Abstract
Several strategies, programs and policies have long been developed and implemented to alleviate child malnutrition in sub-Saharan African countries. However, stunting and wasting still persist at an alarming rate, suggesting that alternative strategies are needed to induce faster progress toward the 2030 SDGs targets of reducing malnutrition. Gut microbiota-directed intervention is now being recognized as an unconventional powerful approach to mitigate malnutrition and improve overall child health. In an African setting, manufactured probiotic and synbiotic foods or supplements may not be successful owing to the non-affordability and high attachment of African populations to their food tradition. This review analyses the potential of indigenous fermented cereal-based products including porridges, doughs, beverages, bread- and yoghurt-like products, to be used as microbiota-directed foods for over 6 months children. The discussion includes relevant strategies to effectively enhance the beneficial effects of these products on gut microbiota composition for improved child health and nutrition in sub-Saharan Africa. Characterization of probiotic features and general safety of food processing in sub-Saharan Africa as well as randomized clinical studies are still lacking to fully ascertain the health effects and suitability of these fermented foods in preventing and treating child malnutrition and diarrhea.

Abstract
Vitamin enrichment in fermented dairy products through the intervention of vitamin-producing probiotic strains during fermentation is a novel approach in the field of probioceuticals. In this study, riboflavin-enriched yogurt-based fermented milk was prepared by mixing 1% (v/v) riboflavin-producing strain [1.2 × 108 CFU/mL of Lactiplantibacillus plantarum MTCC 25432 or L. plantarum MTCC 25433 or L. plantarum MTCC 25434] with 2% (v/v) traditional yogurt cultures [Streptococcus thermophilus NCDC 295 and L. delbrueckii subsp. bulgaricus NCDC 293; each of 1.3 × 107 CFU/mL]. The yogurt-based fermented milk prepared with traditional yogurt cultures (2%, v/v) was served as a control. The prepared yogurt-based fermented milk samples were analyzed and compared for riboflavin content, antimicrobial activity, physicochemical, and functional properties. As a result, the yogurt-based fermented milk prepared with L. plantarum MTCC 25432 produced a significantly higher amount of riboflavin (2.49 mg/L) as compared with MTCC 25433 (2.33 mg/L), MTCC 25434 (2.14 mg/L), and control (1.70 mg/L). The probiotic supplementation to yogurt cultures maintained the pH and titratable acidity in the range of 4.1-4.4 and 1.0-1.05% (lactic acid/100 mL), as recommended by Indian yogurt standards. The rheological, texture, and antimicrobial properties of yogurt-based fermented milk were enhanced with the addition of riboflavin-producing probiotic strains. Moreover, all yogurt-based fermented milk samples prepared in this study were acceptable as per the sensory evolution scores. In conclusion, the use of riboflavin-producing L. plantarum strains along with standard yogurt cultures could be the best approach to enhancing riboflavin content in yogurt-based fermented milk and fulfilling the daily riboflavin requirement in humans.

Abstract
Riboflavin (Vitamin B2) is an essential vitamin and a microbial metabolite produced by some lactic acid bacteria (LAB). This investigation aims to study the overproduction of riboflavin in selected Lactiplantibacillus plantarum strain by using the one factor at a time (OFAT) tool coupled with the Fuzzy Inference System (FIS) and its validation through fermentative production in semi-defined media. Out of three Lactiplantibacillus strains used in this study, the maximum riboflavin producing strain was selected based on its ability to grow and produce higher levels of riboflavin. In results, Lactiplantibacillus plantarum strain MTCC 25432 was able to produce 346 µg/L riboflavin in riboflavin deficient assay medium and was investigated further. By using the OFAT-fuzzy FIS system, casamino acid in the range of 5-20 g/L, GTP 0.01-0.04 g/L, sodium acetate 5-15 g/L, and glycine 5-15 g/L were used to predict their effect on riboflavin production. The conditions optimized with modeling showed a 24% increment in riboflavin production (429 µg/L) by Lactiplantibacillus plantarum MTCC 25432 vis-a-vis the unoptimized counterpart (346 µg/L). In conclusion, an FIS-based predictive model was effectively implemented to estimate the riboflavin within an acceptable limit of 3.4%. Riboflavin production enhancing effects observed with various levels of sodium acetate, casamino acid, and GTP could be useful to re-design matrices for riboflavin production.

