A decontamination composition, containing chloroperoxidase. The decontamination composition can rapidly degrade chemical warfare agents, namely mustard gas (HD), Lewisite (L) and VX, and the decontamination products of mustard gas and Lewisite are non-toxic, thereby effectively preventing the harm of the chemical warfare agents to the environment and organism, and reducing the degree of harm of the products to soil, vegetation and organism compared with conventional decontaminant agents.

Provided is a method for activating an oxygenase-containing composition, characterized by dissolving or dispersing a composition containing oxygenase in an aqueous medium containing oxygen in an amount that exceeds the saturated dissolved oxygen concentration in an atmospheric environment at normal temperature and normal pressure.

The disclosure relates to methods for degrading and/or removing pollutants comprising a phenol, aniline, a hydrocarbon, or a combination thereof, in a waste material. Methods include providing a viable corn plant expressing a fungus-derived recombinant manganese peroxidase in seeds of the corn plant, growing the corn plant, harvesting the seeds, and contacting one or more composition(s) comprising (1) at least a portion of the seeds, and (2) a peroxide or a peroxide source with the waste material comprising the pollutant to remove or degrade the pollutant.

A method for degrading naphthenic acid compounds present in naphthenic acid compounds-containing material into at least one compound of lower toxicity, said method comprising: -providing said naphthenic acid compounds-containing material; -exposing said naphthenic acid compounds-containing material to a modified Caro's acid composition for a period of time sufficient to degrade substantially all of the naphthenic acid compounds present in the naphthenic acid compound-containing material; -optionally, testing the treated material and assess a level of naphthenic acid compounds; and -optionally, releasing the treated material into a waterway.

Germanium-doped titania semiconductors, which are capable of photocatalyzed electron transfer are coated with electronic deficient fluorinated phthalocyanines capable of energy transfer. The combination of these pathways results in a broad spectrum photocatalyst useful for deactivating harmful chemical and biological agents.

The present invention is directed to an aqueous nanofluid composition and the method of use thereof for displacing or removing chemical warfare agents (CWAs) from capillary spaces, the nanofluid composition comprising water, colloidal silica, and at least one surfactant, such that the nanofluid composition is adjacent to the capillary features to absorb the CWAs from the capillary features. Upon displacement or removal, the CWAs are ready for disposal.

The present disclosure discloses an application of Loigolactobacillus coryniformis subsp. coryniformis in the efficient degradation of aflatoxin. The method is as follows: Loigolactobacillus coryniformis subsp. coryniformis 523L5 is inoculated into LB broth containing Aflatoxin B1, and Aflatoxin B1 is degraded by dark reaction at 25-55 C. and pH 3.0-9.0. The Loigolactobacillus coryniformis subsp. coryniformis 523L5 has good growth performance, high acid production ability, strong salt tolerance and acid tolerance, and may tolerate about 7% salinity. It may grow under the condition of pH 4.5 and has good fermentation performance. The fermentation broth can efficiently degrade Aflatoxin B1 under acidic (pH 5.0-7.0) and high temperature (50-55 C.) conditions, and the highest degradation rate can reach 88.13% at 40 C. and pH 7.0.
