Environmental data analysis and modelling
A kinetic model was used to describe the anaerobic co-digestion of chicken manure (CM) and Thai rice noodle wastewater (TRNW) in continuous reactors. This research investigated the effects of mixing interval and hydraulic retention time (HRT) on methane production and other related kinetic...
Soil and groundwater contamination and remediation
Due to its cost-effectiveness and absence of secondary pollution, the biological approach for eradicating chloride pollution has attracted widespread interest. However, numerous obstacles, including the limited presence of degrading microbes and a substantial impact from environmental variables...
Sustainable Energy
In this study, milk waste water will be extracted, transformed into Lipolytic microorganism’s biodiesel (LMD) using transesterification, and tested for appropriateness as an alternative, sustainable, renewable source for IC engines. The properties of the created blends of biodiesel were investigated...
Environmental management and policy
The microbial consortia incorporated in bio concrete should have traits such as high alkali resistance and the ability to form endospores to overcome the mechanical and chemical stresses produced during concrete preparation. The primary intent of our work is to segregate and identify the calcium...
Water and wastewater treatment and reuse
Waste generated as a result of the leather processing industry can be in the form of solid, liquid and gas waste. Waste generated from the textile industry made from clothing H2S and TSS which if not treated properly, will be very dangerous for health and the environment. One of the efforts to...
Water and wastewater treatment and reuse
The pollution and toxicological effects of microplastics in soil have gradually attracted widespread attention, but studies on the ecological effects of microplastics on soil microorganisms and their mechanisms are still very scarce. To explore the physiological response of ectomycorrhizal fungi...
Water and wastewater treatment and reuse
Water treatment ecosystem provides important habitats for various bacterial communities, but the response mechanism of this ecosystem under ultraviolet rays is not yet clear. For this reason, 16S rRNA gene sequencing is used to study the bacterial community structure and metabolic pathways under...
Water and wastewater treatment and reuse
The unique high-altitude environmental factors in the Linzhi region of Tibet have not been fully investigated in terms of their impact on the microbial mechanisms of water ecology, for which we explored the response of activated sludge microorganisms to different hydraulic retention times (HRT)...
Water and wastewater treatment and reuse
ABSTRACT Plastic pollution is increasing and plastic waste usually ends in environment. Microplastics (MP) as insoluble and anthropogenic micropollutant is ubiquitous and its concentration is expected to increase in the environment. One of important sources are wastewater treatment plants, where...

Contamination in water bodies with antibiotics and resistance genes is becoming an increasing threat to global health. Overuse of antibiotics has become a serious ecological problem worldwide. There is growing concern that antibiotics are losing their effectiveness due to increased antibiotic...
Solid Waste Management
Many eutrophic lakes contain rapidly growing hydrophytes. Overgrown biomass is usually me-chanically harvested and thrown away, leading to resource waste and secondary environmental pollution. Microbial degradation is an economically and environmentally friendly approach for managing hydrophytic...
Water and wastewater treatment and reuse
The long start-up time and high demand of anaerobic ammonium oxidation (anammox) limit the practical applications of the anammox process. In this study, granular sludge supported on activated carbon (AC) was used as seed sludge. The start-up time of the reactor was substantially shortened, and the...
This review deals with the importance of molybdenum (Mo) in nitrogen fixation in forests as well as the distribution of Mo in the various components of a forest ecosystems and its cycling. With regard to nitrogen (N) fixation in tropical forests, the limiting factor is the availability of phosphorus...
