Isochrysis galbana is a unicellular microalga belonging to the kingdom Protista, division Haptophyta, and class Prymnesiophyceae. It is a widely studied species in the field of marine biology due to its important role in marine food webs and biogeochemical cycles. The genus Isochrysis is known for its high lipid content, making it a promising candidate for the production of biofuels and other bioproducts.

Isochrysis galbana culture is commonly used in educational settings to demonstrate the principles of algal culturing and photosynthesis. It is also used as a feed source for a variety of marine organisms in hobby aquaria, as well as for commercial aquaculture operations.

In addition to its applications in education and hobby aquaria, Isochrysis is also used in industrial biotechnology applications such as biofuel production, bioremediation, and bioplastic production.

Isochrysis has a long history of use in academic research, particularly in the study of marine phytoplankton ecology and physiology. Its small size and high growth rates make it a useful model organism for studying algal physiology and biochemistry.

To culture Isochrysis galbana, it is typically grown in a seawater-based medium such as F/2 , at a pH of 7.5-8.5 and under moderate to high light intensity. The culture can be maintained at temperatures of 15-25°C. Growth rates can vary depending on the specific strain of Isochrysis galbana and the conditions of the culture, but can range from 0.5 to 1.5 divisions per day.
