• Rossall [29] described similar results, since the addition of D-glucose but not L-glucose lead to the formation of inhibitory volatiles by Bacillus subtilis. The milder inhibitory potential of X. c. pv. vesicatoria 85-10 growing on NBG, may be explained by the suggestions that (i) inhibitory volatiles

• by PTR–MS [56][57]. Nevertheless in our experiments with X. c. pv. vesicatoria 85-10 we did not detect any significant signal at m/z = 28 corresponding to HCN. Ammonia emissions by X. vesicatoria and of two Bacillus subtilis strains in cocultivation with Neurospora crassa were described [58][59

• different Gram-positive (Micrococcus luteus, Bacillus subtilis, Staphylococcus aureus) and Gram-negative (Escherichia coli, Pseudomonas aeroginosa) bacteria, as well as yeast (Candida albicans, Saccharomyces cerivisiae). However, consistent with the published data [12], no antibacterial or antifungal

• 1, 2, 6, and 7 have not been previously reported. The cytotoxicity of 1–9 against human malignant melanoma A735 and cervical carcinoma HeLa cell lines, and the antibacterial activity of 1–5 and 7 towards bacteria Escherichia coli, Bacillus subtilis and Micrococcus luteus were evaluated. The possible

• by MTT assay. The results show that 1–9 does not exhibit cytotoxicity against A735 and HeLa cell lines with IC50 > 200 μg/mL. Antibacterial activity of compounds 1–5 at a concentration of 25 μg/disc (diameter 6 mm) was measured against bacteria Escherichia coli, Bacillus subtilis, and Micrococcus

Other reaction conditions including enzymatic catalysis (Bacillus subtilis) [13], zinc-active-site acylases from Escherichia coli and Aspergillus oryzae [23] as well as ultrasonic irradiation in the presence of montmorillonite [14] have also been reported. In addition, there has been several recent

Minimum inhibitory concentrations (MIC), the lowest amphiphile concentration at which no viable bacterial cell is present, are presented in Table 1. Both 1 and 2 were found to be effective in

Gram-negative bacteria investigated include Escherichia coli and Klebsiella aerogenes. Investigations of antibacterial activities were performed
