This suggestion is supported by the correlation between reduced microsclerotial and pigment production, and reduced survival of V. dahliae[ 12, 13].
a Effect of different amino acids on red pigment production; and b the pigment yield varied with Tyr dosage.
Such study provides quantitative information about kinetic parameters of pigment production and bacterial growing.
The most active cinnamaldehyde analogs were found to affect the starvation response, biofilm formation, pigment production and protease production in Vibrio spp in vitro, while exhibiting low cytotoxicity.
TT8 regulates seed coat mucilage production, seed coat pigment production and anthocyanin biosynthesis.
A significant result in understanding the Tyrp1 and Gpnmb mediated iris disease is that modulating pigment production with tyrosinase (Tyr, a gene essential for pigment production) and hypopigmentation mutations completely rescues iris atrophy and pigment dispersion [ 22, 23].
Pigment production and growth on tryptic soy agar at 35°C and 42ΕC were observed at 24 and 48 hours.
In our clinical pair of phenotypic variants, pigment production and hemolytic activity was reduced (but not eliminated) in 1 variant.
All isolates were identified as M. tuberculosis by using biochemical tests, including production of niacin, catalase activity, nitrate reduction, pigment production and growth rate [ 15].
Many early studies reporting differences between haemolysin and pigment production relied on qualitative visual detection of haemolysin and pigment, and this may explain the observed discrepancies between pigment and haemolysin to some extent.
