Tomato juice inoculated with Cladosporium sp. or Penicillium sp. developed pH gradients with the upper portions near the mold mats having pH values near neutrality and the lower portions remaining more acid. Clostridium botulinum spores in these moldy tomato juices germinated, grew out, and produced toxin.
接种了枝孢属或青霉属的番茄汁形成了pH梯度,靠近霉菌垫的上部pH值接近中性,而下部则保持更酸性。这些发霉番茄汁中的肉毒梭菌孢子萌发、生长并产生毒素。
