Growth Performance, Biochemical Composition and Nutrient Recovery Ability of Twelve Microalgae Consortia Isolated from Various Local OrganicWastes Grown on Nano-Filtered Pig Slurry / S. Min, M.

Abstract:
This paper demonstrated the growth ability of twelve algae-microbial consortia (AC)
isolated from organic wastes when a pig slurry-derived wastewater (NFP) was used as growth
substrate in autotrophic cultivation. Nutrient recovery, biochemical composition, fatty acid and amino
acid profiles of algae consortia were evaluated and compared. Three algae-microbial consortia, i.e., a
Chlorella-dominated consortium (AC_1), a Tetradesmus and Synechocystis co-dominated consortium
(AC_10), and a Chlorella and Tetradesmus co-dominated consortium (AC_12) were found to have the
best growth rates (µ of 0.55 ± 0.04, 0.52 ± 0.06, and 0.58 ± 0.03 d−1
, respectively), which made them
good candidates for further applications. The ACs showed high carbohydrates and lipid contents but
low contents of both proteins and essential amino acids, probably because of the low N concentration
of NFP. AC_1 and AC_12 showed optimal ω6:ω3 ratios of 3.1 and 3.6, which make them interesting
from a nutritional point of view.
