“…It contains high quality protein, which range between 50 and 70% of its dry weight (Falquet 1997;Hosseini et al 2013), essential amino acids and fatty acids, vitamins, and dietary minerals (Belay 2008;Sharoba 2014;Gutiérrez-Salmeán et al 2015). Furthermore, the biomass is very rich in antioxidants such as phenolics, flavonoids, vitamin E, and various light absorbing pigments (e.g., phycocyanin, chlorophylls and carotenoids), which are also essential in preventing the body against free radicals (Kumar et al 2005;El-Baky et al 2008;Chu et al 2010;Michael et al 2018). Due to the exceptional nutritive profile, spirulina has received much attention, and is cultivated massively in health-food industries to serve as food for human, animals, feed additive and pharmaceutical products (Kumar et al 2005;Habib et al 2008;Chu et al 2010;Chen 2011).…”

Introduction Cultivation of spirulina at commercial-scales relies on analytical grade–based media, which are expensive and so are the product. Purpose This study assessed the biomass, proximate composition, and other useful compounds in Spirulina (Arthrospira fusiformis) produced with a cost-effective culture medium (LCMA), and the results were compared with those from a standard Zarrouk medium–grown spirulina. Methods The LCMA medium was formulated by using a commercial NPK10-20-20 fertilizer as a source of the three major nutrients for spirulina growth, and other three ingredients from Zarrouk medium. The experiment was conducted for 28 days in the glass aquaria under indoor conditions. Standard analytical methods were applied for the determination of proximate composition, chlorophyll, minerals, and vitamins in the spirulina biomass. Result The LCMA medium showed the best growth conditions by accumulating higher chlorophyll content (0.99 ± 0.02%) and dry weight (0.75 ± 0.01 g/100 ml) as well as attaining higher optical density (2.06 at day 15) earlier than the Zarrouk medium. The results of the proximate analysis for spirulina cultured in the LCMA medium were of good quality, with the protein contributing more than 50% of its dry matter. It was further noticed that the LCMA was an ideal medium for optimization of vitamins and some minerals since it recorded a significant amount of most of the analyzed vitamins together with the minerals sodium and potassium compared with the Zarrouk medium. Conclusion It is suggested that LCMA medium could be used as the alternative and cheap medium for maximization of biomass and production of useful biochemical compounds in spirulina species.

“…Michael et al . (2018) reported that S. platensis ethanol extract showed a strong chelating power compared with the synthetic metal chelator. The higher metal chelating activity of S. platensis or other marine algal extract is generally due to carboxylic and amino groups from acidic and alkaline amino acids which has responsibility for iron and copper ions adsorption (Akbarbaglu et al ., 2023).…”

“…It might be due to the higher iron chelating activity of basil leaves in ethanol extract compared with water extract (Yes ¸iloglu & S ¸it, 2012). It indicated that basil leaves gave different impacts on the antioxidant activity of both water and ethanol extracts of S. platensis Michael et al (2018). reported that S. platensis ethanol extract showed a strong chelating power compared with the synthetic metal chelator.…”

SummarySpirulina platensis has been known as a super food with a high nutrition and biological activity. The limited addition of S. platensis into the food is due to its unpleasant odour. S. platensis was soaked in basil (Ocimum basilicum) leaves extract (BLE) to decrease the unpleasant odour and its antioxidant activities after soaking were unknown. This study aimed to evaluate the effect of ratio S. platensis with BLE on colour and sensory characteristics and to determine the total phenolic content (TPC) and antioxidant capacity of extracted S. platensis without and with BLE using different solvents. Spirulina platensis was soaked in BLE at a ratio of S. platensis and BLE of 1:3, 1:4, and 1:5 (w/v) for 15 min and then dried at 40°C for 10 h. The resultant powder was analysed for colour and sensory characteristics. The selected S. platensis with the best sensory characteristic was further extracted in water and ethanol and was compared with the S. platensis control (unsoaked in BLE). The ratio of S. platensis and BLE had a significant effect on the colour characteristics (P < 0.05). Spirulina platensis soaked in BLE at a ratio 1:4 had higher L* (35.98), a* (−6.57) and b* values (5.95) than the control. The ratio of S. platensis and BLE at 1:4 had a higher overall sensory value (4.16) than the control (2.35). The water extract of S. platensis unsoaked and soaked in BLE showed a higher TPC (1.178 and 1.667 mg GAE g−1 extract, respectively), DPPH, ABTS and metal chelating, but lower in FRAP compared with the ethanol extract. Spirulina platensis soaked in BLE which were extracted in water and ethanol had higher ORAC (63.27 and 56.33 mmol Teq g−1 extract, respectively) than the control. Spirulina platensis soaked in BLE increased its sensory value while maintaining the antioxidant capacity. Therefore, it can potentially be added in more quantities to various foods as functional foods.

North Sumatera is one of the provinces in Indonesia with the highest buffalo population, which is responsible for the high accumulation of buffalo manure that can cause environmental and aesthetic problems if left untreated. One of the possible alternatives for solving this issue is by implementing buffalo manure as growth media for microorganisms, e.g. microalgae. In this research, buffalo manure was used as alternative media for Arthospira platensis cultivation. Buffalo manure was taken from Sitoluama village, Laguboti, Toba Regency of North Sumatra Province. Research steps included media and culture preparation, cultivation, sampling, sample analysis and verification of constructed models and validation. Buffalo manure concentration in media is varied from 1 g.L-1 to 8 g.L-1 which is analogous to nitrogen content of 0.002 mg.L-1 to 0.018 mg.L-1. Growth data was used for growth kinetic modelling, which was most satisfactory for Monod model (µmax = 0.5915 day-1, Ks = 0.421 g.L-1).
