The mass cultivation of Spirulina platensis in Brazil

A New Algivorous Heterolobosean Amoeba, Euplaesiobystra perlucida sp. nov. (Tetramitia, Discoba), Isolated from Pilot-Scale Cultures of Phaeodactylum tricornutum

“…According to the amoeba contaminations that were described, if an invasion was not controlled quickly, cultures would perish within days ( 30 ). Spirulina platensis cultures grown at an industrial scale of 500 to 2,000 m 2 in Brazil occasionally became suddenly contaminated with unknown amoebae ( 31 ). If the invasion was not dealt with early enough, the amoebae could destroy the culture within 3 days ( 31 , 32 ).…”

“… Spirulina platensis cultures grown at an industrial scale of 500 to 2,000 m 2 in Brazil occasionally became suddenly contaminated with unknown amoebae ( 31 ). If the invasion was not dealt with early enough, the amoebae could destroy the culture within 3 days ( 31 , 32 ). All these studies suggest that algivorous amoebae play a critical role in the demise of microalgal mass cultures.…”

Control of Branchionus sp. and Amoeba sp. in cultures of Arthrospira sp.

“…These organisms generate stress, cellular breaking, detriment and death of the culture. Described contaminations by amoebae suggest that cultures die within days if invasion is not treated quickly (Wagener & de Luca, 1987;Duerr et al, 1997). Rotifers have always been seen as very useful organisms in aquaculture as live food (Planas & Cunha, 1999), however these organisms can cause significant biological contamination in algal cultures (Oswald, 1980).…”
