Abstract
Abstract Cyanides, thiocyanates and metal cyanide complexes present in an aqueous solution can be biologically degraded by certain mutant strains of the species Pseudomonas paucimobilis. Such microorganisms are useful in the biological treatment of cyanide-containing wastewaters. Pseudomonas paucimobilis mudlock was deposited at the ATCC on Nov. 3, 1982, and granted accession No. 39204.
