Comparison of lactic acid yields from different substrates using Lactiplantibacillus plantarum strains, indicating effective waste utilization.

Lactic acid production varied by substrate, with distiller’s dried grains yielding 20 g/L LA.
Lactiplantibacillus plantarum strains effectively utilized sugars from multiple agro-industrial waste materials.
The production from wood chips was significantly lower, achieving only 5 g/L LA from 10 g/L reducing sugars.
A mathematical model was developed integrating Compertz and Luedeking–Piret equations to describe the fermentation process.

Naydenova et al. (2025) studied this question.
