PURPOSE:To biologically obtain iron having uniform particle size using a microbial cell SKS from a substance containing an iron based soil. CONSTITUTION:Iron is extracted utilizing action of microbial cell SKS by mixing iron based soil with a microbial cell SKS consisting of mixed bacteria of a SKS-I bacterium belonging to gram-positive endospore-forming bacterium (mesophile), SKS-2 bacterium belonging to gram-positive endospore-forming bacterium (thermophile), SKS-3 bacterium belonging to gram-positive asporogenous rod-shaped bacterium, SKS-4 bacterium belonging to Actinomyces (thermophile), SKS-5 bacterium belonging to Actinomyces (mesophile), SKS-6 bacterium belonging to catalase-positive and gram-positive coccus, SKS-7 bacterium belonging to Enterobacteriaceae, SKS-8 bacterium belonging to fungus and anaerobic SKS-9 bacterium belonging to strict anaerobic endospore-forming rod and then allowing the mixture to stand. |
