With
the recent advancements in molecular and cellular biology; potentials of algae
are currently identified as unpredictably rapid, they thus progressively
continue to fascinate researchers, governments, farmers and especially
stakeholders investing on bioenergy, biofuels, pharmaceuticals, nutraceuticals
and feed. Moreover, algae present a highly sustainable and natural bioresource
for increasing world population food requirements. Due to their broad yet
low-cost biomass potentials related to biofuels, pharmaceuticals,
nutraceuticals, and human health, their considerable advantages in most
agricultural applications were underestimated over last two decades.
In
today’s modern agriculture, the potentials of photosynthetic and atmospheric
CO2-fixing algae (both blue-green eukaryotic algae and Gram-negative
prokaryotic cyanobacteria) started as recognized more efficiently. Algae are
capable of promoting soil nutrient availability, organic carbon/metal ion
content and fertility. When applied, it enhances seed germination, plant
growth, and crop yields by stimulating of the enrichment of beneficial
microbiota in the soil. Both green algae and cyanobacteria are also able to
produce numerous plant growth promoting metabolites such as growth hormones,
polysaccharides, antimicrobial compounds, siderophores etc. Algae naturally
also produce biostimulant and biofertiliser metabolites which considerably
stimulate plant growth and development under optimal and stressful conditions.
Some of these metabolites are essential to restrict the colonization of plant
pathogenic bacteria fungi and even nematodes, serving as natural biopesticides,
thereby standing as sustainable alternatives to synthetic fertilizers,
stimulants and pesticides.
Beyond
their plant-protective, -promoting and -growth enhancing effects, here we
report the metabolic engineering of industrial algae strains essential for
biofuels production or waste water treatment, to improve their targeted crop
protection, biopesticide and environmental potentials through integrated
operations.
