<i>Arthrospira</i>-based compositions and uses thereof

摘要

The present invention concerns a composition comprising physiologically stressed Arthrospira maxima for use as a biocide and/or therapeutic. The invention also concerns a method for preventing or treating an infection or infestation of a subject by an organism, wherein the method comprises the step of administering to the subject an effective amount of a composition comprising physiologically stressed Arthrospira.

主权项

1. A method for preparing a topical Arthrospira-based composition, said method comprising the steps of:
(1) growing Arthrospira; (2) as a separate step, physiologically stressing the Arthrospira by a stressing technique selected from the group consisting of: depriving nutrients, depriving light, dehydrating and removing up to 80% of liquid within which the Arthrospira is being grown until substantially all of the Arthrospira enters an anabiotic state, but not freeze drying the Arthrospira, and obtaining stressed Arthrospira; and (3) combining a fungicidally or bactericidally effective amount of the stressed Arthrospira with a carrier, a solvent, a base or an excipient suitable for topical administration to the subject to form a the topical Arthrospira-based composition comprising at least 0.01% weight/weight stressed Arthrospira, and wherein the stressed Arthrospira of the composition comprises a filament material selected from the group consisting of: intact Arthrospira filaments, segments of Arthrospira filaments and disrupted Arthrospira filaments.
