Abstract
At temperatures upwards of 36[degree]C pediococci become increasingly prominent among the lactic microflora of ryegrass silage and at 44CC lactobacilli are rarely found. This effect is not peculiar to the silage environment since it has been demonstrated in common laboratory media also. It may be explained simply on the basis of the greater capacity of pediococci for growth at the higher temperatures within the range studied. A possible significance of this phenomenon in relation to practical silage making is not presently apparent.
