Environmental Fate of Hexabromocyclododecane (HBCD) The Degradation Pathway

Introduction Hexabromocyclododecane (HBCD) is currently undergoing risk assessment in the EU (Existing Substances Regulations 793/93/EEC). During the risk assessment process, the environmental persistence of HBCD was investigated. In previous studies (Davis et al 2005, 2006a), the biodegradation of HBCD was reported to occur in freshwater aquatic sediments and digester sludge. Using C-labelled ...

Degradation of amino acids by the mixed rumen microbial population.

Degradation of physiological quantities of amino acids by rumen microbes was determined under both in vitro and in vivo conditions. In vitro rate constants for EAA indicated that Arg and Thr were rapidly degraded (.5 to .9 mM/hr); Lys, Phe, Leu and lie formed an intermediate group (.2 to .3 mM/hr); and Val and Met were least rapidly degraded (.1 to .14 mM/hr). In vivo EAA degradation rates were...

AN INDEX REPRESENTING STRUCTURE-CATABOLIC FATE RELATIONSHIPS OF AMINO ACIDS

Based on the Randic suggestion of the resolution of a structure into shape, size, and function an index representing structure-catabolic fate relationships of amino acids is constructed. The index obtained by multiplying three factors; (nb2 + nr), nc and M; representing shape, size and function respectively, where nb2 = number of double bonds, nr = number of rings, nc = number of carbon atoms, ...
