the aim of this study was to investigate the congo red sorption on soil from the region of iasi (ne of romania). the effects of contact time, temperature, sorbent dose and initial dye concentration on soi sorption were investigated. the results show that the amount adsorbed of congo red on soil increase with increasing dye concentration, temperature and contact time. the experimental data were ...

In this work, the ability of the MgCaFe- Layered double hydroxide (LDH) for congo red (CR) dye removal in aqueous solution was investigated. Various parameters such as initial dye concentrations, temperature, adsorbent dosage, pH effect and agitation rate were examined and optimal conditions (10 mgL-1 of the dye concentration, 25 °C of temperature, 0.5 gL-1 of the adsorbent dosage, pH~7 and 450...

To determine the optimal media conditions for the detection of the extracellular cellulase activity in Ganoderma neo-japonicum, we varied three media conditions: dye reagent, pH, and temperature. We evaluated the use of four dyes, Congo red, phenol red, remazol brilliant blue, and trypan blue. To observe the effect of pH on the chromogenic reaction, we tested media ranging from 4.5 to 8.0. To r...

Introduction The utilisation of food additives becomes more and more important. The red seaweed hydrocolloids agar-agar, carrageenan and furcelleran which are the cell wall polysaccharides and construct differently with a variable amount linked groups are used as a food additive. Red algae belong to the class Rhodophyceae. Agar-agar or short agar, carrageenan and furcelleran are part of the emu...

Amyloidosis represents a heterogenous group of diseases that have in common the deposition of fibrils composed of proteins of beta-pleated sheet structure, a structure which can be specifically identified by histochemistry using the Congo red or similar stains. Amyloid consists primarily of the amyloid fibrils but also of the amyloid P component (AP). This component, which is identical with the...

In a case suspected clinically of having amyloidosis because of the presence of a chronic infection, large liver and spleen, and moderate albuminuria, a Congo Red test done by the current standard method (1) proved to be negative according to present interpretation (60 per cent of the dye was removed from the blood at the end of 60 minutes). A moderate amount of amyloid was, however, shown to b...

To determine the optimal medium conditions for the detection of the cellulolytic activity in Ganoderma lucidum, we varied three media conditions: dye reagent, pH, and temperature. First, we evaluated the use of four dyes, Congo Red, Phenol Red, Remazol Brilliant Blue, and Trypan Blue. To observe the effect of pH on the chromogenic reaction, we also made and tested various media spanning acidic ...

To understand the ability of producing cellulolytic enzyme activity in the sapstaining fungi, four species of Ophiostoma and two species of Leptographium were investigated in the culture media containing each of cellulose substrates such as CM-cellulose, Avicel and D-cellobiose and each of chromogenic dyes such as Congo-Red, Phenol Red, Remazol Brilliant Blue and Tryphan Blue. When the fungi we...

Bu çalışmada geleneksel fermente Türk sucuklarından izole edilmiş toplam 50 adet koagulaz-negatif Staphylococcus (KNS) ve 10 Macrococcus caseolyticus suşlarının biyofilm oluşturma özellikleri fenotipik olarak belirlenmiş aynı zamanda suşlarda oluşumu ile ilişkili genler adezyon genlerinin varlığı multipleks polimeraz zincir reaksiyonu (mPZR) araştırılmıştır. Fenotipik slaym (slime) üretimi Cong...
