Biodegradation of plastics through the use enzymes provides an attractive, environmentally friendly solution to dispose and recycle plastic wastes. Although many natural engineered plastic-degrading have been developed, their practical applications are hindered by biodegradation in open environments. We reasoned that most popularly used plastics, such as polyethylene terephthalate (PET), achira...

Biosurfactants, a wide group of compounds produced by different microorganisms, generally have less toxicity and are more biodegradable than synthetic surfactants. Biosurfactant-producing bacteria can be found in contaminated environments, such as soils receiving pesticide applications constantly, or pesticides treatment systems where microorganisms adapted to biodegrading pesticides. Five pest...

To stimulate plant development in phytoremediation or the cultivation of non-food crops potentially contaminated soils, a biotechnologically created product could be applied. The aim this study was to explore possibility creation biofertiliser, based on activated sludge combined with bacterial strain detoxifying and growth promoting properties. presented is focused effect phenol following conce...

Heavy metal contamination is accidentally becoming prevalent in Antarctica, one of the world’s most pristine regions. Anthropogenic as well natural causes can result heavy contamination. Each has a different toxic effect on various microorganisms and species, which interfere with other pollutant bioremediation processes. This study focused co-contaminant metals waste canola oil (WCO) biodegrada...

With the present climate change and increasing world population, there is an urgent need to discover creative, efficient, cost-effective natural products for benefit of humanity. Biosurfactants are produced by various microorganisms that have several distinct properties compared other synthetic surfactants, including mild production conditions, multifunctionality, higher biodegradability, lower...

Nodularin (NOD) is greatly produced by Nodularia spumigena and released into the environment when toxic cyanobacterial blooms happened in natural water body, which is seriously harmful to human and animals. The promising bacterial strain of Sphingopyxis sp. USTB-05 was found to have an ability in biodegrading NOD. Initially, 11.6 mg/L of NOD could be completely eliminated within 72 h by whole c...

A total of thirty endophytic fungi were isolated from leaves and twigs of Eucalyptus globulus and Eucalyptus citriodora. Among thirty endophytic fungal isolates, four (P3MT1, P3MT2, OP4MT2 and P7ML2) are consistently producing compounds which are inhibiting Pseudomonas aeroginosa, Mycobacterium smegmatis and Candida albicans even after 10 generations tested under dual culture, well diffusion an...

Endocellulases are one kind of the important biodegrading cellulose enzymes. Experimental results show that a rotated and distorted preactivated structure exists before the substrate entering the transition state. The molecular dynamic simulation of endocellulase Cel6A models revealed a correlation between the rotation and distortion of pyranoside ring in -1 glycosyl unit of the substrate. The ...
