“…In conclusion, although previous studies concerning molecular identification of some algae from other Middle East countries (Attaran-Fariman and Javid, 2013;Attaran-Fariman and Bolch, 2014) are available, to the best of our knowledge, this preliminary study is the first phylogenetic investigation to determine the algal diversity of Anatolian freshwaters and contains the first reports for Chlorella sorokiniana and Heterochlorella luteoviridis species. In addition to these 2 new records, it also contains the first phylogenetically identified true Chlorella vulgaris isolates.…”

IntroductionMany coccoid algae are very difficult to identify because of their extremely small size and simple morphology, and they have been referred to as "little green balls" (Callieri and Stockner, 2002). These little green balls have often been reported as Chlorella Beijerinck or Chlorella vulgaris Beijerinck (Fawley et al., 2004). Since C. vulgaris "Beijerinck strain" (SAG 211-11b) was first described and isolated in axenic culture about 120 years ago, Chlorella strains have been used as model organisms in plant physiology and biochemical research (Burja et al., 2001). Furthermore, mass cultures of Chlorella have been used in agriculture as a single cell protein both for humans and animals, in biotechnology as recovery agents for waste treatment, and in biofuel technology as microbial energy producers (Golueke and Oswald, 1964;Fogg, 1971;Soeder, 1976;Abbott and Cheney, 1982).Among the over 100 traditionally defined Chlorella species, a lack of morphological characters led to the adoption of various approaches, including several combinations of physiological, biochemical, and serological studies, for identifying Chlorella species (John et al., 2003). The morphologically-defined species are considered very artificial and house many cryptic taxa. Using molecular data, Huss et al. (1999) demonstrated that only 5 "true" species could be regarded as part of the genus Chlorella. Materials and methods Chlorella isolationsEnvironmental water samples were taken from the

“…Its length also ranges 30–50 μm, which is similar with other Chattonella species but is shorter than C. antiqua (now C. marina var. antiqua ) which is about 50–130 μm (Imai & Yamaguchi ; Attaran‐Fariman & Bolch ). However, C. subsalsa may be a species complex comprising of an Adriatic Sea and a ‘global’ clade which can be distinguished by the shape of the chloroplasts (Klopper et al .…”

Blooms of the raphidophyte Chattonella subsalsa have been associated with massive fish-kill events in several parts of the world. However, there have been few studies into physiological responses of tropical strains that could contribute to bloom outcomes. Such knowledge could provide insight into the C. subsalsa blooms recently documented within tropical coastal waters (e.g., 2010 and 2012 events in Singapore). Strains used in this study were isolated from the East Johor Straits (EJS), Singapore, an enclosed water channel frequently subjected to high levels of eutrophication. These cells were classified within the 'global' clade (and distinct from the 'Adriatic Sea' clade) based on morphology. The present study examined cellular responses to varying inputs of different forms of nitrogen (N), specifically nitrate, ammonium, and urea. Results from the study indicated that cells were unable to utilize urea as an N-source, but grew well on a nitrate (V max = 0.73 day −1 ) and ammonium (V max = 0.81 day −1 ) supply. These growth rates were high compared to other strains from around the world, indicating that tropical C. subsalsa could exhibit elevated bloom potential within frequently eutrophic environments such as the EJS. Six pigments were detected in all cultures. These pigments were chlorophylls a and c; fucoxanthin; diadinoxanthin; violaxanthin; and β-carotene. Chlorophyll-a and fucoxanthin were the dominant pigments under both nitrate and ammonium regimes. Measurements of chromophoric dissolved organic matter generally increased both in molecular weight and in total content across the N-concentration ranges. Such outcomes could have consequences for the chemical and optical conditions of the coastal environment.
