Detoxification and color removal of Congo red by a novel Dietzia sp. (DTS26) - a microcosm approach.
The present study deals with the decolorization and detoxification of Congo red (CR) by a novel marine bacterium Dietzia sp. (DTS26) isolated from Divar Island, Goa, India. The maximum decolorization of 94.5% (100 mg L(-1)) was observed under static condition within 30 h at pH 8 and temperature 32±2°C. Bacterially treated samples could enhance the light intensity by 38% and the primary producti...
Novel nickel hierarchical structures were prepared through a facile one-pot solvothermal approach in the presence of surfactant and mineralizer. The influence of dynamics factors such as polyvinylpyrrolidone (PVP) content, ratio (R) between NaF and NH(3)·H(2)O on the morphologies of the as-synthesized products were investigated in detail. By regulating the dynamics factors, nickel crystals with...
tungsten trioxide nanoparticles with monoclinic structure and average particle size about 80 nm were prepared by the spray pyrolysis method. wo3 nanorods with hexagonal structure and average dimension about 15 × 100 nm were synthesized in gram quantities by modified hydrothermal method at lower temperature and shorter reaction time in comparison to the previous research. photo degradation of co...
Sections of hyalinized laryngeal polyps stained with haematoxylin and eosin or Congo red can easily be confused with localized amyloid of the larynx. Several histological methods were applied to 61 specimens containing hyaline deposits or hyalinized tissues which included 36 laryngeal polyps. The results were compared with seven cases of localized amyloidosis of the upper respiratory tract and ...
Clinical isolates of the opportunistic pathogen Mycobacterium avium complex (MAC) undergo a reversible switch between red and white colony morphotypes on agar plates containing the lipoprotein stain Congo red. Compared to their isogenic red counterparts, white morphotypic variants are more virulent and more resistant to multiple antibiotics. This report shows that the two-component regulatory s...
It has been claimed that, in patients with amyloidosis, the presence of amyloid material in the skin may be demonstrated by the intracutaneous injection of Congo red (Philpott and Freshman, 1936; Nomland, 1936). In the presence of amyloidosis, the area of staining is said to be more intense and to persist for a longer time than in normal skin. Recently this technique has been employed by Laine,...
This communication reports the use of Congo red to stain the nanofibers of self-assembled small molecules for assaying intracellular supramolecular hydrogels, which provides a convenient method to explore molecular self-assembly inside cells.
BACKGROUND Dialysis-related destructive spondyloarthropathy caused by beta-2 microglobulin (β2M) amyloid deposits in intervertebral discs is a major burden for patients undergoing long-term dialysis. This study aimed to quantify the presence of β2M amyloid deposits in the intervertebral disc tissue of such patients and analyze whether there was a significant correlation between β2M accumulation...
