Dear Srinuanpan,
It is very interesting to read your article on "Harvesting of microalgae by pellet forming fungi Trichoderma". Just to get more clarification, i do have few clarifications
1. Is it co-culturing from the beginning or added at specific growth stage of algae.
2. Does it affect the growth of algae or alter the biomass and lipid profile
3. How long it takes to pellet the algae?
4. Is it possible to separate the algal and Trichoderma after pellet formation? in case one want use algal lipids for specific applications.
I am interested to test for our organism as well (we are workign with both freshwater and marine microalge), it is like collaborative project for mutual benefits. incase if you are a PhD scholar or PDF, kindly pass this info to your mentor.
Look forward to hear from you,
Hi Muthu,
Generally, the fungal assisted flocculation could be performed by two techniques. The first technique is the co-cultivation of microalgae with fungal pellets. This technique needs two steps of pelletization of fungal cells and co-cultivation with microalgae which required at least 72 and 48 h, respectively. The second technique is the co-pelletization in which the fungi grow and simultaneously flocculate microalgal cells in their pellets. This technique could reduce the operating steps and increase the overall productivity. In this paper, the first technique was used for our study. The microalgae was harvested within 10 min by 94%. The fungal Trichoderma is oleaginous fungi strain (>20% lipid content) which was used for this purpose. Therefore, after harvesting the biomass and lipid yields of microalgae-fungi pellets could improve. However, it is not possible to separate the microalgae from microalgae-fungi pellets due to entrapment in the pellets and attachment with exopolysaccharides, possibly secreted by the fungi.
I am working PhD project under supervision of Prof.Benjamas Cheirsilp, please contact her if you need to collaborate on your project.
If you have any question, please feel free to contact me.
Best regards,
Sirasit Srinuanpan
Thanks for your response Dr. Sirasit Srinupan. I will be grateful if you could forward my concern to your mentor. Since you are the scholar directly involved int his study, I request you to be a moderator of this collaboration.
Thanks.
