Research Project: Mini-Pilot Scale Production of Biofuel and Animal Feed from Heterotrophic Algae

Location: Tropical Plant Genetic Resources and Disease Research

2013 Annual Report


1a.Objectives (from AD-416):
The objective of the project is to produce mini-pilot scale levels of algae oil and algae meal from heterotrophic algae that use waste papaya fruit as a carbon source.


1b.Approach (from AD-416):
The research team at PBARC has successfully grown heterotrophic algae on waste papaya fruit and recovered economic levels of algae oil and algae meal under laboratory conditions. The team now plans to produce mini-pilot scale levels of algae oil and algae meal in a 150 liter capacity bioreactor. The funds will be used to purchase the reactor and some supplies. Pacific Basin Agricultural Research Center (PBARC) has the personnel and space to run the bioreactor.


3.Progress Report:

The research team at the Pacific Basin Agricultural Research Center (PBARC) has successfully grown heterotrophic algae on waste papaya fruit and recovered high levels of algae oil and algae meal under laboratory conditions. The team now wants to produce mini-pilot scale levels of algae oil and algae meal in a 150 liter capacity bioreactor. The state funds have recently been received by PBARC and are being used to purchase the bioreactor.

This research is related to sub-objective 3c of the inhouse parent project, "Develop improved practices for sustainable, tropical/subtropical, diversified crop production that will serve as an industry model for zero waste".
