6 Aerobic Degradation by Microorganisms

Biotin and the Synthesis of Aspartic Acid by Microorganisms.

Considerable evidence is accumulating concerning the role of growth factors in the metabolism of amino acids by microorganisms. Koser, Wright, and Dorfman (1942) demonstrated a relationship between aspartic acid and biotin in that aspartic acid can serve as a partial substitute for biotin in the growth of Torula cremoris. Pantothenic acid influences the synthesis of tryptophane by Staphylococcu...

Enhanced degradation of isofenphos by soil microorganisms

Laboratory experiments were conducted to investigate the enhanced degradation of isofenphos [ 1methylethyl 24 [ethoxy[ (1-methylethyl)amino]phosphinothioyl]oxy] benzoate] in soil and to elucidate the microbiology of this phenomenon. [U-ring-'4CIIsofenphos was most rapidly degraded in Iowa cornfield soils that had a history of isofenphos insecticide use. Between 13 and 42% of an applied dose of ...
