TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The plant-fiber degrading enzyme and organic substrate degrading enzymes are cellulases, amylases, glucanases, hemicellulases, proteases, chitinases, and/or lipases. The composition also comprises (wt.%) source of microorganisms (0.01-3), inorganic source of microbial electron acceptors and ammonium-free source of inorganic nutrient nitrogen for anaerobic microorganisms, source of complex biologically hydrolysable nutrient phosphorus (0.25-15), building agent (0.01-7, preferably 0.05-7), source of chelating agents (0.01-5). The source of microorganisms produces plant-fiber and organic-substrate degrading enzymes. The source of microorganisms is dehydrated cultures, freeze-dried cultures, encapsulated cultures, and/or spores. The source complex biologically hydrolysable nutrient phosphorus is ringed metaphosphate and/or linear polyphosphates. The source of microorganisms producing plant-fiber and organic-substrate degrading enzymes are resistant to or tolerant of mechanical abrasion, compaction, heat, steam, freezing temperatures and pressure. The inorganic source of microbial electron acceptors and ammonium-free source of inorganic nutrient nitrogen for anaerobic microorganisms is sodium nitrate, manganese nitrate, manganese nitrate tetra-hydrate, and/or manganese nitrate hexa-hydrate. The source of complex biologically hydrolysable nutrient phosphorus is sodium hexa-metaphosphate, sodium tri-metaphosphate, potassium tri-polyphosphate, and/or tetra-sodium pyrophosphate. The chelating agents are citric acid, humic acid, fulvic acid, sodium citrate, nitrilo-tri-acetic acid (NTA), and/or ethylene di-amine tetra-acetic acid (EDTA). The binding agent is (pre-gelled) starch, liquid or dried molasses, granulated sugar, (dried) corn syrup, guar gum, xanthum gum, locust bean gum, barley malt extract, vegetable oils or fats, animal oils or fats, lards, glycerin, gelatine, bentonite, montmorillonite, kaolinite, or calcium carbonate. The composition is made in a form of granules, briquettes, pellets, blocks, tablets, and/or capsules. The composition is applied to the environmental media at 0.1-1000g per kg of environmental media.
