A novel approach for converting non-edible plant biomass into single-cell protein and oil (SCPO) via consolidated bioprocessing has been established, leveraging aerotolerant thermophilic cellulolytic consortia consisting mainly of Thermoanaerobacterium thermosaccharolyticum, Sporolactobacillus spp. Clostridium sensu stricto to achieve the rapid complete conversion crystalline cellulose a consistent cocktail lactate, acetate ethanol. This is an excellent substrate cultivating organisms SCPO production food feed applications, including Cyberlindnera jadinii, Yarrowia lipolytica Corynebacterium glutamicum. Cultivation on this resulted in yields (YX/S) up 0.43 ± 0.012 g/g, indicating yield from (YX/Cellulose) 0.27 0.007 g/g (dwb). The resulting was rich (42.5% 57.9%), essential amino acids (27.8% 43.2%) lipids (7.9% 8.4%), with unsaturated fatty acid fractions 89%. Unlike fermentation feedstocks derived easily digested (i.e., waste), applied cellulosic biomass, mixed-culture bioconversion can be carried out without adding expensive enzymes. two-stage unlock as untapped feedstock production, potential strengthen resiliency circularity systems.
