6. Investigation of a Biofilm Reactor Model with Suspended Biomass
Abstract : Biofilms are compact, sessile microbial communities that attach to surfaces in aqueous environments. In wastewater treatment, they are especially important for removal of phosphorus and nitrogen, which, if released into a receiving water body, can cause severe eutrophication. READ MORE

7. Mycorrhizal guild functions and conservational values in boreal forests
Abstract : The immense diversity and biomass of ericoid-, ectomycorrhizal, and saprotrophic fungal guilds in boreal forest soils make them vital components of conservation and ecosystem processes, and in particular, many ectomycorrhizal fungi are considered species of conservation concern. However, amalgamated information on the functions and relationships of soil fungi to perceived forest conservation values, and how inter and intra-guild interactions affect the accretion and decomposition of soil organic matter is lacking.

8. Effects of heavy metal contamination on carbon and nitrogen cycling : An ecological approach to assess risks to soil functions
Abstract : Soil contamination with heavy metals may disrupt soil microorganisms with important roles in carbon (C) and nitrogen (N) cycling. However, there is a lack of understanding on how microorganisms are affected in soil, which may lead to a mismatch when assessing risks of contaminants to field soils. READ MORE

9. Microbial polymers produced from residual biomass: exploring the potential of different microbes
Abstract : Microorganisms are important sources of diverse intracellular and extracellular biopolymers havingdifferent functions such as serving as carbon and energy reserves, or as protective layers around the cells in theform of capsules and/or biofilms. They have also found use in foods, medicine and other industrial applications. READ MORE

10. Soil salinity as a driver of microbial community structure and functioning
Abstract : Soil salinization is a pressing agricultural problem in many areas of the world, particularly in areas heavily reliant on irrigation agriculture. While the negative effects of salinity on crop plants have been widely studied, its effects on soil microorganisms have received less attention, and the impact of soil salinity on both microbial community structure and functioning is not well understood.
