Abstract
Spirulina platensis
is a filamentous cyanobacterium recognized for its high nutritional value and
extensive applications in the food, pharmaceutical, cosmetic, and aquaculture
industries. Due to its rich composition of proteins, vitamins, essential amino
acids, pigments, and antioxidants, large-scale cultivation of Spirulina
has gained considerable commercial importance. The present study was conducted
to evaluate the influence of different culture media on the growth performance
of Spirulina platensis under controlled laboratory conditions. The
organism was cultivated in various nutrient media, and growth was monitored by
measuring optical density at regular intervals. Significant variations in
growth rate were observed among the tested media, indicating that nutrient
composition strongly affects the metabolic activity and nutrient assimilation
efficiency of the cyanobacterium. Among the media tested, certain formulations
supported superior growth due to the availability of balanced macro- and micronutrients
essential for photosynthesis and cellular development. The findings of this
study demonstrate that optimization of culture media is a key factor for
enhancing growth of Spirulina platensis. Furthermore, the study
highlights the potential for developing cost-effective cultivation strategies
for sustainable commercial production and biotechnological applications.
