Biotechnology Methods for API Removal From Pharmaceutical Wastewater

Advances in environmental engineering and green technologies book series, Journal Year: 2025, Volume and Issue: unknown, P. 299 - 336

Published: Jan. 16, 2025

In recent decades, the use of pharmaceutical products has been increased tremendously with over thirty million tons pharmaceuticals are consumed worldwide. Pharmacological drugs have a crucial role in preserving health and welfare both humans animals. Many used not completely metabolized human animal body leading to gets accumulated rivers, lakes, drinking water worldwide as persistent organic chemicals causing severe damage aquatic ecosystems. This chapter analyses several biotechnology methods employed remove APIs from wastewater, specifically emphasizing biological treatments that harness capabilities microorganisms enzymes. The present paper provides thorough analysis microbial degradation, bioaugmentation, application bioreactors. Furthermore, it highlights efficacy, challenges, potential for integration into existing treatment systems (Figure 1).

Mechanisms Driving Seasonal Succession and Community Assembly in Sediment Microbial Communities Across the Dali River Basin, the Loess Plateau, China

Microorganisms, Journal Year: 2025, Volume and Issue: 13(2), P. 319 - 319

Published: Feb. 1, 2025

Microorganisms are instrumental in river ecosystems and participate biogeochemical cycles. It is thought that dynamic hydrological processes rivers influence microbial community assembly, but the seasonal succession assembly of sediments on Loess Plateau remain unclear. This study used high-throughput sequencing technology (16S ITS) neutral model to analyze associated with communities Dali River, a tributary Yellow River Plateau. The results showed sediment bacterial fungal diversity indexes non-flood season were 1.03–3.15 times greater than those flood season. There obvious variations between seasons microorganisms. similarities among all, abundant, rare decreased as geographical distance increased. Proteobacteria (52.5–99.6%) Ascomycota (22.0–34.2%) primary phyla communities. Sediment ammonia nitrogen, water temperature, organic carbon significantly affected (p < 0.05) structure microorganism ecological networks for had complex topological parameters. was driven by deterministic processes, while dominated stochastic processes. These expanded understanding about characteristics provided insights into factors driving networks.

Microbial Diversity in Mining–Affected Forest Ecosystems: Exploring the Roles of Seasonality and Environmental Factors in Qinyuan County, Shanxi Province

Diversity, Journal Year: 2025, Volume and Issue: 17(3), P. 199 - 199

Published: March 11, 2025

China has significant mineral resources, but prolonged extraction caused considerable environmental degradation. Interactions among rhizosphere, phyllosphere, and soil microorganisms, along with host plants, are essential for supporting plant growth increasing stress tolerance. This study employed high–throughput sequencing to assess microbial diversity community structure related four common tree species in the mountainous areas of Shanxi Province, samples collected from three regions over two seasons locations. The dominant fungal bacterial phyla identified were Ascomycota, Basidiomycota, Mortierellomycota, Pseudomonadota, Actinobacteriota, Gemmatimonadota, Acidobacteria, Myxococcota, Firmicutes. Alpha–diversity analysis revealed that Taiyue Mountain exhibited highest plots, while Liushenyu displayed diversity. was greater spring than summer across seasons. Significant differences observed different species, Betula platyphylla showing lowest In comparison phyllosphere rhizosphere microorganisms higher diversity, richness, evenness. Beta–diversity indicated composition between samples, as well leaves, roots, soil. assessment physicochemical properties redundancy demonstrated moisture content organic matter key factors influencing communities. These findings provide valuable insights into structural changes communities mining restoration damaged ecosystems.

Comparative analysis of crab growth performance, enzyme activity, and microbiota between rice-crab coculture and pond farming systems

Frontiers in Veterinary Science, Journal Year: 2025, Volume and Issue: 12

Published: March 19, 2025

To support the sustainable development of rice and aquaculture industries, various rice-animal coculture systems have been developed. One such system, rice-crab system (RCC), has practiced for decades in northern China. However, studies on crab physiological status RCC remain limited. Microorganisms play a crucial role by influencing animal nutrition, health, nutrient cycling, water quality, environmental impact. Research gut microbiota is scarce. This study compared growth performance, immune digestive enzyme activities crabs between traditional pond farming (PF). In addition, guts, water, sediment from both was investigated using 16S rRNA gene sequencing. Crabs exhibited superior performance higher enzymatic activities, including acid phosphatase (ACP), alkaline (AKP), lipase (LPS), trypsin (TRY). Significant differences were observed composition across gut, samples, respectively. had lower abundance Bacteroidota Firmicutes their microbiota. The environment enriched with beneficial bacteria as Rhizobiales, Methylococcales, KD4-96, C39, Xanthomonadales, Nitrosomonadaceae. Microbial function predictions confirmed enhanced methanotrophy nitrogen fixation RCC. enhances rate capability crabs. consume more animal-based which results distinct levels LPS TRY to those PF. Additionally, supports environmentally that contribute greenhouse gas reduction, carbon fixation, organic matter decomposition, ammonia oxidation, benefiting ecosystem. These findings enhance our understanding physiology microbial communities PF systems.
