(A) an isolated strain of Burkholderia sp. A 396 (NRRL Accession No. B-50319);
(B) a C1-C8 paraben, and (C) a C2-C17 alcohol.
2 . The composition according to claim 1 , wherein said C1-8 paraben is present in the amount of about 0.01-5%, the C2-C17 alcohol is present in the amount of about 0.001-10%.
3 . A method for obtaining a C1-C8 paraben comprising
(A) providing a composition comprising an isolated strain of Burkholderia sp. A 396 (NRRL Accession No. B-50319);
(B) providing a C2-C17 alcohol;
(C) incubating the composition of (A) and the alcohol of (B) for a time and at a temperature sufficient to produce said C1-C8 paraben; and
(C) isolating said C1-C8 paraben.
4 - 7 . (canceled)
8 . The method of claim 3 , wherein said C1-C8 paraben is selected from butyl, hexyl and octyl paraben.
9 .
