Biosorption is a promising alternative method to treat industrial effluents, mainly because of its low cost and high metal binding capacity. In this work, Zinc and Chromium biosorption process by Sargassum sp. seaweed biomass was studied. The work considered the determination parameters of Zinc and Chromium sorption such as pH, temperature, agitation speed and biomass size. The optimum conditions were: pH3, temperature (303k) room temperature, biomass size 0.5mm and agitation speed 150rpm. The maximum uptake of Chromium and Zinc is 65% and 53% respectively. The kinetic study revealed that the adsorption of Chromium and zinc by Sargassum sp. fitted the Langmuir isotherm.Keywords

Health promoting microorganisms such as probiotics are recently been used as food additive and therapeutic supplement especially as enhancer of prophylaxis and digestion. Here we report the isolation and characterization of a probiotic bacillus species, with the ability to ferment lactose, from dairy effluent. Biochemical test and 16S rRNA sequencing were done in order to establish the species and strain details. The species was found to be Bacillus subtilis SK09 with a unique ability to ferment lactose. The strain was also subjected to commonly available antibiotics for its antibiotic susceptibility for its probiotic credibility.Keywords
