Figure 2From: Functional characterization of a Penicillium chrysogenum mutanase gene induced upon co-cultivation with Bacillus subtilis Change of B. subtilis morphology in chemostat cultures. A: Mixed culture of B. subtilis and P. chrysogenum at 0Â h; B. subtilis cells were pregrown in shake-flask culture and addition to a P. chrysogenum glucose-limited chemostat culture. B: Mixed culture of B. subtilis and P. chrysogenum at 72Â h. C: pure culture of B. subtilis after 72Â h of glucose-limited cultivation. Pictures taken under oil immersion and 1000X magnification using a Zeiss Axio imager D1 and an Axio Camera.Back to article page
