Production of Hydroxy Fatty Acids and 5-Hydroxy Methyl Furfural from Microalgal Biomass: An Integrated Biorefinery Perspective Involving Chemical and Enzymatic Conversion.

A novel biorefinery process utilizing microalgal biomass has been developed, focusing on the enzymatic biotransformation of microalgal fatty acids in hydroxy fatty acids (HFAs) and the chemical conversion of the cellular debris to 5-hydroxymethyl furfural (5-HMF). First, the process was demonstrated using the dry biomass of the microalgal strains sp. , and sp.

Systematic screening for the biocatalytic hydration of fatty acids from different oily substrates by Elizabethkingia meningoseptica oleate hydratase through a Design-of-experiments approach.

The edible plant oils production is associated with the release of different types of by-products. The latter represent cheap and available substrates to produce valuable compounds, such as flavours and fragrances, biologically active compounds and bio-based polymers. Elizabethkingia meningoseptica Oleate hydratases (Em_OhyA) can selectively catalyze the conversion of unsaturated fatty acids, specifically oleic acid, into hydroxy fatty acids, which find different industrial applications.

Lutein Production and Extraction from Microalgae: Recent Insights and Bioactive Potential.

Microalgae have been reported to be excellent producers of bioactive molecules. Lutein is a pigment reported to have various beneficial effects for humans, and especially for eye well-being. In the current review, we summarize various methods that have been developed to optimize its extraction and bioactivities reported for human health.

Flashing lights affect the photophysiology and expression of carotenoid and lipid synthesis genes in Nannochloropsis gaditana.

Nannochloropsis gaditana is a promising microalga for biotechnology. One of the strategies to stimulate its full potential in metabolite production is exposure to flashing lights. Here, we report how N.

Flashing light emitting diodes (LEDs) induce proteins, polyunsaturated fatty acids and pigments in three microalgae.

As the periodic emission of light pulses by light emitting diodes (LEDs) is known to stimulate growth or induce high value biocompounds in microalgae, this flashing light regime was tested on growth and biochemical composition of the microalgae Nannochloropsis gaditana, Koliella antarctica and Tetraselmis chui. At low flashing light frequencies (e.g.

Human Intrinsic Factor Expression for Bioavailable Vitamin B Enrichment in Microalgae.

Dietary supplements and functional foods are becoming increasingly popular complements to regular diets. A recurring ingredient is the essential cofactor vitamin B (B). Microalgae are making their way into the dietary supplement and functional food market but do not produce B, and their B content is very variable.
