Trehalose promotes Rhodococcus sp. strain YYL colonization in activated sludge under tetrahydrofuran (THF) stress

Frontiers in Microbiology, 2015
Few studies have focused on the role of compatible solutes in changing the microbial community structure in bioaugmentation systems. In this study, we investigated the influence of trehalose as a biostimulant on the microbial community in THF-treated ...

Bacterial Volatile Organic Compounds Mediate a Cooperative Relationship Between Bacteria and Plants Under Heavy Metal Stress

Microbial Biotechnology, Volume 19, Issue 8, August 2026.
In this brief report, we propose a scenario in which bacterial volatile organic compound (BVOC)‐mediated communication with plants can be interpreted as a form of plant–microbe cooperation under heavy metal stress. Different VOCs are emitted depending on bacterial stress states, and VOCs from heavy metal‐stressed bacteria modulate plant defense ...

Comparative bioremediation of heavy metals and petroleum hydrocarbons co-contaminated soil by natural attenuation, phytoremediation, bioaugmentation and bioaugmentation-assisted phytoremediation

, 2015
Biological remediation technologies are an environmentally friendly approach for the treatment of polluted soils. This study evaluated through a pot experiment four bioremediation strategies: a) natural attenuation, b) phytoremediation with alfalfa ...

Augmentation of Granular Anaerobic Sludge with Algalytic Bacteria Enhances Methane Production from Microalgal Biomass

Fermentation, 2019
The efficiency of anaerobic digestion relies upon activity of the inoculum converting organic substrate into biogas. Often, metabolic capacity of the inoculum needs to be augmented with new capabilities to accommodate changes in the substrate feed ...

Effect of bioaugmentation on digestate metal concentrations in anaerobic digestion of sewage sludge.

PLoS ONE, 2020
This study examined the influence of bioaugmentation on metal concentrations (aluminum, cadmium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel and zinc) in anaerobically digested sewage sludge.

Substrate‐driven enrichment and eDNA metabarcoding reveal indigenous microbiomes in mangrove sediments with potential for ammonia and nitrite transformation

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract Effective management of ammonia and nitrite remains a major challenge in intensive shrimp aquaculture, where excessive nitrogen loading compromises water quality and animal health. Indigenous microbial communities inhabiting mangrove sediments are widely considered potential sources of ammonia‐ and nitrite‐transforming microorganisms; however,

Bioaugmentation Versus pH Adjustment in High-Load Food Waste Anaerobic Digestion: Divergent Microbial Responses and Methanogenesis Regulation

Fermentation
High organic loading is known to destabilize anaerobic digestion (AD). This study compared bioaugmentation and pH adjustment under increasing organic loading rate (OLR: 2.0, 4.0 and 6.0 gVS L−1 d−1), focusing on the responses of microbial structure ...

Waste to Hydrogen: Transforming Food Waste Into Biohythane (Bio‐H2 + Bio‐CH4) in a Two‐Stage Reactor With the Aid of a Metal‐Ion Catalyst

Energy Science &Engineering, Volume 14, Issue 7, Page 3388-3421, July 2026.
This study demonstrates a two‐stage catalytic bioreactor system that converts real food waste into high‐purity biohydrogen and biohythane. In Stage‐1, an enriched Clostridium thermocellum culture combined with Ni2+─Fe2+ bimetallic catalysis enhances hydrolysis efficiency and hydrogenase activity, resulting in a 77% increase in H2 yield and 75.8% purity
