Oxidation of Nitrated Cellulose by the Microbial Community of Active Sludge

The oxidation of native and nitrocellulose (NC) treated with ultraviolet radiation and ozone (UV + ozone) by the community of active sludge (AS) microorganisms of treatment facilities, as well as by the combination of AS with sulfate-reducing Desulfovibrio desulfuricans VKM B-1388 and microscopic fungi Fusarium solani VKM F-819, is studied. It is shown that the use of pretreatment significantly increases the degree of decomposition of NC during its subsequent biodegradation by the symbiosis of AS microorganisms with D. desulfuricans and F. solani . The use of mutagenic treatment of AS with nitrosomethyl urea (NMU) allows the biocenosis of AS microorganisms with a contaminant-NC to maintain a high oxidizing ability with good sedimentation properties for 65 days of incubation. The degree of NC decomposition is 24.36%.
