Neochloris oleoabundans from nature to industry: a comprehensive review

Abstract

Microalgae technology has been extensively studied during the last two decades. Thousands of species were isolated, and few are currently used in the market for multiple purposes. The current comprehensive review focuses on a promising species named Neochloris oleoabundans. It encompasses a historical overview of the species followed by a detailed description of its taxonomy, ecophysiology and morphology. Furthermore, a thorough screening is conducted to outline the production conditions employed to grow the microalga. In addition, multiple cell disruption and fractionation methods previously applied on N. oleoabundans are described and discussed together with the value chain creation after applying all the unit operations.

Characterization of Neochloris oleoabundans under Different Cultivation Modes and First Results on Bioactivity of Its Extracts against HCoV-229E Virus

“…Furthermore, both autotrophic and mixotrophic algae obviously contained proteins; they were more abundant in A-cells than in M-ones, even if the total protein content in total extracts used for antiviral tests gave an opposite result ( Figure 3 A, Table 1 ). This unexpected result could be linked to different efficiency of cell wall disruption and consequent release of proteins from N. oleoabundans cultivated under different growth conditions, as [ 58 ] observed for the same alga under fresh or marine N-depleted or -repleted waters. In addition, that finding could be the result of different extractability and solubility of proteins in an aqueous solution with respect to the extraction buffer.…”

Metabolic Responses of the Microalga Neochloris oleoabundans to Extracellular Self- and Nonself-DNA

“…The cultivation of this microalgae is possible in both freshwater and marine water conditions [ 19 ]. Due to its high growth rate and adaptability, N. oleoabundans biomass has a wide range of applications, including the production of bioplastics, cosmetics, nutraceuticals, and vegetable oils production, among others [ 20 ]. The characteristic of these microalgae, which has been of interest to the scientific community and some industrial sectors, is its ability to accumulate up to 54% of its dry weight in total lipids under nitrogen deficiency [ 21 ].…”

“…The characteristic of these microalgae, which has been of interest to the scientific community and some industrial sectors, is its ability to accumulate up to 54% of its dry weight in total lipids under nitrogen deficiency [ 21 ]. Because of this property, it has been considered a study model for biodiesel production [ 20 ]. The main intracellular lipid components of these microalgae are C16:0, C18:0, C18:1, C18:2, and C18:3 type.…”
