摘要: The growth rate and maximum biomass of Bacillus coagulans 2–6 were inhibited by lactate; inhibition sodium lactate was stronger than calcium lactate. differences protein expressions B. under the stress determined using two-dimensional electrophoresis coupled with mass spectrometric identification. Under non-stress condition, stress, number detected spots 1,571 ± 117, 1,281 231 904 127, respectively. Four proteins high expression identified: dehydrogenase, cysteine synthase A, aldo/keto reductase ribosomal L7/L12. These are thus potential targets for reconstruction to promote its resistance stress.
