摘要: Aims: To partially purify and characterize bioemulsifiers produced by two new marine Halomonas species, TG39 TG67, to compare their emulsifying activities with those of commercial emulsifiers. Methods Results: The production emulsifiers HE39 HE67 was achieved from glucose-supplemented broth, recovered cell removal, concentration ultrafiltration, precipitation salt ethanol, lyophilization. Purification chemical analysis revealed both be glycoproteins high molecular weight a notably content protein uronic acids. Physical characterization showed effectively emulsify wide range food oils under neutral acidic pH conditions withstand acid temperature treatment. Conclusions: these glycoprotein were comparable and, certain conditions, superior tested (xanthan gum, gum arabic lecithin). They show the highest reported derived species. Significance Impact Study: These strains, produced, appear promising candidates for further development in applications requiring that are natural compatible existing emulsifiers.
