The inorganic (5 ppm PO4-P and 50ppm NO3-N) and organic (30Ml day 1 milk whey) nutrients were examined on degradation of Methyl Red (MR) at different hydraulic retention time under aerobic and anaerobic conditions in two different bioreactors; one having only gravel soli matrix while the other having 75% gravel and 25 % coarse river sand solid matrix. The physico-chemical properties of the bio...

A solution to the problem of eliminating the use of toxic reagents in the laboratories of the South African sugar industry has been sought for some time. This paper contains the results of an investigation to replace basic lead acetate as a clarification agent in the determination of pol by substituting it with a mixture of aluminium chloride and calcium hydroxide. This mixture achieves good cl...

Pteris vittata L., a fern was evaluated for its alpha amylase inhibitory potential owing to its previously reported antihyperglycemic activity. This Pteridophyte was also assayed for its free radical inhibition ability in ABTS decolourisation assay followed by quantification and HPTLC of polyphenols. The Porcine pancreatic alpha amylase inhibition was studied invitro and compared with standard ...

The low cost adsorbents namely Rice Husk Carbon (RHC), Wheat Straw Carbon (WSC) and Saw Dust Carbon (SDC) have been tested for the effectiveness in decolourisation of wastewater containing a mixture of dyes. Three dyes namely crystal violet, direct orange and magenta have been used for imparting colour in the representative samples of wastewater. Effect of various parameters such as agitation t...

Following previous tests done on chemically regenerable carbon, Norit has developed a new grade of carbon that has faster adsorption kinetics. The effect of repeated cycles and chemical regenerations on the colour removal performance of this carbon has been investigated. Decolourisation trials were performed on brown liquor with a pilot plant supplied by Norit at the SMRI. Tests were carried ou...

In this paper, the effect of NaCl and Na2SO4 on the biodecolourization of reactive brilliant red K-2BP by a Halomonas sp. GYW (EF188281) was investigated in details. The decolourisation efficiency and the oxidation-reduction potential (ORP) change were explored during the decolourization process. The results from sequencing batch tests showed that Na2SO4 influenced the decolourization efficienc...

In the present study, Chryseobacterium geocarposphaerae DD3 isolated from textile industry dye effluent in West Bengal, India, displayed significant tolerance to sulfonated di-azo Congo red (CR), up 500 ppm. The optimum decolourisation revealed that C. was capable of 96.52% 0.2 g L−1 CR within 12 h treatment presence 5 glucose as supplementary carbon source. Biodegradation analysis decolourised...
