoushan P.
