Summary: The study aimed to investigate the pretreatment characteristics of food waste by Bacillus licheniformis and Bacillus oryzaecorticis, and their contribution to the structure of fulvic acid and humic acid. The results showed that microbial treatments led to a decrease in pH and Bacillus oryzaecorticis degraded starch and released reducing sugar, providing OH and COOH to fulvic acid molecules. Bacillus licheniformis showed a positive effect on the structure of humic acid, which had higher OH, CH3 and aliphatics. This study provides evidence for the application of Bacillus licheniformis and Bacillus oryzaecorticis in waste management.

Summary: Understanding the behavior of heavy metals in the environment through humic acid (HA) is crucial, but there is a lack of knowledge on the control of HA's structure organization and its reactivity. This study used the fractionation method to reduce the heterogeneity of HA and analyzed its chemical properties. The results showed that the adsorption capacity for lead ions (Pb2+) followed the order of HA-1 > HA-2 > HA-3. Linear analysis indicated that the adsorption capacity was positively correlated with acid groups, carboxyl groups, phenolic hydroxyl groups, and the number of aliphatic chains. Structural differences and the number of active sites play an important role in adsorption.

Summary: Bacterial cellulose (BC), a biopolymer produced by different microorganisms, can be used as a matrix for the introduction of other polymers, resulting in composite materials with improved mechanical properties and prebiotic activity. This study demonstrated that the probiotic strain Lactobacillus rhamnosus GG showed better growth when stimulated by pullulan (PUL) compared to other microbial polysaccharides. By co-cultivating Komagataeibacter xylinus and Aureobasidium pullulans, BC/PUL biocomposites with prebiotic properties were successfully produced. The inclusion of PUL in BC was confirmed through gravimetric analysis and microscopic observation. The co-cultivation approach also led to enhanced fiber aggregation and binding, resulting in significant improvements in the mechanical properties of the composites.

Summary: This study investigates the effects of carbon sources and culture media on the production and structural properties of bacterial cellulose synthesized by Medusomyces gisevii. Results show that Medusomyces gisevii has higher cellulose yields in media with sugar concentrations close to 10 g L-1, with glucose leading to higher yields compared to sucrose. The cellulose produced from sucrose has higher crystallinity and surface roughness.
