Crystal violet is a triphenylmethane dye which is commonly used in the clothing industry to dye wool, silk and cotton (Kim et al., 2005).While knowledge of the genes and enzymes involved in the biodegradation of this dye is restricted; the mechanistic pathway of its break down is well understood. Yatome and colleagues (1993) were the first to elucidate the degradation of crystal violet by Nocar...

We investigate distributions of crystal violet and malachite green on plasmonic surfaces by principal component analysis (PCA) imaging of surface-enhanced hyper-Raman scattering (SEHRS) data. As a two-photon excited Raman scattering process, SEHRS provides chemical structure information based on molecular vibrations, but follows different selection rules than the normal, one-photon excited surf...

Recent evaluations of the MacConkey agar test for differentiation of rapidly growing mycobacteria have revealed that certain strains of Mycobacterium fortuitum and M. chelonei that were expected to grow on MacConkey agar failed to do so. Investigation of two formulations of MacConkey agar showed that these two species grew better on the medium when the crystal violet dye was omitted. Several po...

We have used resonant soft x-ray scattering to study the effects of discommensuration on the hole Wigner crystal (HC) in the spin ladder Sr(14-x)CaxCu24O41 (SCCO). As the hole density is varied the HC forms only with the commensurate wave vectors L(L) = 1/5 and L(L) = 1/3; for incommensurate values it "melts." A simple scaling between L(L) and temperature is observed, tau1/3/tau1/5 = 5/3, indic...

objective(s):bacterial biofilm has been considered responsible for many deaths and high health costs worldwide. their better protection against antibacterial agents compared to free living cells leads to poor treatment efficiency. nanotechnology is promising approach to combat biofilm infections. the aim of the present study was to eradicate staphylococcus epidermidis biofilm with silver nanopa...

Green-fluorescent intracellular enteropathogenic bacteria were observed after infected HeLa cell monolayers were stained with acridine orange and counterstained with crystal violet at least 3 h after infection.
