Special Issue Information

Dear Colleagues,

Lactic acid bacteria are widely used in the production of fermented foods. These bacteria are responsible for the conversion of sugars into lactic acid, which provides fermented foods with their characteristic tangy flavor and preserves them from spoilage. Fermented foods made with lactic acid bacteria include yogurt, kefir, sauerkraut, kimchi, and many others. These foods are not only delicious but also have health benefits due to their probiotic content. Lactic acid bacteria have also been used in the production of biopreservatives and bioactive compounds that have potential applications in the food industry. Overall, the application of lactic acid bacteria in fermented food has been a significant contribution to the food industry and human health.

Recently, there has been a renewed interest in the fermentation of kefir grains using fruit-based substrates, such as coconut water. Kefir grains contain a mixture of lactic acid bacteria (LAB), acetic acid bacteria (AAB), and yeast, which have important probiotic capacity and play a vital role in improving the nutritional and functional properties of the new product being developed. The principal objective of this study was to determine the functional properties of the microorganisms identified and characterized from kefir, CWK, and sourdough fermented with coconut water kefir (CWKS), such as Limosilactobacillus fermentum, Lactiplantibacillus plantarum, L. fusant, L. reuteri, L. kunkeei, Acetobacter aceti, A. lovaniensis, A. pasteurianus, Candida kefyr, Rhodotorula mucilaginosa, Saccharomyces cerevisiae, C. guilliermondii, and C. colliculosa. In addition to identifying functional properties, such as glutamic acid production, phytase production, phytic acid degradation, and exopolysaccharide production, from this study, it was found that significantly high quantities of glutamic acid, exopolysaccharide, and phytase enzyme were detected in two LAB isolates, Limosilactobacillus fermentum and Lactiplantibacillus plantarum.

This study aimed to explore the fermentative performance of nine lactic acid bacterial strains with probiotic potential during sorghum fermentation. The strain’s attributes including proliferation counts, pH levels, production of organic acid antibacterial activity, and their ability to break down starch were evaluated during the fermentation period in the presence and absence of glucose as a carbon source. In addition, the inhibitory activity of these potential probiotic strains against pathogenic bacteria (Salmonella typhimurium, Escherichia coli, and Staphylococcus aureus) was examined through a co-culturing technique. The results demonstrated that all 4 Lactobacillus strains exhibited robust growth in both glucose and glucose-free fermentation experiments. Glucose supplementation significantly enhanced lactic acid yield which ranged from 0.19 to 0.44% compared to fermentation without glucose which ranged from 0.04 to 0.29%. The selected Lactobacillus strains effectively lowered the media pH below 4.0 after 24 h, producing substantial lactic acid. Notably, in the absence of glucose, only Lb. helveticus D7 and Lb. amylolyticus D12 achieved pH levels below 4 after 8 h, producing the highest lactic acid amounts of 0.27 and 0.29% after 24 h, respectively. Amylase activity was detected on two strains, D7 and D12. Furthermore, most of the tested Lactobacillus strains demonstrated complete inhibition (6 log to 0 Log CFU/mL) of pathogen growth after 24 h of co-culturing, suggesting their potential for enhancing the safety quality of sorghum-based fermented products.

Ethiopia has one of the highest levels of malnourished lactating mothers in sub-Saharan Africa. However, traditionally, different communities prepare foods solely for lactating mothers. For example, “Shameta” is one of the cereal-based fermented cultural foods exclusively produced for lactating mothers with the perception that it would support the health, increase the strength, and promote the recovery process of mothers after childbirth. This study investigated the effects of the fermentation time and blending ratio on the nutritional quality of “Shameta”. Three levels of blending ratio of ingredients (maize–barley–fava bean) and three levels of fermentation times were laid down in a completely randomized design (CRD). The study showed that lactic acid bacteria was the dominant group, followed by yeasts. Notably, the ingredient formulation ratio of Maize–barley–fava bean (81:5:5) had the highest LAB dominance with the highest crude fat (13.23 g/100g) content in all fermentation times (8, 10, and 12 days). However, the highest crude protein (16.56 g/100g) and mineral contents were observed in a ratio mix of 66:10:15 fermented for 12 days. The results of this study indicate that the nutritional quality of culturally prepared Shameta can be improved by optimizing the fermentation time and ingredient compositions for fast recovery, increased strength, and improved health of lactating mothers.

Due to industrial development, heavy metal pollution has become a severe global health hazard. The bioadsorption method represented by the adsorption of lactic acid bacteria (LAB) has been widely employed. The purpose of this study is to screen LAB strains that can remove cadmium, lead, and chromium. Through the heavy metal resistance tests, four strains with significant growth inhibition rate were identified. After 16S rDNA sequencing, these resistant strains were identified by Lactobacillus helveticus KD-3 (Cd2+ removal rate 37.54 ± 0.85%), Limosilactobacillus fermentum B27 (Pb2+ removal rate 69.41 ± 0.19%), Lacticaseibacillus rhamnosus 7469 (Cr6+ removal rate 71.13 ± 0.97%), and Lb. helveticus K5. Three encoding genes were identified in our screen strains, namely resistance gene czcD, chromium resistance gene chrA, and lead resistance gene pbrT. L.helveticus KD-3 exhibited the best comprehensive performance. Given the diverse types of heavy metal pollution at present, the current research mainly focuses on the removal of a single heavy metal by one strain. The four strains enrich the absorption resources of LAB for heavy metals, paving a new way for the biosorption of various heavy metals in food by LABs. Full article

This study investigated the synergistic effects of combining Saccharomyces cerevisiae and Oenococcus oeni during the alcoholic fermentation of a low-acidity cider. The initial population of indigenous wild lactic acid bacteria (LAB) in the apple must was 104 CFU/mL. Alcoholic fermentations were carried out without (Cider I) and with (Cider II) the O. oeni inoculation at 105 CFU/mL. As S. cerevisiae grows, a declining trend was observed in indigenous and inoculated LAB populations. While the wild LAB exhibited higher sensitivity than O. oeni, they were not eliminated during alcoholic fermentation. The addition of O. oeni impacted the growth and metabolic activity of S. cerevisiae. The bioconversion of malic acid into lactic acid predominantly occurred during the growth phase (43–66%) and stationary phase (4–27%). The resurgence of O. oeni following alcoholic fermentation significantly impacted the production of volatile compounds. After 20 days of fermentation, Cider II displayed a twofold increase in these compounds, resulting in a more favorable sensory profile according to evaluators. Consequently, malolactic fermentation (MLF) coincided with alcoholic fermentation, leading to a reduction in malic acid content. Furthermore, post alcoholic fermentation, MLF positively enhanced the aromatic quality of low-acid cider made from apples with low acidity. Full article
