The aim of the research is to improve the quality and nutritional value of the alfalfa haylage applying the «Green-grass 3×3» biopreservative with herbage. Current biological preparations contain live cultures of specially selected lactic, propionic acids, and sporogenous bacillus, a complex of amino acids, enzymes, vitamins and minor nutrient elements. Preparation use with herbage during haylage leads to intensification the lactic acid fermentation, im-provement of ratio of organic acids, increase the content of nutrients and ensuring their reliable safety during stor-age. The research was carried out at the milk production complex of «Radna» LLC in the Samara region. The re-search was provided involving Holstein and Ayrshire breeds. The haylage was fed to cows in the amount of 24 kg as part of a balanced feed mixture in accordance with the casein diet. As a result of applying a bio-preservative with herbage, the content of organic acids in the ready made feeds increased by 0.54%, including lactic acid – by 0.80%. The dry weight increased by 4.6%, available energy – by 37.4%, energy feed units – by 9.1%, digestible protein – by 13.8%, crude fiber – by 0.9%. Feeding the cows haylage with a bioconservative increased the meta-bolic processes in the tripe of animals. Ciliata weight in the ruminal fluid of Holstein cows increased by 29.0%, Ayr-shire – by 25.8%, number of bacteria, respectively, by 26.5 and 27.5%. As a result, the content of total nitrogen in-creased by 15.0-15.1%, protein nitrogen – by 40.4-42.9%, and ammonia, on the contrary, decreased by 40.0-40.6%. The content of volatile fatty acids decreased by 12.6-16.2%, while the proportion of acetic acid increased by 7.73-8.71%. All this had a positive effect on the digestibility of nutrients by the animals of the experimental groups. The digestibility of the dry weight of the feed increased, respectively, by 4.14-4.57%, and its components – by 4.23-6.97%.

Relevance. Fermentation of cabbage is a common way of processing, which allows to preserve and strengthen its useful qualities. To date, breeders have proposed a significant number of varieties and hybrids of cabbage, each of which has its own individual biochemical characteristics. Traditional sauerkraut is carried out after harvest. Long storage can affect the change in the content of organic acids and sugars in cabbage.Methods. The aim of the work was to study the parameters of the fermentation process of eight varieties and hybrids of cabbage by selection in the Federal State Budgetary Scientific Institution Federal Scientific Vegetable Center by the intensity of sugar reduction, accumulation of organic acids, organoleptic parameters and activity of lactic acid microorganisms. Fermentation was carried out after a 5-month period of storage of heads.Results. The results showed that the storage period did not affect the fermentation result of most of the studied varieties and hybrids of cabbage. There are varietal differences in the initial content of mono-and disaccharides, organic acids, which affected the fermentation process. The increased content of malic acid in the variety population Podarok, F1 Severyanka contributed to the slowdown of the first stage of fermentation. Varietal features of the Parus population contributed to the slowdown of the first and second stages of fermentation, which was manifested in a decrease in the rate of destruction of sugars. Variety Zymovka 1474 in the process of processing by fermentation accumulates a significant amount of succinic acid, which can characterize its special difference among the studied varieties and hybrids. The best organoleptic characteristics were distinguished by hybrids of fermented cabbage F1 Likova, F1 Natali, F1 Mechta and F1 Snezhinka. The results of the study suggest that the processing of cabbage by fermentation should take into account its individual varietal biochemical features. This will not only preserve the valuable nutritional properties of the cabbage itself, but also strengthen them by optimizing the natural process of lactic acid fermentation. The result will be the best organoleptic effect achieved by an optimal combination of lactic and citric acids and mono-sugars.

Using of silage and haylage of forage legumes in ruminant nutrition and promotion of promoting proper forage conservation techniques should be an important strategy in livestock production in our country. Forage legumes are difficult to ensile, so it is necessary to apply the starter culture of selected strains of lactic acid bacteria that support the ensiling process and prevent bacterial butyric fermentation and thus contribute to the preservation and improvement of silage and haylage quality. In this paper, the influence of bacterial inoculant ?Silko for alfalfa? on the quality of silage and haylage of alfalfa in two separate trials is presented. The inoculant is a combination of homofermentative lactic bacteria Lactobacillus plantarum and Pediococcus spp. The first-cut alfalfa in the second year was used for silage and haylage. The silage was examined in mini-silos in the laboratory, and the haylage at the cattle farm where the plant material was cuts were collected in experimental silo bags. The treatments were control (untreated silage, i.e. haylage) and silage, i.e. haylage treated with inoculant ?Silko for alfalfa? (rate of 5 ml t-1 fresh material). The silages were analyzed after 90 days, and haylage after 40. The inoculant ?Silko for alfalfa? has been found to maintain the nutritive value of silage and haylage and to improve their chemical, energy and fermentation parameters relative to the control. Since ?Silko for alfalfa? positively affects the correct lactic acid fermentation of silage and haylage and contributes to a lesser loss of nutritional value and energy it is expected that it can promote a high level of productivity of ruminants, and thus contribute to the growth of profit in livestock production.

