A microbiological screening procedure was used to assess the potential of each of the straight chain members of the series of fatty acids, formic to lauric inclusive, as silage additives. Thirty‐four pure cultures of microorganisms were subjected to serial dilutions of each of the acids in broth buffered at unit pH intervals between 3 and 6 inclusive. All the fatty acids of the series appeared to have potential; the lower members (C 1 ‐C 7 ) prevented the growth of spore‐bearing bacteria and the higher acids had more general antimicrobial effects. A consistent feature of the data obtained was the increase in antimicrobial activity with a decline in pH.
