Biotechnology revival: in situ sludge minimization in wastewater

Frontiers in Microbiology, Год журнала: 2025, Номер 16

Опубликована: Май 2, 2025

In the face of escalating challenge sludge production and disposal in wastewater treatment plants (WWTPs), situ reduction biotechnology (ISRB) has recently emerged as a highly promising strategy. It not only potential to curtail generation at its origin but also ensures sustained efficiency process. Several key strategies have demonstrated exceptional harnessing microbial processes for degradation. They encompass enzymatic hydrolysis, inoculation, protozoan/metazoan predation, bacteriophage lysis, biofilm-based manipulation. Compared traditional methods (e.g., incineration landfilling), these biotechnologies offer significant advantages through lower costs, reduced energy consumption, minimal environmental impacts. The efficacy ISRB is substantially affected by various factors, where pH, shift, nutrient conditions play crucial roles. Despite notable progress made this field, challenges persist when it comes scaling up technologies more extensive widespread applications. This review comprehensively highlights fundamental mechanisms, application strategies, future prospects ISRB, including one first studies introduce bacteriophage-based approaches reduction, offering novel perspective on phage-mediated control. By doing so, aims in-depth insights into role sustainable solution management, paving way further research development area biotechnology.

With the increase in traffic due to urbanization, tire wear particles (TWPs) derived compounds persistently accumulate soil environment. This study addresses critical knowledge gaps regarding ecotoxicological effects of TWP-derived contaminants, N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) and its precursor, 6PPD-quinone (6PPD-Q), on soil-dwelling organisms. The findings demonstrated that 6PPD-Q accumulated at a higher concentration (6.77 ± 0.124 ng/g) earthworms (Eisenia fetida) compared 6PPD (5.41 0.002 ng/g), triggering more severe oxidative stress cellular homeostatic imbalance. Specifically, 100 ng/g significantly elevated reactive oxygen species (ROS) levels by 180.77% suppressed acetylcholinesterase (AchE) Ca2+-ATPase activities 17.14% 44.70%, respectively. Notably, uniquely disrupted nitrogen balance disturbed energy supply strongly inhibiting fatty acid degradation peroxisome proliferator-activated receptor (PPAR) signaling pathways. Additionally, profoundly altered abundance key microbes microbial network stability, affecting intestinal functions such as bile secretion, hormone synthesis, lipid digestion, thus exacerbating metabolic imbalance earthworms. deciphers molecular toxicity mechanisms contaminants earthworms, providing crucial insights for developing risk assessment frameworks mitigation strategies ecosystems.

Metabolic pathways from the gut metatranscriptome are associated with COPD and respiratory function in lung cancer patients

Frontiers in Cellular and Infection Microbiology, Год журнала: 2024, Номер 14

Опубликована: Ноя. 20, 2024

Changes in the human gut microbiome have been linked to various chronic diseases, including obstructive pulmonary disease (COPD). While substantial knowledge is available on genomic features of fecal communities, little known about microbiome's transcriptional activity. Here, we analyzed metatranscriptomic (MTR) abundance MetaCyc pathways, SuperPathways, and protein domain families (PFAM) represented by a cohort non-small cell lung cancer (NSCLC) patients with- or without COPD comorbidity.
