Abstract. Irawati W, Pinontoan R, Mouretta B, Yuwono T. 2021. The potential of copper-resistant bacteria Acinetobacter sp. strain CN5 in decolorizing dyes. Biodiversitas 23: 680-686. Bacteria with multi-resistance to copper and dyes may be employed bioremediation dye waste more effectively than physical or chemical remediation. This study aims at determining the effect addition various textile ...

The effect of initial Congo Red and Procion concentration on isotherm adsorption thermodynamic study using natural Zn/Fe Pillared bentonite have been conducted. adsorbents were also characterized by Fourier transform infrared (FTIR), X-Ray Diffraction (XRD), Scanning electron microscope-energy dispersive analysis (SEM-EDX). showed that the optimum dye removal was obtained at 80 mg/L. followed F...

Cellulolytic fungi can easily be screened within 2 d for the production of cellulolytic enzymes by staining with Congo red, or by measuring the amount of reducing sugar (glucose) produced with the dinitrosalicyclic acid reagent method. Endoglucanase activity is visible in carboxymethyl cellulose agar plates after staining with Congo red, and fixing with HCI or NaOH. This method is essentially b...

BACKGROUND Detection of amyloid can be done by several techniques either histochemical or immunohistochemical. Among them, one of the less mentioned in texts of reference and in reports on amyloidosis, is the examination with ultraviolet light of the stain of Congo red. We intend to examine cases of amyloidosis stained with Congo red with ultraviolet light and to see if such method offers advan...

Immobilizing of zero-valent iron in mono- and bi-metallic systems on the bentonite clay surface as new nanocatalyst were synthesized and used to degrade model acidic dyes from aqueous media. The Fourier-transform infrared spectroscopy, scanning electron microscopy-energy dispersive X-ray spectroscopy, transmission electron microscopy, X-ray diffraction, and Brunauer-Emmett-Teller analysis were ...

The ring-closing metathesis reaction of dendrimers containing allyl ether end groups is known to rigidify them significantly. Herein we report that polyallylated hyperbranched polyglycerol (HPG) 1 complexes the sodium salt of rose Bengal in chloroform solution but releases it readily to water. In contrast, extensively cross-linking 1 with Grubbs catalyst provides 2 which similarly complexes ros...

introduction: biofilm producing staphylococcus aureus is known as one of the major causative agents of infections, failure of implanted devices and persistent infection among hospitalized patients . the aim of the present study was to determine the frequency of biofilm producing s. aureus isolates amongst the clinical specimens. methods: this cross-sectional study was conducted during 2012 to 2...

carbon activated powdered was prepared from activated carbon derived from olive stone. then byusing the surface methodology, many parameters such as ph, furnace temperature (t), acid ratio,time of activation that affect on the qualities prepared activated carbon produced and its efficiencywere investigated. in addition, the adsorption of congo red onto the activated olive stone carbonactive was...

The permanganate method was applied to tissues from 35 cases of amyloidosis seen at the University Hospital. Kuala Lumpur. This method is based on the difference in affinity of various chemical types of amyloid for Congo red dye after treatment with potassium permanganate. Our findings agree with the concept that amyloid of largely immunoglobulin light chain composition (primary and myeloma amy...
