Effect Nutrients for Growth Chlorella Vulgaris and Spirulina Platensis

Microalgae are versatile organisms with the ability to adapt to various environments and exhibit rapid growth. They play a significant role in photosynthesis by converting carbon dioxide into oxygen and utilizing nutrients in their surroundings. This study aims to investigate the impact of nutrient availability on the growth of Chlorella vulgaris and Spirulina platensis. The experiment involves culturing the microalgae in mineral water and distilled water mediums supplemented with Walne medium nutrients. The growth of microalgae is monitored daily by calculating cell density using a counting chamber method. The pH and temperature of the culture are also measured. The results show that both microalgae species can grow in both mediums, but the usagee of mineral water medium promotes higher cell density and growth rates compared to distilled water medium. The pH values of the cultures vary between mediums, with mineral water medium generally exhibiting higher of pH. The temperature remains relatively stable throughout the experiment. These findings indicate that nutrient availability has a significant influence on microalgae growth, and the use of mineral water medium enhances their growth potential.
