Preguntas

  1. Is the BSM supplement autoclavable with BSM agar? Or is it heat sensitive? Should I add the supplement before or after autoclaving bsm agar?

    1 respuesta
    1. This supplement is heat-sensitive and must not be autoclaved. The procedure for preparation of BSM agar is featured in the BSM agar 88517 datasheet: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/199/251/88517dat.pdf

      This procedure explains that the BSM agar base is to be autoclaved, while the supplement is to be added after cooldown. The supplement is prepared by adding sterile water, in order to avoid compromising the sterility of the prepared complete medium.
