The physiological and biochemical responses of two green algae Ankistrodesmus falcatus and Chlorella vulgaris to copper sulphate were investigated. In this experiment both Ankistrodesmus and Chlorella cultures were treated with copper sulphate concentrations ranging from 0. 5 to 250 μM. The influence of copper on growth and metabolism was determined. Ankistrodesmus grown at 250 μM copper sulpha...

The knowledge of population effects of food on tropical, filter-feeding cladocerans is scarce because a reduced number of species has been extensively studied. Ceriodaphnia rigaudi Richard 1894, a small-sized cladoceran distributed mainly in tropical and subtropical regions of the world, was studied. The aim of this study was to contribute to the knowledge of the reproductive biology of a poor-...

Longevity is a highly variable life history trait and its variation is attributable to both genetic and environmental factors. Exploring well-known environmental factors in a new model system is a useful approach to explore taxonomic variation in plasticity of longevity. We examined responsiveness of the Daphnia pulex clone TCO to potentially related interventions that have been reported to ext...

Microalgae are characterized by rapid photoautotrophic growth and a high rate of biomass accumulation considered as an alternative feedstock for renewable energy sources such biodiesel. Biofuel research is not just matter finding the right type converting it into fuel, but also environmentally economically viable options. The paper presents results studies on use thermal mineral water medium cu...

Aim: Over dependence on fossil fuels has triggered environmental and economic concerns, creating an ultimate need to redirect towards renewable energy options. Hence, the study biodiesel production from algal biomass.
 Study Design: Modified open pond culture system was applied in biomass growth monitored via pH turbidity.
 Place Duration of Study: done laboratory Department Environme...
