1. RsbX and stress response in Listeria monocytogenes
Abstract : Listeria monocytogenes is a ubiquitous foodborne Gram-positive bacterium. Despite being mainly a soil bacterium, it can reach the food processing environment and contaminate food destined for human consumption, causing outbreaks. READ MORE

2. Ammonia-Oxidising Bacteria in Soil : Studies of diversity and abundance using 16S rRNA gene analysis
Abstract : Nitrification is the process whereby ammonia is oxidised to nitrate. The first step of this process is carried out by the chemoautotrophic, ammonia-oxidising bacteria (AOB), which convert ammonia to nitrite. READ MORE

3. Drivers of soil fungal communities in boreal forests : feedbacks on soil fertility and decomposition
Abstract : Boreal forests harbour diverse fungal communities with decisive roles in decomposition and plant nutrition. Difficulties in studying soil fungi have limited knowledge about how fungal communities are shaped. READ MORE

4. Microorganisms in the atmosphere
Abstract : Bacteria are present everywhere around us; in water, soil, food, on our skin, and in the air we breathe, mainly as parts of aerosols (i.e. minute air-suspended particles). Aerosols are mainly composed of sea salt, dust, sulphates and soot but some also contain bacteria, virus, pollen, plant debris and organic matter (i. READ MORE

5. Antibiotic Resistance in Wastewater : Methicillin-resistant Staphylococcus aureus (MRSA)and antibiotic resistance genes
Abstract : A large part of the antibiotics consumed ends up in wastewater, and in the wastewater the antibiotics may exert selective pressure for or maintain resistance among microorganisms. Antibiotic resistant bacteria and genes encoding antibiotic resistance are commonly detected in wastewater, often at higher rates and concentrations compared to surface water. READ MORE
