Removal of Dyes by Biosorption on Biomass Ash
Rattan, V.K.,Singh, Harminder,Purai, Abhiti Korean Carbon Society 2007 Carbon Letters Vol.8 No.1
The use of low cost and ecofriendly adsorbent has been investigated as an alternative to the current expensive method of removing dyes from wastewater. Cow dung cakes were collected from the nearby village which was burnt in a muffle furnace at $500^{\circ}C$ to obtain the required ash. This paper deals with the removal of Reactive Blue 221, Acidoll Yellow 2GNL and Olive BGL which are mainly used in textile industry, from aqueous solution by cow dung ash without any pretreatment. The adsorption was achieved under different pH, adsorbate concentration and the applicability of Langmuir and Freundlich isotherms were examined.

The ability of cow dung ash without any pretreatment to remove color from textile dyes N Blue RGB, Green B and EOSIN YWS from aqueous solution has been investigated in this work. Cow dung ash, an ecofriendly and low cost adsorbent was prepared by burning cow dung cakes in the muffle furnace at $500^{\circ}C$. The adsorption was achieved under different pH and adsorbate concentration. The data was fitted to simple polynomial and the isotherms similar to Langmuir and Freundlich isotherms.

Cotesia are larval endoparasitoids and are potential biocontrol agents for various insect pests. In the present study, we attempted to detect the allele-specific ftsZ gene of Wolbachia in Cotesia spp. obtained from different geographical locations. Samples of Cotesia plutellae originating from India (Bangalore and Ludhiana), Kenya,and South Africa and samples of C. glomerata from India (Solan) confirmed the presence of Wolbachia. However, C. plutellae samples from the Kullu region of India did not show infection with Wolbachia. ftsZ sequences showed a high degree of homology within the species (N99%). The low genetic distance in the infected Cotesia populations indicated a single ancestral type, and distance to and from the outgroup suggested that populations are from the same species. Phylogenetic grouping of Cotesia species on the basis of geographic origin showed that the Wolbachia strain is closely related to strains that infect phylogenetically distant hosts.
