1. Scientists Find Bacteria That Eats Plastic In a breakthrough study, scientists have identified a strain of bacteria that is capable of breaking down the plastic found in food packaging and other products. The bacteria, Ideonella sakaiensis 201-F6, was discovered living on plastic debris at a waste disposal site in Japan. The research team, which was led by Professor Shosuke Yoshida from the Kyoto Institute of Technology, found that I. sakaiensis 201-F6 had the ability to break down polyethylene terephthalate (PET) plastic. The bacteria use two enzymes to convert the PET into a more easily metabolized form, which then allows them to feed on it as a source of energy. This is the first time that a microorganism has been observed to have the ability to degrade PET plastic. The findings could have significant implications for helping to reduce the amount of plastic waste in the environment.
Modern eukaryotic cells contain numerous organelles, which once used to be independent bacteria. In order to understand how these bacteria were integrated into the cells in the course of evolution and how they are controlled, a research team from the Institute of Microbial Cell Biology at Heinrich Heine University Düsseldorf (HHU) has examined the single-celled flagellate Angomonas deanei, which contains a bacterium that was taken up relatively recently.
A new study discussed the findings of Chai et al., which revealed that triple specificity protein phosphatase (ptpB) secreted by Mycobacterium tuberculosis inhibits pyroptosis and the release of cytokines by macrophages, allowing M. tuberculosis to invade the immune system.
Seeking to better understand more about the origins and movement of bubonic plague, in ancient and contemporary times, researchers have completed a painstaking granular examination of hundreds of modern and ancient genome sequences, creating the largest analysis of its kind.
Announcing a new article publication for Zoonoses journal. As infections caused by nontuberculous mycobacteria (NTM) are rapidly increasing globally, a need exists for developing novel antibiotics and discovering the mechanism of resistance
In a new study, published today (15 June) in Nature Communications, a multi-centre team led by the Wellcome Sanger Institute, the University of Oslo, Imperial College London and UCL, has mapped for the first time the evolutionary timeline and population distribution of Escherichia coli’s protective outer capsule, which is responsible for the bacterium’s virulence.
Discovery of Thiomargarita magnifica — the biggest-ever bacterium — urged us to revisit our recent bioinformatic finding of lipoxygenase enzyme in Beggiatoa, the closest relatives of Thiomargarita. Is this cell-to-cell signalling marker somehow related to Beggiatoa's and Thiomargarita's large size?
