Method for Metabolic Re-Modelling Chlorella Fc2 Strain at Lipid Induction Phase
Abstract

The invention presents a proteomic landscape of lipid accumulation pathways in Chlorella sp. FC2 IITG, an oleaginous microalga, during nitrogen (N) starvation. Through sophisticated proteomic techniques, including iTRAQ and DIGE, validated by MRM and Western blotting, the study identifies key proteins associated with various metabolic processes, stress response, and photosynthesis. Notably, the temporal proteome analysis reveals critical time points correlating with significant changes in lipid content, shedding light on the intricate interplay of metabolic pathways under nutrient stress. The findings not only deepen our understanding of lipid biosynthesis in microalgae but also present potential targets for genetic manipulation to enhance lipid yields. Ultimately, this research contributes to the development of sustainable bioenergy resources, particularly algae-based biofuels, addressing the global imperative to transition from fossil fuels.

Problem Statement

The current challenge lies in optimizing the efficiency of biofuel generation from renewable sources, particularly microalgae. Despite their high lipid content and adaptability to non-arable land, the full potential of microalgae remains untapped. Understanding the molecular mechanisms driving lipid accumulation in microalgae, especially under stress conditions like nitrogen starvation, is crucial for enhancing biofuel production efficiency.
