Antimicrobial resistance in soil bacteria without the use of antibiotics: Predatory interactions drive development

Overuse of antibiotics is currently the primary reason for the rise of antimicrobial resistance (AMR). Researchers at the Indian Institute of Science (IISc) and Kiel University, however, have shown that AMR can surprisingly be found in soil bacterial communities due to microbial interactions too, driven by a species of predatory bacteria.

Bacteria on marine particles play key role in ocean nitrogen cycle

It has puzzled scientists for years whether and how bacteria, that live from dissolved organic matter in marine waters, can carry out N2 fixation. It was assumed that the high levels of oxygen combined with the low amount of dissolved organic matter in the marine water column would prevent the anaerobic and energy consuming N2 fixation.
