NOVELTY - Treating waste using sulfide-utilizing, organic-digesting, nitrogen-digesting and/or phosphorus-absorbing bacteria, useful in the biological removal of organic carbon, nitrogen and phosphorus compounds from wastewater, is new.    USE - The processes and compositions are useful for wastewater treatment, in particular for treating organic waste by the biological removal of organic carbon, nitrogen and phosphorus compounds from wastewater.    DETAILED DESCRIPTION - A process for treating waste comprises adding a first inoculum having sulfide-utilizing bacteria to a sulfide-rich organic waste to produce a lowered-sulfide waste, adding a second inoculum having organic digesting bacteria to produce a digested waste, and adding to the digested waste at least one of a third inoculum to produce a lowered nitrogen waste, and a fourth inoculum having phosphorus absorbing bacteria to produce a phosphorus enriched bacteria fraction and a phosphorus depleted waste fraction. The sulfide-rich organic waste in the process cited above comprises a concentration of at least one nitrogen and phosphorus contaminant. The third inoculum comprises bacteria capable of converting a nitrogen-containing compound to N2. The process also comprises adding a first inoculum comprising sulfide-utilizing bacteria to a sulfide-rich and nitrogen-rich organic waste, to produce a lowered-sulfide waste, adding a second inoculum comprising organic digesting bacteria to the lowered-sulfide waste to produce a digested waste, and adding a third inoculum comprising bacteria capable of converting a nitrogen-containing compound to N2, to the digested waste to produce a lowered nitrogen waste. The process alternatively comprises adding a first inoculum comprising sulfide-utilizing bacteria to a sulfide-rich and phosphorus-rich organic waste, to produce a lowered-sulfide waste, adding a second inoculum comprising organic digesting bacteria to the lowered-sulfide sulfide waste to produce a digested waste, and adding a third inoculum comprising phosphorus absorbing bacteria to the digested waste to produce a phosphorus enriched bacteria fraction and a phosphorus depleted waste fraction.
