The green microalga Haematococcus pluvialis accumulates astaxanthin, a potent antioxidant pigment, as defense mechanism against environmental stresses. In this study, we investigated the technical feasibility of stress-based method for inducing astaxanthin biosynthesis in H. using electric stimulation two-chamber bioelectrochemical system. When cathodic (reduction) current 3 mA (voltage: 2 V) w...

The microalga Haematococcus pluvialis Flotow is one of the natural sources of astaxanthin, a pigment widely used in salmon feed. This study was made to discover optimal conditions for biomass and astaxanthin production in H. pluvialis from Steptoe, Nevada (USA), cultured in batch mode. Growth was carried out under autotrophic (with NaNO3, NH4Cl and urea) and mixotrophic conditions (with 4, 8, 1...

Microalgae biomass can produce high quantities of biochemicals that be used in various applications such as biodiesel, biogas, and aquaculture feed. The potential sterilizing wastewater for microalgae-based treatment on a lab scale is well introduced. However, the operation cost large-scale microalgae cultivation plants if using sterilising growth medium. present study aimed to evaluate Scenede...

The carotenoid pigment astaxanthin has important applications in the nutraceutical, cosmetics, food and feed industries. Haematococcus pluvialis is the richest source of natural astaxanthin and is now cultivated at industrial scale. Astaxanthin is a strong coloring agent and a potent antioxidant - its strong antioxidant activity points to its potential to target several health conditions. This ...
