Chemical factors in the germination of spore-bearing aerobes. The effects of amino-acids on the germination of <i>Bacillus anthracis</i>, with some observations on the relation of optical form to biological activity

Abstract

The first paper of this series It thus became possible to study the effects of amino-acids on germination, since the optimum concentration expected for many of them, of the order of 100 mg./l. on the basis ofthe optimum concentration of gelatin hydrolysate (0-25 %), was much greater than that of the adenosine. Observations on amino-acid requirements were therefore not likely to be vitiated by trace impurities in the adenosine, which was, necessarily, a natural product.
