UMl films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer. The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction. In the unlikely event that the author did not send UMl a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing from left to right in equal sections with small overiaps.

Delineation of Subject An acylase is an enzyme vhlch catalyzes the hydrolysis of acylamino acids; that is, speeds up the following reaction: R • - CO- NH- CHR- COOH +H2O ^ R • - C OOH -f NH3- C HR- COO" This thesis describes an investigation of the properties end possible physiological importance of an acylase or acylasee from the acid producing bacterium, Lactobacillus arabinosus.
