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.
Mapping the evolutionary timeline and population distribution of E. coli’s protective outer capsule
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.
Beggiatoa's lipoxygenase: does a close relative of Thiomargarita magnifica carry a biochemical secret? | Research Communities by Springer Nature
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?
Getting a grip: The molecular mechanisms of Bdellovibrio attachment | Research Communities by Springer Nature
For a predatory bacterium that consumes other bacteria, attaching to its prey is a crucial step in the B. bacteriovorus lifestyle. Until now there has been no known means for this attachment.
Buruli ulcer transmission and the philosophy of science | Research Communities by Springer Nature
Buruli ulcer is a 'flesh-eating' bacterial infection of skin and soft tissue. Since the discovery in the 1940s of the causative agent Mycobacterium ulcerans, scientists have puzzled over how the infection is spread from the environment to humans.
Researchers discover Paleocene origin of symbiotic relationships in leaf beetles
Brightly colored beetles that feed on a wide range of plants possess robust metabolic capabilities, thanks to bacteria residing in specialized organs in their digestive tract. The bacterium Stammera provides essential enzymes enabling Cassidinae beetles to digest plant cell wall components efficiently.
Phage Therapy as a Promising Approach for Tuberculosis Treatment: A Comprehensive Study | Research Communities by Springer Nature
Mycobacterium tuberculosis (Mtb), the causative agent of Tuberculosis (TB), is a global health concern with significant morbidity and mortality rates. Traditional antibiotics are increasingly ineffective against multidrug-resistant TB. In this context, alternative therapies are urgently needed.
Surprising bacterium from Canadian lake shines new light on ancient photosynthesis
Sometimes an experiment doesn't go as planned. That's science. But a "failed" experiment or unexpected results can be the avenue to a discovery you could never anticipate. University of Waterloo Ph.D. student Jackson Tsuji had a poorly growing bacterial sample he wasn't ready to give up on, which ultimately led to a once-in-a-lifetime finding that could change how scientists view photosynthesis and its origins.
