TECHNOLOGY FOCUS - BIOLOGY - Preferred Process: The solid continuous culture is carried out in a horizontal incubator compartmentalized into three successive zones corresponding to phases of successive activities of zone 1 of inoculating the strain and production of microorganisms, zone 2 of sporulation followed by addition of future growth factors, zone 3 of drying of support bioloaded with spores or cysts, or in other forms of conservatory resistance. The shifting of the bioloaded support in the incubator is done continuously from the first to the last zone, by a device consisting of a flexible conveyor element of flat and perforated surface, capable of receiving all forms of culture support moved by motor. The inoculum is seeded by spraying on the support. The nutrient medium, vital and growth factors specific to the culture strain are fed sequentially, the gaseous vital elements are fed by blowing. The continuous production of microorganisms is a succession of growth cycles and intrasupport proliferation continuously followed by cycles of peripheral colonization of the support. The produced supported microbial biomass is placed in sporulation state, or conservatory resistance by creating strain-specific pre-lethal stress limiting conditions. The feeding of future growth factors on spores is carried out under strain-specific pre-lethal stress limiting conditions. The drying of the sporulated microbial biomass is made in accordance with conditions caring the spores, by blowing dehydrated air. Preferred Components: The microorganisms are bacteria, yeasts or fungi. The process is adaptable to various microorganisms comprising strains of Azobacteriaceae, Pseudomonaceae, Rhizobiaceae, bacteria of the genus Klebsiella oxytoca, Baciilus thuringiensis, Bacillus sphaericus, biocenosis of different medium, bacteria of the hydrolytic metabiosis, acetogenesis or methanogenesis, microorganisms producers of enzymes such as Bacillus amyloliquefaciens, Bacillus licheniformis, Aspergillus niger and Aspergiiius oryzae.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The biodegradable or non-biodegradable absorbent solid support is natural and/or synthetic origin, where the support is not directly fermentable by microorganisms. The support comprises thread form, flat two-dimensional form, lignocellulosic fibers comprising fibers of flax, jute, hemp, sisal, kenaf, coconut, cotton and wood or biodegradable synthesis of polymer fibers comprising polycaprolactone, certain polyesters, polyurethane, polylactic acid (PLA), or non-biodegradable synthetic polymers comprising polyethylene, polyamide, polyester, and/or polyether. The biodegradable support of thread form or flat two-dimensional form has a biodegradability differential between the core of the support and its periphery. The support is granulated two-dimensional form, constituted of crushed porous materials or in granulated form, biodegradable or non-biodegradable polymer type, of natural or synthetic origin, or a composite of the two types of polymers. The biodegradable absorbent solid support has a capacity of water retention and liquid of 50-85%. EXAMPLE - No suitable example given.
