Effect of textile dyes on Spirulina platensis

Abstract

Textile effluents are the basic problem to pull down the level of nutrient source of water and that source is spirulina , it is well known as it also create a film on water surface so that due to lack of sunlight aquatic life suffers. Here effect of many dyes have been observed by using proper methods, and it is concluded that on increasing the concentration of dyes in water then it resist the growth of spirulina platensis and decrease its nutrient level as well. In this paper three textile dyes have been taken congo red, metanil yellow and mordant green, results have been noticed as, on 14th day in control 0.435 absorbance has been found while at 100mg concentration, 0.397 absorbance has been found in congo red, 0.210 has been found in metanil yellow and 0.210 in mordant green. These results depict that the above statement is true. This paper also shows the effect of these dyes on chlorophyll content, carbohydrate content and protein content, in control on 14th day the chlorophyll content noticed as 0.369 on the other hand congo red at 100mg concentration read 0.242, metanil yellow as 0.136 and mordant green is taken as 0.216.
