Reisolation and growth conditions of bacillus agar-exedens.
Several agarolytic Bacillus strains have been isolated. The properties agree with those described by Wieringa (1941) for Bacillus agar-exedens. These strains are the first reisolates since the original cultures were lost. A second group of isolates is related to the agarolytic B. palustris var. gelaticus of Sickles and Shaw (1934). B. agar-exedens requires carbohydrates for growth. In mineral-glucose media growth is inhibited by peptone at pH values of about 7 or less. Under alkaline conditions no inhibition by peptone is observed. A method for the enrichment of B. agar-exedens is described.
