NOVELTY - A population (P1) of micro electron acceptor phosphorus accumulating organisms (MEAPAOs) adapted to grow in a cell, tank, pond or unit comprises organic waste without a physically separated and defined anaerobic environment, where oxygen is maintained at less than 2 mg/l of dissolved oxygen, the concentrations of nitrate and nitrite are each less than 5 mg/l, and the MEAPAOs are capable of increased conversion of at least one nutrient from soluble to particulate form in the cell, tank, pond or unit.    USE - For treating a population of micro-organisms (claimed); for the biologically mediated treatment of solid and liquid organic wastes, particularly animal farm wastes including the removal of nutrients from such wastes such as phosphorus and nitrogen.    ADVANTAGE - The process operates at low electron acceptor concentrations while maintaining high quantities of diverse populations of microorganisms. The process addresses many of the problems associated with municipal, domestic, industrial, food industry, animal husbandry and other organic wastes; provides an attractive and efficient means to resolve ecological problems associated with the treatment of organic wastes. The process solve the odor emission problem common to organic wastes as well as high nutrient effluent discharge concentrations through the efficient, odorless, biologically mediated conversion of waste excrement materials or vast array of other organic wastes into stable, economically and/or ecologically beneficial materials; transformation of organic wastes into suitable materials for recycling to the environment; capability of accumulating significant levels of particulate phosphorus even when living in environments which have low concentrations of electron accepting substances (such as oxygen, nitrite and nitrate) with and/or without subjecting the phosphorus accumulating organisms to discrete anaerobic conditions in physically defined and separate environment; create biologically active and/or nutrient rich organic soil.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a population of micro-organisms comprising a population of MEAPAOs (P1).
