Efficient superantioxidant and biofuel production from microalga Haematococcus pluvialis via a biorefinery approach.

摘要: Abstract A biorefinery approach was implemented to produce a superantixoident, i.e., astaxanthin, and biofuels, ethanol biogas, from the biomass of microalga Haematococcus pluvialis. The hydrolysis residual obtained astaxanthin extraction conducted using α-amylase glucoamylase for α-glucans mixture cellulases β-glucan hydrolysis. Four different hyudrolysis processes were employed efficiency 97.2% over total glucan obtained, which then fermented 0.21 g ethanol/g biomass. residuals fermentation anaerobically digested biomethane. yield biomethane 264.8 ml/g volatile solids, 2.9 fold greater than methane raw microalgal Overall, process consecutive production biogas H. pluvialis recognized as promising 45.8 g 7095.3 KJ energy per Kg
