Spirulina (Arthrospira) platensis biomass has a wide range of applications in several industries. One of the key issues for its production is the reduction of the culture medium cost. Here we have shown the possibility of a single recycling (repeated usage) of the modified Zarrouk nutrient medium (MZM; which contains 8.4 g/l of NaHCO 3 and 0.1 g/l of NaOH instead of 16.8 g/l of NaHCO 3 ) for spirulina cultivation without altering culture productivity, photosynthetic pigments and protein contents in its biomass given that technological approach consisting in application of a mixture of a freshly prepared and once recycled modified Zarrouk medium in a ratio of 1:1 by volume is used. The obtained results can be applied for further reduction of costs of spirulina biomass production compared to methods described in previous studies.
