In this study, the pigment production of Vibrio sp. was studied under different physicochemical conditions. There was no pigment production at high or low temperatures, high or low salt concentrations in peptone yeast extract (PYE) medium, low glucose concentration in mineral growth medium or high glucose concentration in PYE medium. This indicates that the red pigment production is a luxurious good that Vibrio sp. makes only under favorable conditions. The red pigment is also a redundant antibacterial agent of Vibrio sp.

The paper examines the in?uence of various factors on S. cerevisiae invasive growth quantitatively. Assays, used until now, limit the feasibility and interpretation of analyses and needed to be improved. A quantitative agar-invasion assay, presented in our previous work, was applied to clarify the signi?cance of the stress factors controlling the adhesion and invasion of the yeast. Ten virulent and non-virulent strains were assayed at various factors. With the use of speci?c parameters eight invasive growth models were hypothesized, which enabled intelligible interpretation of the results.
