Harnessing the potential of specific antibiotic-degrading microalgal strains to optimize microalgal-bacterial granular sludge (MBGS) technology for sustainable antibiotic wastewater treatment and resistance genes (ARGs) mitigation is currently limited. This article examined performance bacterial (BGS) MBGS (of Haematococcus pluvialis, an microalga) systems in terms stability, nutrient removal, fate ARGs mobile genetic elements (MGEs) under multiclass loads. The exhibited excellent none 50 μg/L mixed antibiotics a decrease at higher concentration. showed superior potential, 53.9 mg/L/day chemical oxygen demand (COD) 5.2–8.2% improved notably refractory antibiotics, system removal capacity was predicted. Metagenomic analysis revealed lower levels MGEs effluent biomass compared BGS bioreactor. Particle association niche projection pursuit regression models indicated that microalgae may limit gene transfers among effluent, impeding ARG dissemination. Moreover, discrepancy found biomarkers due effect on microcommunity. Altogether, these findings deepened our understanding microalgae's value remediation propagation control.

Research progress and prospect of low-carbon biological technology for nitrate removal in wastewater treatment

Frontiers of Environmental Science & Engineering, Год журнала: 2024, Номер 18(7)

Опубликована: Март 25, 2024

Abstract Wastewater treatment plants are the major energy consumers and significant sources of greenhouse gas emissions, among which biological nitrogen removal wastewater is an important contributor to carbon emissions. However, traditional heterotrophic denitrification still has problems excessive residual sludge requirement external sources. Consequently, development innovative low-carbon nitrate technologies necessary. This review outlines key roles sulfur autotrophic hydrogen in treatment. The discovered nitrate/nitrite dependent anaerobic methane oxidation enables sustainable emission reduction by utilizing available situ . Photosynthetic microorganisms exhibited a promising potential achieve carbon-negative removal. Specifically, algal-bacterial symbiosis system photogranules offer effective prospective options for Then, emerging technology photoelectrotrophic underlying photoelectron transfer mechanisms discussed. Finally, we summarize prospect these technologies, highlighting that solar-driven area future guiding significance design systems.

Abstract Ocean oil spills can severely impact ecosystems and disrupt marine biodiversity habitats. Microbial remediation is an effective method for removing thin slick contamination. In this study, the adsorption degradation of low‐concentration by Chlorella vulgaris LH‐1 immobilized in konjac glucomannan (KGM) aerogel were investigated. The effect KGM aerogel‐immobilized C. on bacterial community structure seawater environments was analyzed through diversity sequencing. containing 0.01 1.00 g/L crude oil, after 14 days with , removal rates 98.73% 95.13% achieved, respectively. FDA hydrolytic enzyme activity curve indicated that microbial growth group significantly higher than other groups. After remediation, top three dominant genera found to be Vitellibacter Roseitalea Methylophaga . a genus known its ability degrade polycyclic aromatic hydrocarbons (PAHs) environments, showed increased abundance treated suggesting enhanced PAH capability presence Functional prediction using PICRUSt metabolism bacteria promoted Practitioner Points High efficiency across various concentrations exhibited KGM‐immobilized microalgae. aerogels effectively confine C.vulgaris reducing loss systems. analyzed.
