Surfactants and detergents having strong detergency on the basis of the actions of microorganisms without resort to any chemicals, being widely applicable to subjects over a broad scope and being easy in handling. These surfactants and detergents contain a complex solution of microorganisms and enzymes having (a) aerobic microorganisms, (b) anaerobic microorganisms and (c) at least one basidiomycetes belonging to the <i>Pleurotus</i> family living in symbiosis and containing enzymes originating in the metabolites thereof which is obtained by grinding proteins having animal proteins as the main components; mixing the ground matter with cereals and yeasts; fermenting the resultant mixture; heating the fermented matter;, grinding the heated matter; adding a lactic acid bacterium liquid culture medium or a <i>Bacillus subtilis</i> liquid culture medium to the ground matter obtained in the above step;, effecting fermentation under aerobic conditions; in the culture medium cultured in the solution thus prepared, culturing (a) aerobic microorganisms and (c) at least one basidiomycetes belonging to the <i>Pleurotus</i> family; subsequently culturing (b) anaerobic microorganisms in the liquid culture medium; and then adding a plant-origin carbon source to the liquid culture medium to thereby effect metabolism with carbon-digesting enzymes.
