Microbial synthesis of poly- γ -glutamic acid ( γ -PGA) with fulvic acid powder, the waste from yeast molasses fermentation
[post]
2020
unpublished
Background: Molasses is a wildly used feedstock for fermentation, but it also poses a severe wastewater-disposal problem worldwide. Recently, the wastewater from yeast molasses fermentation is being processed into fulvic acid (FA) powder as a fertilizer for crops, but it consequently induces a problem of soil acidification after being directly applied into soil. In this study, the low-cost FA powder was bioconverted into a value-added product of γ-PGA by a glutamate independent producer of
