Abstract: Flocculated bacterial cells are utilized as high-density crop inoculants and delivery systems for one or more agriculturally beneficial microorganisms. The flocculated form of bacteria, such as Azospirillum and Rhizobium, possess superior survivability under storage, as a seed coating and mixed seed priming media. Other microorganisms may be co-flocculated with the aforementioned bacteria, thereby providing a crop inoculant for delivery of multiple agriculturally beneficial microorganisms.

Abstract: A method for rendering water-insoluble materials water-soluble is provided. The method is useful for solubilizing substantially water-insoluble bioactive materials such as drugs. This is accomplished by forming a non-covalently bonded complex between the drug and a polyalkylene oxide polymer end capped with an alkyl or olefinic group which is soluble in both water and an organic solvent. This is carried out by combining the desired medicinal agent with the polymer is an organic solvent, removing the solvent and dissolving the complex in water or aqueous buffer. When the organic solvent is evaporated, a solid complex is recovered which is water-soluble. Methods of treatment with the complexes are also provided.
