An experiment on the effect of populations of ankistrodesmus and chorella on the growth in the numbe

Phytoplanktonic community In the present study, qualitative analysis of the phytoplankton community in both treatments confirmed the presence of microalgae typical of environments with high content of organic materials and a greater diversity for the aerated in comparisom with the non-aerated treatment.

An experiment on the effect of populations of ankistrodesmus and chorella on the growth in the numbe

Porto Alegre, Brasil. The initial lag phase observed just for the aerated treatment also was found by Bernal et al. Wat Sci Technol — This general classification method was only used to distinguish isolates on the most basic level. The cultures were continuously aerated using air pumps with air stones, and the specified media was added to each culture at the end of every week. Cambridge University Press, Cambridge, pp — Palaeont Electr One milliliter of the diluted sample was transferred to a media plate and spread evenly across the surface. Therefore, location is a key determining factor for the selection of microalgae strains that can be used to produce biomass. Stuttgart, pp.

Wat Air Soil Pol — Toxicol Environ Chem — This fact, alied to algae growth that consumes nitrate and inorganic carbon, can be responsible for the pH maintenance Reynolds, Algae represent a very diverse and heterogeneous complex of organisms belonging to many different phyla, and characterized by very different physiological attributes.

The BG medium was prepared from the modified BG medium recipe[ 212223 ] by removing all forms of nitrogen from the mixture in order to support only heterocystous cyanobacteria. The class Cyanophyceae was detected from the 5th to the 15th day in the non-aerated bioassays.

The field samples were first diluted to aid in the isolation process.

Chlorella habitat

Temperature, light intensity, amount and type of nutrients, amount of CO2, and pH are the key factors influencing algal growth. Nutrient media A number of different nutrient media recipes were utilized to isolate the maximum number of colonies from each field sample. Lipid content and biodiesel characterization The algae isolates showing high growth rates were selected for the determination of lipid content. Lipid content was determined for selected strains that demonstrated relatively quick growth. Ap Bioch Biotech — Farina , studying the population dynamics of microalgae in secondary effluent from domestic aerobic treatment, found dominance of Cyanophyceae and greater variety of phytoplankton groups than observed in the present research.
