Item type:Publication, Impact of Bio-calcium from Nile Tilapia Bone as a Supporting Material on the Stability Enhancement of Immobilized Probiotics(2025-07-01); Kingwascharapong, PassakornThis study presented the potential of bio-calcium powder (BC) from Nile tilapia bone on enhancement of probiotics (Lactobacillus acidophilus) stability as supporting material in probiotic immobilization and novel nutritive resource, particularly calcium. Combined immobilization techniques of absorption using BC at different concentrations (0, 10, and 15%) and encapsulation using fish collagen peptide (CP) (10%) were applied. Immobilized probiotics (IP) were investigated for resistance through various adverse conditions, including freeze-drying, severe pH and temperature levels, and gastro-intestinal tract (GI) conditions. After freeze-drying, all IPs showed resistance with > 90% survivability. Under various pHs, all samples revealed non-significant differences on cell survival under neutral and alkaline conditions throughout the tested incubation period (P > 0.05). Notably decreased survivability was detected in IP with BC compared to other samples, especially under acid condition. IP with 10 and 15% BC (IP-10 and IP-15) showed higher stability to thermal condition (55 °C) with increased incubation time, compared with those without BC (IP-0). After GI digestion, IP with BC reveals a better survivability with greater recovery ability, compared with IP-0 (P < 0.05). Calcium solubility increased with BC level in a dose-dependent manner (P < 0.05). Based on morphology and microscopy analysis, IP with BC illustrated cells attached to the rough surface of BC, which was coated with collagen peptide. Elemental mappings and distribution content suggested BC could be a great supporting material and calcium resource, particularly IP-15. Therefore, the absorption by BC together with encapsulation by collagen peptide could render a highly stable immobilized probiotic and a good calcium resource. - Some of the metrics are blocked by yourconsent settings
