“…In accordance with our results, Chlorella sp. can accumulate a high content of lipids under high N:P ratios of 55:1 and 110:1 (P limitations) compared to the lower N:P ratios of 11:1 and 7:1 (N limitations) (Liang et al 2013). A few algal species, including Chlorella spp.…”

“…A few algal species, including Chlorella spp. (Reitan et al 1994;Liang et al 2013), Dunaliella spp. (Gordillo et al 1998;Takagi et al 2006), Parietochloris incisa (Bigogno et al 2002), Neochloris oleoabundans (Tornabene et al 1983) and Botryococcus braunii (Li and Qin 2005), have also been reported to have the capacity of accumulating large quantities of lipids in cells at high N:P ratios.…”

“…Many studies on nutrient limitation have emphasised the capacity of total lipid change through nutrient manipulation (Liang et al 2013;Sharma et al 2012;Reitan et al 1994), but little research has focused specifically on the changes of PUFA and elemental contents of algae under different N:P ratios. N: P ratios have been manipulated to simulate situations from nitrogen deficiency to phosphorus deficiency as reported in other studies (Hessen et al 2002;Breteler et al 2005;Rodolfi et al 2009) on a variety of green and golden algae species.…”

Microalgae Pseudopediastrum boryanum (Turpin) E. Hegewald was chosen as a subject for the present research due to its potential uses of wastewater treatment and biodiesel production. In the present study, we investigated the growth and biomass production of P. boryanum through use of semi-continuous cultures employing two growth media (Allen and BG-11). In our previous study, P. boryanum was isolated from different freshwater reservoir through the dilution technique. The isolated P. boryanum strain was inoculated with 270 mL of medium + 30 mL of suspension culture and the 16:8 light/dark photoperiod was applied. Optical density was recorded by using UV-Visible spectrophotometer at 670 nm, and cell count examination was performed through drop count method. Besides, dry weight and chlorophyll-a concentration of strain were determined. The highest cell density (3.67x10 6 cells/mL), dry weight (0.032 g/mL) and chlorophyll-a (16.39 µgL -1 ) production were observed in the Allen medium. Growth rates of P. boryanum were found to be 0.6676 d -1 in the Allen and 0.6021 d -1 in the BG-11 medium.Keywords: Pseudopediastrum boryanum, optical density, cell density, growth parameters, culture conditions.

“…Phosphorus is another significant nutrient and necessary for many phosphorylation-dependent events such as ATP (Adenosine Triphosphate) synthesis and the Calvin cycle. Therefore, the lack of phosphorus affects not only the synthesis of chlorophyll but also the growth and metabolism of cells [32,33]. The KH 2 PO 4 in Chlorella nutrient medium and K 2 HPO 4 in Prat nutrient medium is the source of phosphate for algal growth.…”

Chlorella vulgaris is a single-cell, spherical green algae and one of the microalgae on which many applied studies are conducted. In the present study, five strains displaying fast and efficient reproduction were chosen among 11 C. vulgaris strains isolated from different fresh water ponds and their cell numbers and the amount of chlorophyll a, protein, lipid, cellulose and carbohydrate were examined. The main goal of the study is to investigate increasing the biochemical contents especially the protein content of C. vulgaris strains in different mediums. In the present study, cell densities were determined through cell count for five days. In parallel with cell count, their chlorophyll a content was determined. The highest cell density was observed with C. vulgaris TOH (Tourism and Hotel Management Pond) strain as 5.5 × 10 4 h/mL, and the chlorophyll a content as 4.3 × 10 2 mg/m 3 . The highest intracellular protein amount was determined with C. vulgaris GUH (Gazi University Rectorship Pond) (0.061 g/100 mL) and the highest lipid amount was attained with C. vulgaris UIK (Ulus Construction Well) strain as 0.019 g/100 mL. The process of increasing the intracellular protein amount in C. vulgaris GUH strain was carried out in Prat, Yagojinski and Chlorella medium. The results indicated that Chlorella medium increased the intracellular protein amount.
