Abstract

Provided herein are secretory compositions/cocktails derived from a novel, extremophilic fungal species cultured, isolated, characterized and sequenced herein. Said novel, extremophilic fungal species may be exploited to produce a secretory compositions/cocktails which comprise a unique mixture of thermo-tolerant, stable enzymes capable of digesting cellular and genetic material in its surroundings under extreme temperatures. Such secretory compositions/cocktails may be useful as cleaning and sterilization solutions against biofilm, urine, yeast, bacterial, or viral contamination. Other uses include, but are not limited to, urea removal, fertilizer wastewaters, wastewater reclamation for life support systems in space, pH control, source of ammonia and carbon dioxide, starch digestion, biofuel production, as pharmaceuticals, and medical treatments such as wounds, skin disorders, or nail disorders.

First claim

We claim:

contacting the wound comprising the microorganisms with a composition comprising one or more enzymes derived from TM-417, thereby reducing the amount or the activity of the microorganisms.

2. The method of claim 1 , wherein the one or more enzymes comprise at least one enzyme selected from the group consisting of urease, DNase, RNase, exonuclease, endonuclease, ribonuclease, amylase, acetoin reductase, an indole-3-acetamide hydrolase, a tryptophan monooxygenase, an acetolactate synthetase, an α-acetolactate decarboxylase, a pyruvate decarboxylase, a diacetyl reductase, a butanediol dehydrogenase, an aminotransferase, a tryptophan decarboxylase, an amine oxidase, an indole-3-pyruvate decarboxylase, an indole-3-acetaldehyde dehydrogenase, a tryptophan side chain oxidase, a nitrile hydrolase, a nitrilase, a peptidase, a protease, an adenosine phosphate isopentenyltransferase, a phosphatase, an adenosine kinase, an adenine phosphoribosyltransferase, CYP735A, a 5′ribonucleotide phosphohydrolase, an adenosine nucleosidase, a zeatin cis-trans isomerase, a zeatin O-glucosyltransferase, a β-glucosidase, a cis-hydroxylase, a CK cis-hydroxylase, a CK N-glucosyltransferase, a 2,5-ribonucleotide phosphohydrolase, an adenosine nucleosidase, a purine nucleoside phosphorylase, a zeatin reductase, a hydroxylamine reductase, a 2-oxoglutarate dioxygenase, a gibberellic 2B/3B hydrolase, a gibberellin 3-oxidase, a gibberellin 20-oxidase, a chitosanase, a chitinase, a β-1,3-glucanase, a β-1,4-glucanase, a β-1,6-glucanase, an aminocyclopropane-1-carboxylic acid deaminase, chitosanase, a cellulase, a lipase, a lignin oxidase, a glycoside hydrolase, a phosphatase, a nitrogenase, a nuclease, an amidase, a nitrate reductase, a nitrite reductase, an amylase, an ammonia oxidase, a ligninase, a glucosidase, a phospholipase, a phytase, a pectinase, a glucanase, a sulfatase, a xylanase, an endocellulase, an exocellulase, a β-glucosidase, phospholipase, acetate kinase, phosphotransacetylase, lactate dehydrogenase, pyruvate decarboxylase (PDC), alcohol dehydrogenase (ADH), xylose isomerase, xylulokinase, L-arabinose isomerase, L-ribulose-5-phosphate 4-epimerase, a glycan strand-cleaving enzyme/glycosidase, N-acetylglucosaminidase, acetylmuramyl-L-alanine amidase, lysozyme, lytic transglycosylase and peptidoglycan endopeptidase.

3. The method of claim 1 , wherein the one or more enzymes comprise two or more enzymes.

4. The method of claim 1 , wherein the one or more enzymes have at least about a 25-fold increase in specific activity when purified using size exclusion chromatography in combination with an affinity based membrane purification system, at least about a 100-fold increase in specific activity when purified using size exclusion chromatography in combination with an affinity based membrane purification system.
