“…Этот полимер стал известен только в последнее десятилетие, но по своим свойствам, в частности способности образовывать гели в присутствии солей, он похож на альгинат, хотя в отличие от него может образовывать гели с различными ионами, например, ионами натрия, а не только кальция. Предлагается использовать смесь ацилированной и деацилированной формы геллановой камеди с аскорбиновой кислотой для получения съедобной пленки с антиоксидантными свойствами [65]. Показано, что увеличение содержания в пленке деацилированного полимера и ионов кальция повышает способность аскорбиновой кислоты подавлять процесс ферментативного побурения, которое приводит к появлению коричневого цвета, например, при хранении нарезанных яблок.…”

The purpose of this study aimed to evaluate the potential and performance of Lactobacillus plantarum 1 UHCC (L.plantarum 1UHCC) bacteria as bio-hydrolyzer of the food industry in Indonesia. As much as 100g of fresh hide from Balinese cattle were used as a substrate. The fermentation time was carried out at 3 time levels, namely: 24 hours (T-24); 48 hours (T-48) and 72 hours (T-72). The bacteria were used L.plantarum which was isolated from milkfish extract. The results showed that in the solution of L.plantarum bacteria using collagen substrate of cattle hide, pH values were increased and the lactic acid levels were decreased significantly. The pH value and the lactic acid level of the solution were respectively around 5.77±0.03-6.13±0.02 and 1.65±0.26-2.02±0.05%. The total bacteria has increased and dissolved protein has decreased for fermentation time, but in general it is not significant. Total bacteria and dissolved proteins respectively 4.5±0.98-5.5±2.29 Log10CFU/mL and 36.98±3.37-40.25±1.54 mg/mL. The application of 24 hours (T-24) fermentation time to L.plantarum bacteria using collagen substrate of cattle hide skin was considered as the optimum time to be applied in the fermentation process. Bacteria L.plantarum 1UHCC has the ability to hydrolyze collagen protein components, especially collagen extracts from cattle hide. Bacteria L.plantarum 1UHCC has the potential to be developed as a bio-hydrolyzer organism. Bacteria L.plantarum 1UHCC plays a very important role in the development of the food industry, especially in Indonesia. Keywords: Bacteria, Cattle hide, Collagen, Fermentation, L.plantarum 1UHCC

“…Microbial polysaccharides, such as gellan, pullulan, xanthan, bacterial cellulose, curdlan, and GalactoPol have been applied in the development of stand‐alone films. In addition, some of those polysaccharides, mostly gellan, pullulan, and xanthan, have been also applied in edible coatings, which consist on a relatively thin layer of material with a specific composition applied and formed directly on food product's surface, which may be eaten along with the product…”

“…Interesting barriers based on microbial polysaccharides have been referred, such as antimicrobial coatings against food spoilage bacteria based on pullulan and tymol, nanocomposite thin films of pullulan and silver with antifungal activity; as well as probiotic‐residing pullulan/starch edible films . In addition, edible films based on gellan have been evaluated as carriers for stabilizing ascorbic acid, for nutritional purposes, and antioxidant effect; as well as other antioxidants (e.g. l ‐acetylcysteine and glutathione) to be applied on fresh‐cut fruits …”

Microbial polysaccharides are characterized by high molecular structure variability which translates into a wide range of different properties offering interesting opportunities for application in many different areas, including membrane-based products and processes. Due to their new or improved properties, microbial polysaccharides can replace plant, algae, and animal products, either in their traditional or in new applications. The main constraint to their wider use is the production costs that are still higher than that of other natural and synthetic polymers. The current applications of microbial polysaccharide membranes in medical, food, and industrial processes are outlined. The limitations still faced by these membranes and the requirements for obtaining innovative products and processes are also addressed.
