Microbiological assessment and some physico-chemical properties of water sources in Akungba-Akoko, Nigeria

A comparative study was carried out to determine the quality of three water sources: borehole, well and stream in Akungba-Akoko, Ondo State. The water sources were assessed for microbiological quality and physico-chemical properties (temperature, odor, color and pH). The stream had the highest plate count of 40 × 105 cfu/ml, while those of borehole and well water had the least of 12 × 105 cfu/ml...

Ribosomal protein S3 gene expression of Chironomus riparius under cadmium, copper and lead stress

Heavy metals are of interest because they are often present at significant levels in the environment and can have severe effects on the aquatic environment. To examine the effects of oxidative stress induced by heavy metals on chironomids, the full-length cDNA of ribosomal protein S3 (RpS3) from Chironomus riparius was determined using molecular cloning. The basal expression of the RpS3 gene was not affected...
