PROSPECTS OF MICROALGAE BIOREFINERY

Microalgae have been the immense source of global attraction as a
highly potential and promising renewable biomass source of energy,
biomitigation and sustainable valuable products. Biotechnological
explorations of the underutilized bountiful indigenous algae diversity of
NE India, have potentially opened a new avenue for sustainable product
development including green energy production. Several microalgae species
have been marked as potential source of naturally occurring high valued
products such as lipids, vitamins, proteins, carbohydrates, antioxidants,
colorants, food supplements and other bioactive molecules. The North East
India, apart from being one of the mega biodiversity hotspots in the world, has
bestowed upon with vivid freshwater microalgal resources. These diverse bio-
resources of the region are yet to be explored to the extent for their potential
biotechnological applications. Recent studies carried out are envisaged with
the isolation and screening of freshwater biodiesel potential microalgae of
the region yielding with the isolation of 24 indigenous freshwater microalgae
species, which require further works for possible commercial utilizations
and biotechnological applications. Among the isolated microalgae, Chlorella
sp, Botryococcus braunii, Ankistrodesmus sp, Scenedesmus sp, Euglena
sp, Haematococcus sp, Navicula sp, and Nitzchia sp are known to be a few
oleaginous microalgae noteworthy for biofuel production. Oil (lipid) contents
werequantitativelyevaluated in laboratoryculturesof isolatedAnkistrodesmus
sp, B braunii, Scenedesmus sp, Chlorella sp and Chlorococcum species. The
lipid content of some of the isolatedmicroalgae species grown in normal BG11
medium were found to be in the range between 11.3–42.0% of dry weight.
Analysis of the carotenoid contents of the selected native microalgae species
also revelled higher content of lutein, lycopene and astaxanthin, which can be
produced as other high valued products for additional fund generation during
liquid biofuel production. The liquid hydrocarbon producing green microalgae
B braunii is found to be significant among the isolated microalgae, which
exhibited hydrocarbon in the range between 21.9-60.7% of dry weight. Some
of these isolated microalgae e.g. Scenedesmus sp (8-56% protein; 10-52%
carbohydrate), Chlorella sp (51-58% protein; 12-26% carbohydrate), Euglena
sp (39-61% protein; 14-18% carbohydrate and 14-20% lipid) are also reported
to contain high percentage of carbohydrate and protein in addition to its
moderate to high lipid content, which justify the enough scope for utilization
of these species in developing a technology for potential biofuel production
and other value added products of commercial potential based on biorefinery
approaches.
