Lugol iodine solution was compared with glutaraldehyde as a preservative for marine bacteria. Direct counts with the fluorochrome 4',6-diamidino-2-phenylindole show no significant difference between the preservatives, but the use of Lugol solution has several advantages over glutaraldehyde, especially in the
