  This invention relates to a biological indicator derived from a composition comprising: a host organism comprising a spore forming bacteria; a reporter gene for producing an indicator enzyme; a regulatory gene; and a vehicle for inserting the reporter gene and the regulatory gene in the host organism; the host organism bearing a transposable genetic element in its genome for inserting an insertion sequence in the regulatory gene; the insertion sequence comprising a transposase, a pair of terminal inverted repeat sequences, and at least one open reading frame for expressing the transposase. The vehicle may be taken up by the host organism. The insertion sequence may be inserted in the regulatory gene. The host organism may undergo sporulation to form the biological indicator. A process and an apparatus for using the biological indicator are disclosed.
