Responses of blue-green and green algae to streptomycin in unialgal and paired culture

Streptomycin affects the growth and photochemical activity of the alga Chlorella vulgaris

“…It has been observed that Chlorella vulgaris is capable of growth at concentrations up to 21 mg L À 1 of streptomycin (Harrass et al, 1985), however this is a much higher concentration than that used in this study, which indicates that: 1) the effect of the antibiotic is species-specific and 2) growth conditions may change the effect of the antibiotic. Furthermore, Pramer (1956), reported that the presence of ethylenediaminetetraacetic acid (EDTA) lowers the cellular uptake of streptomycin, which decreases its effect on the growth in Euglena sp.…”

Allelopathic effects of submerged macrophytes on phytoplankton

“…M. aeruginosa was shown to allelopathically inhibit the growth of Chlorella pyrenoidosa by linoleic and linolenic acids (Ikawa et al, 1996) and the freshwater dinoflagellate Peridinium gatunense (Sukenik et al, 2002). Also Harrass et al (1985) and Gregor et al (2008) When tested without interaction (100%), particle-, biovolume-, and chl a-based growth rates of M. aeruginosa were not affected or even slightly enhanced (chl a) by TA in exp. 1, whereas D. armatus was significantly inhibited by TA additions in all parameters.…”

Analyses of gene expression and physiological changes in Microcystis aeruginosa reveal the phytotoxicities of three environmental pollutants

“…It was previously reported that cyanobacteria are more sensitive to some pollutants than eukaryotic algae (Halling-Sørensen et al 1998;Holten Lützhøft et al 1999). For example, some references showed that Microcystis aeruginosa (prokaryote) was more sensitive than Selenastrum capricornutum or Chlorella vulgaris (eukaryote) to streptomycin (Harrass et al 1985;Qian et al 2010). Perrona and Juneau (2011) demonstrated that M. aeruginosa was more sensitive than green algae to endocrine disrupters.…”
