“…These wastes were made into a cabbage extract medium that promoted growth of the microalgae after 15 days, with the highest concentration (10 g L −1 ) producing maximum spirulina biomass of 550 g L −1 (Akhtar et al . 2014). The extracts were an excellent source of vitamins, amino acids and other nutrients, especially because NaCl, NaHCO 3 and urea were added.…”

“…The anti‐bacterial properties of the spirulina culture in different media were also assessed by Akhtar et al . (2014) and reported that only freeze‐dried S. platensis powder extracts exhibited anti‐bacterial potency against Streptococcus pneumoniae , Bacillus subtilis , Shigella dysenteriae and Sarcina lutea . Cabbage skin extracts medium was also compared to the Zarrouk’s medium as control and Bangladesh medium 1 (BD1).…”

The nutritional value of spirulina in aquafeeds has been studied extensively as a fishmeal replacer or as a functional feed additive to increase growth and health performance of fish in the last decade. Despite increased interest in spirulina research in aquaculture, its increased production cost still limits its use in commercial rations. Zarrouk’s medium is the standard substrate used for growing spirulina. Although this medium offers optimal biomass production, it incurs higher costs due to the expensive components needed for concocting the medium. In this regard, development of cost‐effective alternative culture medium or techniques is necessary for the industrial‐scale production of these microalgae. This paper reviews research on different alternative media for spirulina cultivation and its nutritive value as an aquafeed. Numerous alterations in the composition of Zarrouk’s medium with cheaper chemical ingredients have been explored as a potential substitute for cost‐effective microalgae cultivation. Industrial and processing wastes and by‐products with appropriate nutrient profiles for growing spirulina are also being considered as alternative culture media. The use of rice bran or other cheaper agricultural by‐products, as a cost‐effective growth medium for commercial‐scale spirulina production has yet to be explored extensively in agriculture‐based countries, especially in rice‐producing Asian countries.
