TECHNOLOGY FOCUS - BIOLOGY - Preferred Composition: The fibrous vegetable material (10-90 (preferably 20-45) wt.%) of (II): is alfalfa (preferred), hemp, linen residue, beet crown or leguminous plants of horse bean. The binding agent is: of vegetable origin (which is a mixture of starch and proteins) or synthetic origin. The vegetables binding agent (25-47 wt.%) is vegetables, which give starchy compound (rice, potatoes, manioc, corn, wheat, barley, oats, hop or tapioca, preferably cereal flour). (II) further comprises a second carbonated binding agent of vegetable origin. The other carbonated binding agent (0-5 wt.%) is a natural hydro-soluble polymer (vegetable juices which is produced by alfalfa or other vegetables comprising graminaceae, polysaccharides product from molasses, cane sugar and/or sugar beet, the products results from a fractionation of vegetable juices in particular hydrolysate and serums). The binding agent of synthetic origin is (preferably polyvinyl alcohol (5-40%)) optionally substituted for the binding agent of vegetable origin. The plasticizer (1-30 (preferably 3-20) wt.%) is: a biodegradable hydro soluble organic compound of natural or synthetic origin. In the product, mineral charges (clay (preferably kaolinite or montmorillonite), talcs, silicones, calcium carbonates or titanium oxide) (0-15 (preferably 2-10) wt.%) and lubricating agent (zinc stearate or magnesium stearate) (0.5-5 wt.%) are added to (II). (II) comprises 5-15 wt.% of water. Preferred Components: The nutrients and additives of bacteria growth (pectin, yeast extract, cellulose and hemicellulose, polysaccharides, amino acids or enzymes) are added to (II). (C) containing the bacteria is 2-20 wt.% of (I). In (I), if the nutrients and additives are added to (II) the bacterial growth. The amino acid of (B) is 21 amino acids. The quantity of amino acid deposited on the surface of (A) is 100-5000 g/m2. (B) contains: polysaccharides; mineral salts; and nutriments and additives of bacterial growth. (B) is 10-25 wt.% of (I). (I) further contains clay (0-10 wt.%). The families of bacterial colonies placed within the conditioning layer are aerobic strains (preferably bacteria, yeasts, or fungi of the nitrogen and carbon cycle). The quantity of the aerobic strains is 0.0001-2 wt.%. The aqueous medium comprising bacteria is 2-20 wt.% of (I). The aerobic strains are of genus Micrococcaceae, Lactobacillaceae, Bacillaceae, Nesseriaceae, Enterobacteriaceae, Azotobacteriaceae, Rhizobiaceae, Nitrobacteriaceae, Thiobacteriaceae, Pseudomonadaceae (like bacterias), Pseudomonadales, Pseudomonas, Nitrosomonas, Nitrobacter, Thiobacillus, Vibrio, Acetobacter, Azotobacteriacae: Azotobacter, Beijerinckia Achromobacteriacae: Achromobacter, Flavobacterium Enterobacteriacae: Aerobacter, Serratia Lactobacillacaes: Lactobacillus, Corynebacteriacae: Arthrobacter Bacillacae: Bacillus, of the actinomycetes: Actinomycetacae: Nocardia, Pseudonocardia, of the mushrooms: Mucoralae: Rhizopus, Protoascomycetae (yeasts), Candida, Torula, Rhodotorula, Cryptococcus, Torulopsis, Euascomycetes (moulds), or Aspergillus.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Claimed): Preparation of (I) comprises: drying and optionally crushing by dehydration, and compacting a vegetable material; mixing the fibrous vegetable material with binding agent, plasticizer and optionally additives; compounding, plastifying, and forming (II) by the techniques of compound extrusion and calendaring as: sheet, film, tube, profile, molding by injection; forming the lower part of (A); preparing a formulation comprising an amino acid to constitute coating; coating the formulation comprising an amino acid on the sides of (A); preparing and introducing bacterial colonies, aerobic yeasts or aerobic fungi to be conditioned in (A) in a nutritive liquid medium; and air-tight closing of (A) by a sheet optionally coated with an amino acid and cutting of (A) formed. Preferred Components: The hydrosoluble plasticizer is polyols (preferably glycerol, sorbitol, ethylene glycol, diethylene glycol, propylene glycol, adonitol, dithioerythritol, dithiothreitol, galactitol, inositol, mannitol and/or xylitol). The additive is constituted by mineral salts. The mineral salts are nitric and/or phosphates, phosphates and/or ammonia sulfate, magnesium, calcium, sodium, manganese, molybdenum, iron, copper or zinc. EXAMPLE - Typical composition comprises (%): Luzerne (20), wheat flour (45.2), glycerol (3.5), sorbitol (4.9), clay (5.5), magnesium stearate (3.5), lactate sodium (7) and water (10.4).
