“…Sulfamic acid (H 2 NSO 3 H) is a strong acid that has found uses as a herbicide, a component of flame‐retardants and is used in the removal of limescale from industrial tanks, as well as in the manufacture of the non‐nutritive sweetener cyclamate and thus finds its way into the environment (Metzger, 1994). It would appear, potentially, to be a ready source of sulfur and nitrogen for growth of microbes as hydrolysis of its sulfur–nitrogen bond would, theoretically, produce ammonia and sulfate.…”

A bacterium able to utilize sulfamate as N-source for growth was isolated from soil and identified as a Mycobacterium sp. An apparently previously unrecorded enzyme, sulfamate hydrolase (EC 3.10.1.-), converts sulfamate to equimolar amounts of ammonia and sulfate. This enzyme was purified to homogeneity and had a Km for sulfamate of 26.36 +/- 4.01 mM. Its Specificity Constant value, 74 M(-1) s(-1), was low, indicating that it was not a particularly good catalyst for this reaction and it may be a hydrolase recruited to this role from some other reaction sequence. However, under equivalent conditions it showed no detectable action on the other sulfamates, cyclamate and sulfamoylbenzoate, or on urea or methylamine.

“…Sulfamate (H P N^SO Q 3 ) is used mainly as a precursor for the arti¢cial sweetener, cyclamate (cf. [5]) as well as in industrial and household descaling [6]. Sulfamate can thus be expected in many sewage works.…”

Bacterial cleavage of nitrogen to sulfone bonds in sulfamide and 1H-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide: formation of 2-nitrobenzamide byGordoniasp.

Pure cultures of aerobic bacteria were isolated which could utilize sulfamate, sulfamide or 1H‐2,1,3‐benzothiadiazin‐4(3H)‐one 2,2‐dioxide (BTDD) as sole source of sulfur for growth and thus cleave a N–S(O)x bond. The molar growth yields indicated that each source of sulfur was utilized quantitatively. This was confirmed directly for Gordonia sp. strain BT2 utilizing BTDD, which was converted quantitatively via an unidentified intermediate to 2‐nitrobenzamide. Another isolate, strain BT1, could utilize saccharin to yield salicylamide, thus cleaving both the N–S(O)x and C–S(O)x bonds.
