Fig. 1From: Rapid optimization of spore production from Bacillus amyloliquefaciens in submerged cultures based on dipicolinic acid fluorimetry assayCalibration curves of spore counts of B. amyloliquefaciens BS-20 and their fluorescence intensity. The spores of B. amyloliquefaciens BS-20 with 1.34 × 108 CFU/mL were twofold serially diluted and treated for the detection of fluorescence intensityBack to article page
