Exploitation of microorganisms (i.e., biotransformation) in beverages, food and feed production is well established since ancient times in human culture; one recent example in the field of food formulation is the use of biomasses derived from cyanobacterium Spirulina platensis used as supplement product in order to fulfill the increasing demand of non-animal proteins, as for the vegan diet.

In this context, the principal project aim is to use microorganisms, mainly oleaginous yeasts and heterotrophic microalgae, described in literature for their highly efficient accumulation of  PUFA, DHA and EPA, in order to extract omega-3 and carotenoids. The principal aspects investigated in the project is the selection of specific oleaginous microorganisms able to efficiently use crude glycerol as carbon source and the optimization of growth conditions for the production of a panel of fatty acid containing the desired compositions in terms of Long Chain n-3. The second phase consist in the formulation of fish feed pellets, containing omega-3 and carotenoids. The biotechnological oil (MO=microbial oil) produced by MYSUSHi, as substitute for Fish Oil, will allow to regain a correct amount of EPA and DHA in the fish diet and therefore to improve the nutritional value of it.
