Moreover, examining the antimicrobial activity of the
bioactive extractions against common microbial indicators
(Escherichia coli, Bacillus subtilis, Pseudomonas fluorescens,
and Saccharomyces cerevisiae) it was shown that the agar
extract from S. rochei (ACTA1551) was able to inhibit growth
of all the examined indicator microorganisms (Figure 4(b)).
Therefore the antifungal activity of the selected streptomycete
has a wider antimicrobial activity.
