NOVELTY - Producing biocatalytic agents comprises (a) sterilizing support preloaded with nutrient medium, (b) inoculating on the support, (c) sequential feeding the medium and vital growth factors, (d) microbial production, (e) creating pre-lethal stress limiting conditions, (f) conservatory sporulation, (g) feeding growth factors, (h) drying sporulated microbial biomass, (i) verifying the stability and reviving the biocatalytic activity after sporulation, and (j) conditioning.    USE - The microbial biomass is useful for the treatment of arable land, effluents and purification equipments, drains for evacuating domestic and factory waste water, water catchment areas or for carrying out the metabiosis of organic solids and production of enzymes (all claimed).    ADVANTAGE - The process provides the microbial biomass, which exhibits maximum produced quantity of 200-300% with respect to the microbial biomass obtained by conventional process, continuous and controlled culture for big industrial purpose, rapid regeneration of viable spores of microorganisms, and high biocatalytic persistence of 5-7 times more compared to microbial biomass obtained by conventional process. The process is simple, rapid and inexpensive.    DETAILED DESCRIPTION - Continuous process for producing biocatalytic agents by solid continuous culture on biodegradable or non-biodegradable absorbent solid support, where the process takes place into a succession of operations, comprises (a) sterilizing support preloaded with nutrient medium, (b) inoculating on the sterilized support, (c) sequential feeding of the nutrient medium and vital growth factors, (d) microbial production by growth, proliferation with intrasupport saturation of pores, interstices and cavities of the support, then growth and peripheral proliferation, (e) creating pre-lethal stress limiting conditions at the end of the proliferation, (f) conservatory sporulation, (g) feeding growth factors on the sporulated microbial biomass under pre-lethal stress limiting conditions, (h) drying sporulated microbial biomass, (i) verifying the stability and reviving the biocatalytic activity after sporulation, and (j) conditioning biocatalytical agents thus supported. An INDEPENDENT CLAIM is included for the microbial biomass obtained by the process, where the biomass has four main characteristics which are expressed by: maximum produced quantity of 200-300% with respect to the microbial biomass obtained by conventional process, continuous and controlled culture for big industrial purpose, rapid regeneration of viable spores of microorganisms, and high biocatalytic persistence of 5-7 times more compared to microbial biomass obtained by conventional process.
