    Area of Science:

    • Biochemistry
    • Microbiology
    • Mycology

    Context:

    • Lipid profiles are crucial for understanding microbial physiology and potential applications.
    • Aureobasidium (Pullularia) pullulans is a yeast with diverse metabolic capabilities.
    • Characterizing microbial lipids aids in identifying novel bioactive compounds.

    Purpose:

    • To determine the fractional composition of free and bound lipids in Aureobasidium (Pullularia) pullulans.
    • To identify and quantify the fatty acid composition of these lipid fractions.
    • To analyze key lipid parameters such as ester, iodine, and saponification numbers.

    Summary:

    • Preparative Thin-Layer Chromatography (TLC) and Gas-Liquid Chromatography (GLC) were employed to analyze lipids from Aureobasidium (Pullularia) pullulans.
    • Bound lipids contained a significant dark brown fraction (27.76 ± 0.5%) resembling melanin.
    • Predominant fatty acids in both free and bound lipids were C16:0 and C18:1+C18:2, with unsaturated fatty acids exceeding saturated ones.

    Impact:

    • Provides detailed lipidomic data for Aureobasidium (Pullularia) pullulans.
    • Highlights a potential melanin-like compound within the bound lipid fraction.
    • Offers insights into the fatty acid profiles relevant for biotechnological or industrial applications.
