I'm currently interested in ordering nannochloropsis algae powder for a research experiment and would appreciate some detailed information. Specifically, could you provide the cell concentration at the time of harvest? Additionally, it would be helpful to know whether the algae was harvested during the exponential or stationary growth phase, as this could significantly impact my experimental results. Moreover, I noticed that the product description mentions the presence of six different species within the powder. Could you please list those species? Understanding their characteristics and potential variations will be crucial for my study. Looking forward to your detailed response, as this information will help determine the suitability of your product for my research needs.