Abstract
Micronutrient deficiency still occurs in sub-Saharan Africa (SSA) despite the availability of several food resources, particularly fermented foods and vegetables, with high nutritional potential. Fermentation enhances the quality of food in several aspects. Organoleptically, certain taste, aroma, and textures are developed. Health and safety are improved by inhibiting the growth of several foodborne pathogens and removing harmful toxic compounds. Furthermore, nutrition is enhanced by improving micronutrient contents and bioavailability from the food, especially vitamin B content. However, during processing and before final consumption, many fermented foods are heat treated (drying, pasteurization, cooking, etc.) to make the food digestible and safe for consumption. Heat treatment improves the bioavailability of B-vitamins in some foods. In other foods, heating decreases the nutritional value because some B-vitamins are degraded. In SSA, cooked starchy foods are often associated with vegetables in household meals. This paper reviews studies that have focused fermented starchy foods and vegetable foods in SSA with the potential to provide B-vitamins to consumers. The review also describes the process of the preparation of these foods for final consumption, and techniques that can prevent or lessen B-vitamin loss, or enrich B-vitamins prior to consumption.

Abstract
Microencapsulation is an optimistic method for the delivery of live microbial cells through different food products. In this study, riboflavin-producing probiotic strain Lactiplantibacillus plantarum MTCC 25,432 was encapsulated using a spray drying technique with different wall materials including Inulin, maltodextrin (MD), and MD + Inulin (1:1). The obtained spray dried powder was investigated for probiotic viability, encapsulation efficiency, particle size, water activity, moisture content, hygroscopicity, bulk and tapped densities, storage stabilities, Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). Besides this, the viability of the free and encapsulated probiotic cells was tested under simulated gastric and intestinal fluid conditions. In the results, microcapsules produced with the combination of MD + Inulin showed higher dry powder yield (36.5%) and viability of L. plantarum MTCC 25,432 (7.4 log CFU / g) as compared with individual coating materials. Further characterization revealed that MD + Inulin microcapsules are spherical (3.50 ± 1.61 μm in diameter) in shape with concavities, showed the highest encapsulation efficiency (82%), low water activity (0.307), moisture content (3.67%) and good survival ability at low pH (pH 2.0 and 3.0), high bile salt concentrations (1.0% and 2.0%), and long storage conditions. No differences in FTIR spectra were observed among the tested samples. However, TGA showed enhanced thermal stability of probiotic-loaded microcapsules when MD + Inulin was used together. In conclusion, MD + Inulin could be a potential encapsulation material for riboflavin-producing probiotic bacteria L. plantarum MTCC 25,432.

Abstract
The gut microbiota of soymilk intervention is beneficial to maintaining human health. Bacillus subtilis fermented soymilk has brought much interest, due to its richness of thrombolytic nattokinase and the strain of potential probiotic properties. In this study, soymilk was fermented by B. subtilis BSNK-5, and the BSNK-5-fermented soymilk (SMF) on the production of short chain fatty acids (SCFAs) and the regulation of fecal microbiota was initially evaluated by in vitro fecal fermentation. SMF supplementation obviously increased the levels of SCFAs from 32.23 mM to 49.10 mM, especially acetic acid, propionic acid, and isobutyric acid. Additionally, SMF changed the composition and microbial diversity of gut microbiota. After 24 h of anaerobic incubation in vitro, SMF decreased the Firmicutes/Bacteroidota ratio favoring weight loss, increased Lachnospiraceae_UCG-004 and the other beneficial bacteria producing SCFAs, as well as suppressing pathogenic Streptococcus genus. These results revealed the potential use of BSNK-5-fermented soymilk as a potential candidate to promote gut health.

Abstract
In the present study, Lactobacillus plantarum-HDS27 strain isolated from bovine milk was used for the enhanced production of riboflavin. Production medium was optimized by one factor at a time with different parameters. Statistical optimization by Response surface methodology (RSM), central composite design was used to optimize variables such as pH, temperature, glucose, and yeast extract. The present study reveals the maximum riboflavin production by one factor at a time was obtained under the culture conditions; glucose, yeast extract, pH 6, the temperature at 40°C, and 3% of inoculum size. In RSM, analysis of variance for the responses was calculated. Among the tested variables, pH, yeast extract, and temperature showed significant impact on riboflavin production. Maximum amount of yeast extract in production medium resulted in increased riboflavin production. The riboflavin production after 24 h with the optimal condition was found to be 12.33 mg/L. It was found proximate to the expected value (12.29 mg/L) achieved by the RSM model. The yield of riboflavin was increased to 3.66-fold after 24 h with the optimized parameters. The current research, emphasizes that the Lactobacillus plantarum–HDS27 could be an excellent strain for the large-scale industrial production of riboflavin.

