摘要:
A stenophiluric media is provided containing at least one bio-limiting agent such as a copper, tin, nickel or alloy thereof. The media may be formed of a polymer such as a thermoplastic polymer. The polymer may be an epoxy resin, a polyester resin, a polyurethane resin or an aminoplast resin. The media may also be formed of an amalgam of naturally occuring tars and resins. In an embodiment, the polymer is a crosslinked polyepoxide prepared from an epoxy resin and a polyamine crosslinking agent. The media may also contain a nutrient source. The media is used to prevent fouling by applying a coating of the media to a substrate such as a the hull of a boat or ship, a culvert or piping or a surface in a fermentation vessel, and allowing a selected biomass to form on the media. The selected biomass produces allelopathic chemicals that prevent attachment of higher animals.

This invention relates to an article comprising a bio-supportive media which bio-degrades at a preferred rate, comprising at least one bio-limiting agent and at least one nutritional source on a substrate. The media may be characterized as a polymer, composite, or amalgam of commonly used materials. The invention relates to altering the physical/chemical composition of the media such that bio-degradation can occur at a specific, usually accelerated, preferred rate. Further, the bio-degradation rate may be managed and balance concurrently with the ability to provide for the exposure of integral component(s) which are bio-active. This relationship essentially provides for a managed release or managed availability of agent(s) which creates a hew set of ecological conditions. These sustained conditions can maintain a micro-habitat; a limited consort of species, often slime which, due to this ecological trophic niche position, can utilize innate allelopathic means to further protect their position and deter predation. The relationships of the nutrients, blo-limiters, and biomass comprise a unique micro-habitat as an interface which provides protection from corrosion and deterioration of the substrate upon which it is fixed, and limits the biomass accumulation on the surface thereby providing control of fouling by reducing higher order organism(s) attachments, which otherwise are very economically costly. Specifically the invention relates to modifying the media formation whether as a polymer or composite or amalgam such that the physical and chemical properties of the media are altered to become more degradable in the host habitat. This is accomplished by altering the polymerization or formation of the composite or amalgam to provide for increased inter-granular or molecular locations which permit enhanced bio-degradative activity. Then by occluding or interspersing physical or chemically an agent which has bio-active properties, the organisms of various species which may attach or be attracted to the surface can be limited by their nutrition and tolerance of bio-active preference without the need for toxification or mechanical removal of undesirable or unwanted organism as settlers. Once the community of selected organisms establishes a natural equilibrium with the host habitat any capacity for allelopathic protection of the biofilm can be utilized or enhanced by this new and unique biological community to its benefit through management of the media components.

Stenoprophiluric media provide for the creation and sustained well being of micro-habitats in uncontrolled host habitats in order to study the biological, biochemical and physical (morphological) properties of the organisms and their consortiums inherently and/or in relationship to competing or proximal micro-habitats as well. Given this in-situ method of study of these consortiums; sampling of metabolic bio-chemicals both primary and secondary is readily achieved. By providing this medium or platform for natural in-situ evaluation of varying host habitats and/or multiple sub-habitats ( micro-habitats) in the same host habitat, conditions and changing relationships can be evaluated; physically, biologically, and chemically. Evaluation enhancements by this method provides for the ability to sample discrete chemicals or groups of chemicals and/or compounds for easy bio-activity evaluation. Further, morphological and taxonomic evaluation of micro-habitats is permitted whereby, relationships and evaluation of changes in settling, growth, or mature bio-film formations can be readily accomplished.
摘要:
This invention relates to an article comprising a bio-supportive matrix comprising at least one bio-limiting agent and at least one nutritional source on a substrate. The invention also relates to the bio-supportive matrix and methods of using the matrix. The present invention can be used as a biological barrier to unwanted organisms, such as animals and plants, by producing allelochemicals that either kill or repel those organisms. The invention could be used as a coating on a vessel to prevent fouling of vessels. The invention may also be used to manufacture specific allelochemicals such as drugs or pharmaceuticals. The invention also relates to a method of preparing a bio-limiting ecological substrate useful as a means for producing allelochemicals, comprising the steps of providing a bio-supportive matrix as described above, and exposing the matrix to the environment, wherein the matrix is prepared to provide a biomass that produces the desired allelochemicals. The bio-supportive matrix provides a durable support layer for a biomass. The biomass may be selected to produce specific allelochemicals that have pharmaceutical or organism inhibiting properties.
