Rotating biological contactors for wastewater treatment - A review [PDF]

, 2015
Rotating biological contactors (RBCs) for wastewater treatment began in the 1970s. Removal of organic matter has been targeted within organic loading rates of up to 120 g m−2 d−1 with an optimum at around 15 g m−2 d−1 for combined BOD and ammonia removal.

Electrifying enzymatic bioproduction

, 2020
A microbial battery couples waste degradation to a specific enzymatic production process. This is enabled by the uncoupling of the waste oxidation process from the enzymatic bioproduction via redox cathodes. The approach can be attractive for small-scale,

Review of key causes and sources for N2O emmisions and NO3-leaching from organic arable crop rotations [PDF]

, 2018
. The emissions of nitrous oxide (N2O) and leaching of nitrate (NO3) have considerable negative impacts on climate and the environment. Although these environmental burdens are on average less per unit area in organic than in non-organic production, they

Land use driven change in soil pH affects microbial carbon cycling processes

Nature Communications, 2018
Land use intensification could modify microbial activity and thus ecosystem function. Here, Malik et al. sample microbes and carbon-related functions across a land use gradient, demonstrating that microbial biomass and carbon use efficiency are reduced ...

Effect of pine bark and compost on the biological denitrification process of non-hazardous landfill leachate: Focus on the microbiology [PDF]

, 2010
In an attempt to optimize the cost-efficiency of landfill leachate treatment by biological denitrification process, our study focused on finding low-cost alternatives to traditional expensive chemicals such as composted garden refuse and pine bark, which

The pattern of soil microbe metabolic limitation and carbon use efficiency was altered by light grazing in typical steppe

Global Ecology and Conservation
The influence of grazing on the limiting of soil microbial metabolism is crucial for optimizing grazing management aimed at enhancing the soil's capacity for carbon sequestration in grasslands.

Global climate change and tree nutrition: effects of elevated CO2 and temperature [PDF]

, 2010
Although tree nutrition has not been the primary focus of large climate change experiments on trees, we are beginning to understand its links to elevated atmospheric CO2 and temperature changes. This review focuses on the major nutrients, namely N and P,

A model of nitrous oxide evolution from soil driven by rainfall events: 1. Model structure and sensitivity [PDF]

, 1992
This paper describes a rain-event driven, process-oriented simulation model, DNDC, for the evolution of nitrous oxide (N2O), carbon dioxide (CO2), and dinitrogen (N2) from agricultural soils.
