DEXTRAL AND SINISTRAL FORMS OF BACILLUS 455 In the light of all these experiments it is certain that the dextral (D-l) and sinistral (L-l) strains of Bacillus mycoides under examina- tion possess distinctly different relations of growth to temperature and that these distinctions are retained both in solid and in liquid medium, both in R and S modifications. However, are these observations suffi- cient for the belief that the differences observed are actually connected with the dextrality and sinistrality of the strains studi

Temperature relation of growth in the smooth sinistral (L-l, L-3) and dextral (D-l, D-2, D-3) strains of Bacillus mycoides in the liquid medium. Each point represents an average for three observations. answer this question it is necessary to observe a great number of various strains of Bacillus mycoides. To this end one additional sinistral strain, L-3, and two new dextral inverse strains, D-2 and D-3, were chosen. All these strains had been cultivated under laboratory conditions for five years. S-modifications of various strains were used for experi- mentation for the reason that it is easier to prepare the suspension for inoculation from them. The results of experiments carried out in liquid medium with five strains of Bacillus mycoides of different origin are given in Fig. 5. It may be pointed out that the differences in the.
