ABSTRACT. Cultivation of cyanobacterium Arthrospira sp. has been developed in many countries for the production of proteins, pigments and other compounds. Outdoor mass cultures are often affected by biological contamination, drastically reducing productivity as far as bringing death. This study evaluates the control of Branchionus sp. and Amoeba sp. with two chemical compounds: urea (U) and ammonium bicarbonate (AB), in laboratory conditions and outdoor mass culture of Arthrospira sp. The lethal concentration 100 (LC100) at 24 h for Branchionus sp. and Amoeba sp. determined was of 60-80 mg L -1 (U) and 100-150 mg L -1 (AB). The average effective inhibition concentration for 50% of the population (IC50) in Arthrospira sp., after 72 h, was 80 mg L -1 (U) and 150 mg L -1 (AB). The application of doses of 60 mg L -1 (U) or 100 mg L -1 (AB) in the outdoor mass culture of this contaminated microalga, completely inhibited grazing and did not affect the growth of Arthrospira sp. but rather promoted rapid recovery of algal density at levels prior to infestation. These compounds provided an economical and effective control of predators in cultures of Arthrospira sp.

“…For example, lipids and pigments have been produced from glycerol by cyanobacterium Spirulina platensis (Narayan et al 2005). Docosahexaenoic acid (DHA) and other lipids were generated from a marine microalga, Schizochytrium limacinum SR21 grown on glycerol (Pyle et al 2008).…”

Biomass and lipid productivities of Chlorella vulgaris under autotrophic, heterotrophic and mixotrophic growth conditions

Biomass and lipid productivities of Chlorella vulgaris under different growth conditions were investigated. While autotrophic growth did provide higher cellular lipid content (38%), the lipid productivity was much lower compared with those from heterotrophic growth with acetate, glucose, or glycerol. Optimal cell growth (2 g l(-1)) and lipid productivity (54 mg l(-1) day(-1)) were attained using glucose at 1% (w/v) whereas higher concentrations were inhibitory. Growth of C. vulgaris on glycerol had a similar dose effects as those from glucose. Overall, C. vulgaris is mixotrophic.

“…It was reported that biomass productivity in C. protothecoides was increased when glycerol was used as carbon source [38]. When glycerol was used for cyanobacterium Spirulina platensis, lipids and pigments production was increased [24]. Similarly, when marine microalga Schizochytrium limacinum SR21 was grown on glycerol, docosahexaenoic acid (DHA) and other lipids were produced [27].…”

This study investigated the potential use of various organic carbon sources (glucose, glycerol and acetate) and different concentrations of CO 2 for culturing marine microalga Dunaliella tertiolecta. Cell growth and lipid production were monitored under heterotrophic, mixotrophic and photoautotrophic modes of cultivation. D. tertiolecta showed the ability to grow under mixotrophic (acetate and glucose), heterotrophic (glucose) and photoautotrophic condition under high CO 2 concentration (15%). With all the organic carbon sources (glucose, glycerol and acetate) tested in this study, 1~5% acetate enhanced cell growth rate and lipid content, while higher concentrations of acetate (10% and 15%) were inhibitory and resulted in cell death.
