Fig. 5From: Study on the mechanism of efficient extracellular expression of toxic streptomyces phospholipase D in Brevibacillus choshinensis under Mg2+ stressSDS-PAGE analysis of PLD expression. It was harvested at 48Â h. Lane 4: protein marker; lanes 1,7: intracellular and extracellular protein of B. choshinensis/pNCMO2-PLD cultured in medium A without Mg2+; lanes 2,6: intracellular and extracellular protein of B. choshinensis/pNCMO2-PLD cultured in medium A; lanes 3,5: intracellular and extracellular protein of B. choshinensis cultured in medium ABack to article page
