Lichen on tree trunk

Lichen, a consortium of cyanobacteria and fungus in a symbiotic relationship, is commonly found on damp concrete surfaces where the moisture made an otherwise inhabitable niche into a habitable one. Moisture together with photosynthetic cyanobacteria enable the churning out of complex organic mo... Read More

'Farming' bacteria to boost growth in the oceans

Chemosynthetic symbionts are bacteria living inside or on the surface of animals, supplying their host with food that would otherwise be unavailable. It has long been known that these bacteria fix carbon and convert it into organic forms. Microbiologist Jillian Petersen and colleagues from the U... Read More

Microbe Mafia

Meet the Microbe Mafia: K. rhizophila, E. coli, and C. xerosis. They might seem like friendly bacteria but are always looking for opportunities to cause disease. Well ..... K. rhiz is really not that bad but peer pressure works in bacterial populations as well. When armed with C. violaceum th... Read More

Microscopic technique to observe antibiotics live in action

A new microscopic technique is enabling scientists to observe the antibiotic daptomycine live in action. This marks an exciting first, because even though doctors have been prescribing this antibiotic for over a decade, its precise mechanisms have remained unclear.

First, the scientists tagg... Read More

Microbe hunters discover long-sought-after iron-munching microbe

A microbe that ‘eats’ both methane and iron: microbiologists have long suspected its existence, but were not able to find it - until now. Researchers at Radboud University and the Max Planck Institute for Marine Microbiology in Bremen discovered a microorganism that couples the reduction of iron... Read More
