“…Similar levels of productivity could also be reached under mixotrophic conditions with the addition of potassium as an inducing agent [202]. More recently, a study developed a strategy to enhance effectively astaxanthin and lipid production in H. pluvialis under mixotrophic conditions and low light by the addition of glycerol as an organic carbon source [203].…”

Astaxanthin shows many biological activities. It has acquired a high economic potential and its current market is dominated by its synthetic form. However, due to the increase of the health and environmental concerns from consumers, natural forms are now preferred for human consumption. Haematococcus pluvialis is artificially cultured at an industrial scale to produce astaxanthin used as a dietary supplement. However, due to the high cost of its cultivation and its relatively low biomass and pigment productivities, the astaxanthin extracted from this microalga remains expensive and this has probably the consequence of slowing down its economic development in the lower added-value market such as food ingredient. In this review, we first aim to provide an overview of the chemical and biochemical properties of astaxanthin, as well as of its natural sources. We discuss its bioavailability, metabolism, and biological activities. We present a state-of-the-art of the biology and physiology of H. pluvialis, and highlight novel insights into the biotechnological processes which allow optimizing the biomass and astaxanthin productivities. We are trying to identify some lines of research that would improve the industrial sustainability and economic viability of this bio-production and to broaden the commercial potential of astaxanthin produced from H. pluvialis.

“…However, sometimes may be one kind of carbon source could be the best choice to have the highest biomass yield, while the other type would be the optimum one for lipid production. In this line it was found that, even though glycerol could not increase the biomass production of Haematococcus pluvialis, it upgraded the lipid content of the microalgae as 36.8% [52]. For Tetraselmis sp.…”

Microalgae are considered as an outstanding feedstock to produce high value lipid products like biodiesel and biomedicine. Reaching commercial maturity in this field is possible in the case of maximizing lipid yield and minimizing prime costs. In order to clarify the best features of carbon source (for microalgae cultivation) to reach optimum efficiency of biomass and lipid production, this paper reviews the merits and demerits of different trophic modes as well as type and concentration of carbon source. Furthermore carbon supplementation for large scale microalgae cultivation and lipid production is discussed as an economical point of view.

“…Under stresses, H. pluvialis increases the expression of related enzymes genes to biosynthesis and accumulate more astaxanthin. Many previous studies have shown that some astaxanthin synthesis genes may affect the astaxanthin synthesis in H. pluvialis [35][36][37][38]. For example, both β-carotene hydroxylase and β-carotene ketolase were important enzymes in astaxanthin pathway in H. pluvialis.…”