Naniura is a traditional Batak food that is made without going through a heating process, but is made through a fermentation process using acid and salt. The use of acid and salt acts as a preservative because it can inhibit the growth of pathogenic microbes and spoilage microbes. In addition, naniura fermentation has the potential to be a growth medium for lactic acid bacteria, most of which strains can act as probiotics. However, the potential for probiotic naniura is still rarely studied and studied, so this review article is made to examine the potential for probiotic naniura and the health effects that can be obtained. The writing of this journal uses the literature study method, namely by collecting information from various scientific sources. Several studies have shown that naniura contains lactic acid bacteria that can act as broad-spectrum antimicrobials and can specifically inhibit the growth of Salmonella typhi, Bacillus cereus, Clostridium botulinum, E. coli and S. aureus. Consuming probiotic foods can have a positive effect on health, including improving the quality of the digestive tract, increasing the immune system in the body and degrading lactose so that it can be used for lactose intolerant sufferers.

Abstract Lactobacillus brevis PCM 2570 is a strain of lactic acid bacteria, i.e. probiotic bacteria whose major fermentation product is lactic acid. The efficiency of lactic acid production is limited by the value of ambient pH. This study aimed to increase the survival of this bacterial strain at a reduced pH (3.9), which would result in an increased yield of lactic acid fermentation. In our experiment the survival rate of probiotic bacteria L. brevis PCM 2570 was increased 1.2-fold to 6.96-fold due to the presence of Fe3O4 magnetic nanoparticles, as compared to the control. The minimum concentration of nanoparticles with a positive effect was 8 mg/ml, but the optimum concentration was 20 mg/ml.

Acid Fermentation

Food waste has a great potential for resource recovery due to its huge yield and high organic content. Oriented fermentation is a promising method with strong application prospects due to high efficiency, strong robustness, and high-value products. Different fermentation types lead to different products, which can be shifted by adjusting fermentation conditions such as inoculum, pH, oxidation-reduction potential (ORP), organic loading rate (OLR), and nutrients. Compared with other types, lactic acid fermentation has the lowest reliance on artificial intervention. Lactic acid and volatile fatty acids are the common products, and high yield and high purity are the main targets of food waste fermentation. In addition to operational parameters, reactors and processes should be paid more attention to for industrial application. Currently, continuously stirred tank reactors and one-stage processes are used principally for scale-up continuous fermentation of food waste. Electro-fermentation and iron-based or carbon-based additives can improve food waste fermentation, but their mechanisms and application need further investigation. After fermentation, the recovery of target products is a key problem due to the lack of green and economic methods. Precipitation, distillation, extraction, adsorption, and membrane separation can be considered, but the recovery step is still the most expensive in the entire treatment chain. It is expected to develop more efficient fermentation processes and recovery strategies based on food waste composition and market demand.

The objective of this study was to investigate alginate microencapsulated lactic acid bacteria (LAB) fermentation quality of radish kimchi sample and its potential survivability in different acidic and alkaline environments. Initially, we isolated 45 LAB strains. One of them showed fast growth pattern with potential probiotic and antifungal activities against Aspergillus flavus with a zone of inhibition calculated with 10, 8, 4mm for the 4th, 5th, and 6th day, respectively. Therefore, this strain (KCC-42) was chosen for microencapsulation with alginate biopolymer. It showed potential survivability in in-vitro simulated gastrointestinal fluid and radish kimchi fermentation medium. The survival rate of this free and encapsulated LAB KCC-42 was 6.85 × 105 and 7.48× 105 CFU/ml, respectively; the viability count was significantly higher than nonencapsulated LAB in simulated gastrointestinal juices (acid, bile, and pancreatin) and under radish kimchi fermentation environment. Kimchi sample added with this encapsulated LAB showed increased production of organic acids compared to nonencapsulated LAB sample. Also, the organic acids such as lactic acid, acetic acid, propionic acid, and succinic acid production in fermented kimchi were measured 59mM, 26mM, 14mM, and 0.6mM of g/DW, respectively. The production of metabolites such as lactic acid, acetic acid, and succinic acid and the bacteria population was high in microencapsulated LAB samples compared with free bacteria added kimchi sample. Results of this study indicate that microencapsulated LAB KCC-42 might be a useful strategy to develop products for food and healthcare industries.
