Random effects make it difficult to optimise antibiotic therapy

Research team from the Kiel Evolution Center investigates the role of a reduction in bacterial population size and resulting random effects in the evolution of antibiotic resistance

28-Jul-2021

Antibiotic-resistant pathogens have become one of the greatest threats to public health. In just a few years, previously harmless bacterial infections may no longer be treatable and may once again become a leading non-natural cause of death, as they were before the antibiotic era began until the ...

Microbes in cow stomachs can break down plastic

Eco-friendly way to reduce litter?

07-Jul-2021

Plastic is notoriously hard to break down, but researchers in Austria have found that bacteria from a cow's rumen - one of the four compartments of its stomach - can digest certain types of the ubiquitous material, representing a sustainable way to reduce plastic litter. The scientists suspected ...

Tailor-made enzymes for chemical toxins?

Hiding in the midst of trash are valuable bacteria that can degrade environmental toxins

21-Jun-2021

Bacteria from an Indian landfill could help eliminate contaminated chemicals. The focus is on pesticides or brominated flame retardants, which accumulate in nature and in food chains. Researchers at Empa and Eawag used these bacteria to generate enzymes that can break down these dangerous ...

Bacteria serves tasty solution to global plastic crisis

Scientists have devised a novel way of tackling the mounting issue of plastic pollution -- by using bacteria to transform plastic waste into vanilla flavoring

14-Jun-2021

Researchers have discovered that the common bacteria E. coli can be deployed as a sustainable way to convert post-consumer plastic into vanillin, a new study reveals. Vanillin is the primary component of extracted vanilla beans and is responsible for the characteristic taste and smell of ...

Efficiently "switching on" bacteria to produce high-value chemicals

Researchers have found a cheap way to switch bacteria into chemical production mode

10-Jun-2021

High-value chemicals used in biofuels and pharmaceuticals can be made from bacteria by switching their chemistry to produce novel products. Researchers from the University of Warwick have found a way to drastically cut the cost of turning on these switches.We use chemicals for almost everything, ...

Recruiting bacteria to build catalysts atom by atom

An enigmatic bacterium proves a useful ally for the synthesis of single-atom catalysts to split hydrogen from water

02-Jun-2021

Exploiting the unusual metal-reducing ability of the iron-breathing bacterium Geobacter sulfurreducens, KAUST researchers have demonstrated a cheap and reliable way to synthesize highly active single-atom catalysts. The innovation, which could dramatically improve the efficiency and cost of ...

White biotechnology enables carbon recycling

LanzaTech and BASF achieve first milestone in utilizing industrial off-gases for chemical production

14-May-2021

Transforming the carbon contained in industrial off-gases into valuable chemicals is the aim of a partnership between LanzaTech and BASF. Now the partners have achieved a key first success: With the help of special bacteria, they have been able to produce n-octanol at laboratory scale from carbon ...

Harnessing the power of microbial communities for plastic degradation

Researchers propose new approach in the search for biological plastic degradation

23-Apr-2021

Bacteria are extremely adaptable. The more plastic enters the environment, the more likely they are to find ways to extract energy from plastic and degrade them in the process. Us humans could take advantage of this. The trick is to find the respective bacteria and combine them in novel ways. In ...

Aviation safety: Rapid test for harmful microbes in kerosene developed

Faster and more robust than a PCR test

12-Apr-2021

Fuels such as kerosene or diesel can be contaminated by fungi or bacteria. The microorganisms settle in the liquid itself, on the inner walls of tanks and pipes or in fuel filters and feed on carbon atoms. Since the fungi and bacteria multiply well in this environment, they can form a streaky ...

Cellular powerplant recycles waste gases

The idea is to use the power of bacteria to turn toxic waste gases into valuable compounds such as acetate or ethanol

19-Nov-2020

Carbon monoxide is a very poisonous gas. Humans die within minutes when they inhale it. However, some microorganisms tolerate carbon monoxide and even use it to breathe and replicate. Knowledge about how these bacteria survive opens a window into the primeval times of the earth and the origin of ...