Abstract
The present study was designed to bio-fortify the soymilk (per se a B12-free plant food matrix). The PCR-based screening characterized the human fecal samples (4 out of 15 tested) and correspondingly identified novel lactobacilli isolates (n = 4) for their B12 production potential and rest (n = 62) as negative for this attribute. Further, 3 out of the 4 selected strains showed ability for extracellular vitamin production. The most prolific strain, Lactobacillus reuteri F2, secreted B12 (132.2 ± 1.9 μg/L) in cobalamin-free-medium with the highest ratio ever reported (0.97:1.00; extra-: intra-cellular). In next stage, the soymilk was biofortified in situ with B12 during un-optimized (2.8 ± 0.3 μg/L) and optimized (156.2 ± 3.6 μg/L) fermentations with a ∼54-fold increase at Artificial Neuro Fuzzy Inference System based R value of >0.99. The added-nutrients, temperature and initial-pH were observed to be the most important fermentation variables for maximal B12 biofortification. We report Lactobacillus rhamnosus F5 as the first B12 producing (101.7 ± 3.4 μg/L) strain from this species. The cyanocobalamin was extracted, purified and separated on UFLC as nutritionally-relevant B12. Besides, the vitamin was bioavailable in an auxotrophic-mutant. The lactobacilli fermentation is suggested, therefore, as an effective approach for B12 biofortification of soymilk. PCR-based real-time screening of human fecal samples for the presence of B12-related cbiK gene. Novel report of B12 production in Lactobacillus rhamnosus species (strain F5). A rare B12-producing phenotype of Lactobacillus reuteri F2 with highest ever ratio of extracellular vs total B12 (0.95:1.0). Sequential optimization (OFAT .→ GSD → ANFIS) enhanced post-fermentation soymilk B12 levels by 54-folds. One serving size (100 mL) of L. reuteri F2-biofortified fermented soymilk offered 6.5-fold higher B12 than human RDA. The produced B12 form is nutritionally-relevant and biologically active for humans.

Abstract
Preparation of soymilk-based product with probiotics is reasonably a novel approach in the field of fermented functional foods. The aim of this study was to develop riboflavin enriched fermented soy curds with either or combination of the two riboflavin producing probiotic strains of Lactobacillus plantarum i.e., MTCC 25432 (BBC32B) and MTCC 25433 (BBC33), and to compare the technological and functional properties of its developed products. Acidification rate and lactic acid production were enhanced with L. plantarum and its combination in a shorter time to reach pH 4.7. Hardness and cohesiveness were significantly (p < 0.05) higher for fermented soymilk by co-culture of L. plantarum followed by individual strains. Similarly, higher G′ (6.25 × 102 Pa), G” (2.30 × 103 Pa) and G* (8.00 × 102 Pa) values observed for the combination of both L. plantarum strains showed that the gel formed was firmer and had solid character. The riboflavin content of product developed with a combination of test cultures was significantly higher (342.11 µg/L) than individual cultures and control. The final product had a higher probiotic count (more than 9 log cfu/mL), which is also required for functional food containing probiotics.

Abstract
Lactic acid bacteria (LAB) are known for their probiotic properties, but only a few strains produce riboflavin. We evaluated the probiotic properties of four riboflavin-producing strains of Lactobacillus plantarum (BBC33, BBC32A, BIF43, and BBC32B) by using in vitro assessment and carried out multivariate principal component analysis (PCA) to select the best strain. Safety, antioxidant, and exopolysaccharide-producing properties were also studied. Lact. plantarum BBC33 showed better probiotic potential, followed by strain BIF43. Lact. plantarum BBC32A degraded mucin and excluded as a potential probiotic candidate. Lact. plantarum BIF43, BBC33, and BBC32A tolerated simulated gastrointestinal conditions and their overnight cell-free culture supernatants (CFSs, pH 4.0-4.3) inhibited the growth of Escherichia coli AF10, Salmonella Typhi MTCC98, Bacillus cereus NCDC250, and Pseudomonas aeruginosa NCDC105. Lact. plantarum BIF43 and BBC33 did not degrade mucin, adhered to human epithelial colorectal adenocarcinoma Caco-2 cells (22-25%), and aggregated with indicators (30-50%). Moreover, both were non-hemolytic and sensitive to most antibiotics tested. Of the two selected strains, BIF43 showed better exopolysaccharides (EPS) producing phenotype. The CFSs of all strains showed high (85-93%) 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity. PCA confirmed the results obtained from in vitro probiotic experiments and supported the selection of Lact. plantarum BIF33 and BBC43, as potential probiotics.
