Salix nigra bark of the tree contains salicylic acid, a chemical compound similar to aspirin (acetylsalicylic acid). It may also be used as an environmental restorative. Swamp trees in general are, by necessity, good at surviving and thriving in areas where highly mobile environmental toxins are present. Black Willow is very resistant to herbivory and flooding and is also a fantastic erosion control tool. Thus, it is useful for any sort of marshland stabilization or restorative as long as the roots don’t penetrate any clay liner that may be in place. In a relatively extensive phytoremediation study, "Salix nigra" demonstrated some success
Cob(I)yrinic acid a,c-diamide adenosyltransferase as: Cob(I)yrinic acid a,c-diamide adenosyltransferase In molecular biology, cob(I)yrinic acid a,c-diamide adenosyltransferase (also known as ATP:cob(I)alamin adenosyltransferase or ATP:corrinoid adenosyltransferase) is an enzyme which catalyses the conversion of cobalamin (vitamin B12) into one of its coenzyme forms, adenosylcobalamin (coenzyme B12, AdoCbl). Adenosylcobalamin is required as a cofactor for the activity of certain enzymes. AdoCbl contains an adenosyl moiety liganded to the cobalt ion of cobalamin via a covalent Co-C bond. ATP:cob(I)alamin adenosyltransferases are classed into three groups: CobA-type, EutT-type and PduO-type. Each of the three enzyme types appears to be specialised for particular AdoCbl-dependent enzymes or for the de novo
