Hello,
I am looking for information about the optimal parameters for the production of chlorella vulgaris.
The company for which I work is an engineering office specializing in anaerobic digestion. In this context, it has already helped the customer to implement a biogas plant in Luxembourg, which has been operating for several years. This customer wants to add to his biogas plant, a production unit of algae (chlorella), which will allow for the extension of CO2 (from biogas purification) and heat of biogas plants. From data sourced from the University of Liege (Belgium), we have found out that when producing tubes with a diameter of 5cm, we can obtain 1 g of dry matter / day / liter. However, I would like to know if existe mabe other- better sizes of used tubes or light requirements in such an installation based on the principle of photosynthesis (LED lamp lit). The breeding pool have 25 tubes with a capacity of 10m³ each tube (250m³ in total). I have problems with estimating the amount of algae needed to be placed in a single tube so that the process can achieve such efficiency. I will be very grateful for any additional information that would help me in this project.
Although you can find plenty of information about Chlorella production, please contact with Prof.Oya Işık or Assoc.Prof.Leyla Uslu at Çukurova University, Fisheries Faculty, Oya Işık is Head of Algae and Plankton Laboratory of that Faculty.
Good luck.
Thank you for the opportunity to contact in this case, with the right people.
What is the mode of operation - batch or continuous? C. Vulgaris is highly robust and it has been studied extensively. You should be able to get precise information for your strain. Generally, light is the most crucial parameter, and using :LEDs, you can optimize both the wavelength and the intensity to maximize productivity. If you know the growth rate of the cell line, you should be able to make some calculation on the inoculum size and productivity.
Thank you for the information. It was quite a panicky question when confronted with the subject of the production of algae on the industrial scale. At this point I became familiar with this subject, so I found all the information I needed. Thank you for your help.
Chlorella vulgaris is one of microalgae that can grow in wide range of varied conditions. From my experience with microalgae cultivation, you can use one of common media for freshwater microalgae cultivation such as KC, Khul or BG11 at temperature of 25 C and light intensity of 100 Um photon/m2.s with aeration using air pumps used for aquarium. Of course, you should work under sterilized conditions to prevent contamination.
Using municipal wastewater as growth medium showed high efficiency to grow C. vulgaris as well.
Best wishes
