We found that increasing biofilm levels, by manipulating the levels of the second messenger, Cyclic-di-GMP, led to increased levels of polyester degradation in cells expressing novel and well characterised polyester-degrading enzymes. This indicates that modulating biofilm formation is a viable ...
We’ve discovered microorganisms that naturally feed off the chemicals and compounds inplasticwaste by digesting and breaking them down into harmless organic matter. And now we're enhancing these microorganisms and enzymes associated with the degradation. Distributing these enhanced microorganisms and enzyme...
Decomposition mechanisms of plastic include 1) photo-oxidation, physical weathering, plowing and harrowing as well as 2) degradation by microorganisms (Sander, 2019). The (bio)degradation-induced generation of secondary MPs and NPs in agricultural soils is a major issue of concern as at the micro...
The biodegradability of organic substances is the degree of the changes in physical and chemical characteristics and molecular structure of organic substances under degradation by microorganisms. Fig. 1 illustrates the biodegradation processes of organic substances under aerobic conditions (Jiang et al., 20...
The degradation of synthetic polymers by marine microorganisms is not as well understood as the degradation of plastics in soil and compost. Here, we use metagenomics, metatranscriptomics and metaproteomics to study the biodegradation of an aromatic-aliphatic copolyester blend by a marine microbial ...
Each year, approximately 9.5 million metric tons of plastic waste enter the ocean with the potential to adversely impact all trophic levels. Until now, our understanding of the impact of plastic pollution on marine microorganisms has been largely restric
Before we explore the nuances of plastic degradation, let’s take a look at the overall idea of decomposition. After all, plastic isn’t the only type of waste that we need to find a place for on this planet. The problem of waste removal and disposal is everywhere, and when improperly ...
The increasing incorporation of these materials and its impact on the environment are due largely to having resistance to corrosion, weathering, and degradation by microorganisms. Why Zurich : Zurich is the largest city in Switzerland and the capital of the canton of Zürich. It is located in ...
degradation rate up to 15 mol% PHHx, which then sharply declines as PHHx fraction continues to increase up to 25 mol% (Doi et al., 1995). Commercial and scientific fermentative production of PHAs is largely accomplished by fermentation of either native or recombinant microorganisms. Native ...
Biodegradation of polymers (including PLA) usually takes place in two main steps: primary degradation, in which fragmentation of the polymer chain occurs due to hydrolysis or another oxidative reaction, and ultimate biodegradation, in which the microorganisms assimilate the lowMwchains formed (Fig. 2...
