“…Various species have been cultivated by adding agricultural fertilizers: Gracilaria chilensis [ 40 ], Chondracanthus squarrulosus [ 41 ], Porphyra spp. [ 42 , 43 ], Sarcothalia crispata [ 44 ], Sarcopeltis skottsbergii (formerly Gigartina skottsbergii ) [ 45 , 46 ], and Chondracanthus chamissoi [ 20 , 47 ]. Likewise, the commercial fertilizer Bayfolan ® (Bayer, Lima, Peru) has been widely used in macroalgae cultures, demonstrating good performance [ 20 , 43 , 46 ].…”

Chondracanthus chamissoi is an edible red seaweed with a high hydrocolloid content and food industry demand. This situation has led to a decline in their populations, especially in Peru. An alternative culture method based on the formation of secondary attachment discs (SADs) has shown several advantages over traditional spore strategies. However, there are still scarce reports of the SAD method in Peru. This work aimed to evaluate the best conditions for C. chamissoi maintenance prior to SAD development and the effect of locality on SAD formation using scallop shells as a substratum. Experiments were conducted with material collected from five localities in Pisco (Ica, Peru). Our results showed that the best conditions for C. chamissoi maintenance were: (1) fertilized seawater with Bayfolan® (0.2 mL L−1); and (2) medium exchange every two days or weekly. These conditions reduced the biomass loss to 9.36–11.14%. Most localities showed a similar capacity to produce SADs (7–17 SADs shell−1). However, vegetative algae, especially Mendieta, tended to present a higher number of SADs. Vegetative fronds also showed lower levels of necrosis and deterioration compared to cystocarpic and tetrasporophytic samples. This study shows the technical feasibility of culturing C. chamissoi through SADs for developing repopulation and/or intensive cultivation projects in Peru.

“…There are very few studies about the usage of agricultural fertilizers for macro and microalgae cultures (Ak et al 2011;Raoof et al 2006;Werlinger et al 2009). No literature has been found on the effect of the agricultural organic fertilizers on growth of microalgae.…”

In this study, the influence of an agricultural liquid organic fertilizer on growth and biomass composition of Spirulina platensis Geitler was studied. In the first trial, five concentrations of organic fertilizer were arranged, e.g., 0.1, 0.25, 0.5, 1 and 2 ml/l, in which no other extra nutrients except bicarbonate were used. Maximum dry weight, chlorophyll a and specific growth rate were achieved in control group. In the second trial, initial fertilizer levels of the three groups were 0.1 ml/l and all groups contained sodium bicarbonate. One of the groups had 2.5 g/l NaNO 3 , while the other was supported with 0.1 ml/l fertilizer by two-day intervals to see the effect of nitrogen. In order to understand the effects of phosphate, 0.4 g K 2 HPO 4 was added to the other group as well as 2.5 g NaNO 3 . Between the experimental groups, the highest chlorophyll a value was found in control group as 53.97 mg/l. The chlorophyll value at group II (37.65 mg/l) was lower than the control group. The maximum dry weight and crude protein recorded in control group were 1,330 mg/l and 60.17%, respectively, when compared with 1,256 mg/l and 59.92% in group II. No significant differences were observed in crude protein values of Spirulina grown in control and group II (P \ 0.05). Consequently, it was seen that commercial liquid organic fertilizers may be replaced by Zarrouk's medium except for nitrate, phosphate and bicarbonate in S. platensis cultures in order to decrease the production costs.
