Abstract

The invention relates to compounds, compositions and methods for biofilm disruption and prevention. In particular, the invention relates to pharmaceutical compositions for the disruption of biofilm and prevention of biofilm in patients. The invention also relates to anti-biofouling compositions for the disruption of biofilm and prevention of biofilm on surfaces. The invention also relates to the removal of biological material from surfaces. The compositions of the invention include microbial deoxyribonucleases.

Claims (15)

1. An anti-biofouling composition for disrupting or preventing a biofilm formation comprising a biofilm-modulating dose of an isolated NucB deoxyribonuclease, an enzyme, and an anionic or non-ionic surfactant, wherein the NucB deoxyribonuclease is the amino acid sequence of SEQ ID NO: 4 or a deoxyribonuclease sequence that is at least 95% identical to SEQ ID NO: 4, and wherein said composition is formulated as a washing powder or a cleaning solution.

2. The anti-biofouling composition of claim 1 , wherein the isolated NucB deoxyribonuclease is a Bacillus NucB deoxyribonuclease.

3. The anti-biofouling composition of claim 2 , wherein the Bacillus NucB deoxyribonuclease is a Bacillus licheniformis NucB deoxyribonuclease.

4. The anti-biofouling composition of claim 3 , wherein the Bacillus licheniformis NucB deoxyribonuclease is a Bacillus licheniformis strain EI-34-6 NucB deoxyribonuclease.

5. The anti-biofouling composition of claim 1 , which is formulated as a washing powder.

6. The anti-biofouling composition of claim 1 , which is formulated as a cleaning solution.

7. The anti-biofouling composition of claim 1 , which comprises an anionic surfactant.

8. The anti-biofouling composition of claim 7 , wherein the anionic surfactant is selected from the group consisting of sodium lauryl sulfate, sodium dodecyl benzene sulphonate, alkyl aryl sulphonates, N-lauroyl sarcosine, and sodium, potassium and ethanolamine salts of N-lauroyl, N-myristoyl, or N-palmitoyl sarcosine.

9. The anti-biofouling composition of claim 1 , which comprises a non-ionic surfactant.

10. The anti-biofouling composition of claim 9 , wherein the non-ionic surfactant is selected from the group consisting of condensation products of ethylene oxide with fatty acids, fatty alcohols, fatty amides, polyhydric alcohols, and polypropyleneoxide.

11. The anti-biofouling composition of claim 1 , further comprising one or more of an antibacterial compound, an antiparasitic compound, an antifungal compound, and an antiviral compound.

12. The anti-biofouling composition of claim 11 , wherein the antiparasitic compound is one or more of a benzazole, an azole, a macrocycle, pyrantel pamoate, diethylcarbamazine, niclosamide, praziquantel, melarsoprol, and eflornithine.

13. The anti-biofouling composition of claim 11 , wherein the antifungal compound is one or more of an azole, a macrocycle, an allyl amine, an echinocandin, polygodial, ciclopirox, tolnaftate, benzoic acid, undecylenic add, flucytosine and griseofulvin.

14. The anti-biofouling composition of claim 11 , wherein the antibacterial compound comprises one or more of parahydroxy benzoic acid esters.

15. The anti-biofouling composition of claim 1 , wherein the composition further comprises water.
