Lactic acid (LA) is one of the primary metabolites that is considered to be a natural product derived from microorganisms such as Lactic Acid Bacteria (LAB). The most prominent LA- producing LAB is the genus of Lactobacillus spp. and is found in almost all dairy products along with non-dairy food products. The application of LA can be found in various sectors including food, fermentation, pharmaceuticals, and chemical industries. LAB have lots of perspective in the production of organic acids as well as complex compounds that find potential application in food products such as yoghurt, cheese, buttermilk in addition to therapeutics uses such as probiotics that help in preventing gastrointestinal infections; improve pathogen protection; and alter host immunological responses. Moreover, fermentation with LAB also facilitates efficient nutrient quality and provides an effective method of food preservation. The present study provides an overview of the potential application of LA produced by Lactobacillus spp. in different sectors.

Safety And Stability

Probiotics are microorganisms that confer health benefits to host. Well-known examples include Bifidobacterium and Lactobacillus species. In recent years, interest in promoting our health with probiotics has grown as life expectancy and health awareness has increased. However, some concerns for safety and stability exist for these live organisms. Thus, “postbiotics” and “paraprobiotics,” non-viable heat-killed microbial cells or cell fractions that retain health benefits, are increasingly favored. Unfortunately, little information on clinical efficacy and mechanisms of action is available compared with many available probiotics. Lacticaseibacillus (previous name Lactobacillus) paracasei MCC1849 is a commonly used lactic acid bacterial strain in Japan that displays immuno-modulatory effects in humans in non-viable heat-killed form. This review discusses health benefits of heat-killed L. paracasei MCC1849 immune modulation and offers a theoretical basis for its mechanisms of action. We also discuss the feasibility of using heat-killed probiotics for application in food products.

Cassava is a drought-tolerant, crop grown in tropical and subtropical areas. For decades the communities of Africa have developed their process to ferment and use cassava. Ikivunde, Inyange, kivunde, Mokopa, Chikwangue, Meduame-M-bong, Cossette, Gari, Attiéké, and Agbelima are the main indigenous fermented cassava based food products from east, west and central Africa respectively. Lactic acid bacteria, yeast, and molds are the main microorganism involve in the fermentation of cassava-based food products and contribute to the production of biochemical compounds such as folates, several organic acids, volatiles organics compound, and others compounds. Role of different microorganisms in food preservation, increase in protein content, aroma, flavor enhancement, decreases in anti-nutrients, and cyanogen reduction as the elevated impact of the fermentation process.

Traditional manufacture of bread from maize has been noted to play important roles from both economic and social standpoints; however, enforcement of increasingly strict hygiene standards requires thorough knowledge of the adventitious microbiota of the departing dough. To this goal, sourdough as well as maize and rye flours from several geographic locations and in two different periods within the agricultural year were assayed for their microbiota in sequential steps of quantification and identification. More than 400 strains were isolated and taxonomic differentiation between them was via Biomerieux API galleries (375 of which were successfully identified) following preliminary biochemical and morphological screening. The dominant groups were yeasts and lactic acid bacteria (LAB). The most frequently isolated yeasts were Saccharomyces cerevisiae and Candida pelliculosa. The most frequently isolated LAB were (heterofermentative) Leuconostoc spp. and (homo-fermentative) Lactobacillus spp.; L. brevis, L. curvatus, and L. lactis ssp. lactis were the dominant species for the Lactobacillus genera; Lactococcus lactis ssp. lactis for lactococci; Enterococcus casseliflavus, E. durans, and E. faecium for enterococci; and Streptococcus constellantus and S. equinus for streptococci.

Skimmed Milk

There are three main reasons for using lactic acid bacteria (LAB) as starter cultures in industrial food fermentation processes: food preservation due to lactic acid production; flavour formation due to a range of organic molecules derived from sugar, lipid and protein catabolism; and probiotic properties attributed to some strains of LAB, mainly of lactobacilli. The aim of this study was to identify some genes involved in lactose metabolism of the probiotic Lactobacillus delbrueckii UFV H2b20, and analyse its organic acid production during growth in skimmed milk. The following genes were identified, encoding the respective enzymes: ldh – lactate dehydrogenase, adhE – Ldb1707 acetaldehyde dehydrogenase, and ccpA-pepR1 – catabolite control protein A. It was observed that L. delbrueckii UFV H2b20 cultivated in different media has the unexpected ability to catabolyse galactose, and to produce high amounts of succinic acid, which was absent in the beginning, raising doubts about the subspecies in question. The phylogenetic analyses showed that this strain can be compared physiologically to L. delbrueckii subsp. bulgaricus and L. delbrueckii subsp. lactis, which are able to degrade lactose and can grow in milk. L. delbrueckii UFV H2b20 sequences have grouped with L. delbrueckii subsp. bulgaricus ATCC 11842 and L. delbrueckii subsp. bulgaricus ATCC BAA-365, strengthening the classification of this probiotic strain in the NCFM group proposed by a previous study. Additionally, L. delbrueckii UFV H2b20 presented an evolutionary pattern closer to that of probiotic Lactobacillus acidophilus NCFM, corroborating the suggestion that this strain might be considered as a new and unusual subspecies among L. delbrueckii subspecies, the first one identified as a probiotic. In addition, its unusual ability to metabolise galactose, which was significantly consumed in the fermentation medium, might be exploited to produce low-browning probiotic Mozzarella cheeses, a desirable property for pizza cheeses.

Abstract This study aimed to evaluate the effect of diets containing increasing levels of citrus pulp on the physicochemical and microbiological characteristics of horses feces. Five mares, at an average age of 3.5 years old and body weight of 492 ± 44.5 kg were arranged in a 5 x 5 Latin Square. The experimental diet consisted of 60% coast-cross hay and 40 % of concentrate with increasing levels of citrus pulp (0, 7, 14, 21, and 28 %). To determine the fecal pH, samples were collected directly from the floor, immediately after defecation, in the first feces of the day at 07:00 a.m., and color and fecal consistency were evaluated. For microbiological analysis, an aliquot was reserved in plastic bags, frozen, and sent to the microbiological laboratory for further analysis. Lactic acid bacteria were counted for Lactobacillus spp. and Streptococcus spp. from fecal samples under anaerobic conditions. The diet produced differences (P<0.05) in feces consistency: 98% of the animals had normal and firm stools, while 2% were loose ruminant-type feces. We observed no difference (P<0.05) for color, verifying 100% of the animals of greenish feces, normal for equines. There was no effect (P>0.05) on pH and on the number of Lactobacillus spp. and Streptococcus spp. The inclusion of up to 28% citrus pulp concentrates for horses did not promote change in the physicochemical characteristics and on the population of lactic acid-producing bacteria in feces.
