Abstract:

One hundred forty-one lactobacilli strains isolated from natural whey starter cultures and ripened Grana Padano and Parmigiano Reggiano cheeses were tested for their susceptibility to 13 antibiotics, in particular, penicillin G, ampicillin, amoxicillin, oxacillin, cephalotin, cefuroxime, vancomycin, gentamicin, tetracycline, erythromycin, clindamycin, co-trimoxazole, and nitrofurantoin. The strains belonged to the species Lactobacillus helveticus, L. delbrueckii subsp. lactis, L. rhamnosus, and L. casei.

Lactococcus lactis is a lactic acid bacterium (LAB), generally recognized as safe, and has been widely used in the food industry, especially in fermented dairy products. Numerous studies have evaluated the technological and probiotic properties of lactococci; however, few studies have reported the probiotic characteristics of L. lactis strains isolated from dairy products. In this work, probiotic potential, including survival in simulated gastric juice, tolerance to bile salts, hydrophobicity, and auto- and co-aggregation, was evaluated in L. lactis strains from natural whey starter cultures.

Abstract:

The purpose of the work was to investigate the influence of different lactose hydrolysis processes, the contribution of the enzyme and the milk type on the characteristics of the obtained lactose-free yogurt. The analysis was performed on non-hydrolyzed yogurt (control sample), the pre-hydrolyzed yogurt (that was hydrolyzed before fermentation), and the co-hydrolyzed yogurt (concurrent addition of β-galactosidase and starter culture). According to the obtained results, at the end of the fermentation time, an advanced hydrolysis degree was reached (over 80%) both for yogurt samples obtained fro

Abstract Dadih is a typical Minangkabau dairy product which is produced through the application of the natural fermentation of buffalo milk in a bamboo tube under conditions facultative anaerobic due to the presence of banana leaves as the packaging cover. This review aims to examine nutritional characteristics and microbiological aspects of Dadih as a traditional fermented food product from West Sumatra, and the challenges and development of Dadih products for application in the food industry. Microbes that play a dominant role in Dadih fermentation are Streptococcus thermophilus, Lactobacill

Abstract:

São Jorge cheese is an iconic product of the Azores, produced from raw cow’s milk and natural whey starter (NWS). Although it is produced according to Protected Designation of Origin (PDO) specifications, the granting of the PDO label depends crucially on sensory evaluation by trained tasters. The aim of this work was to characterize the bacterial diversity of this cheese using next-generation sequencing (NGS) and to identify the specific microbiota that contributes most to its uniqueness as a PDO by distinguishing the bacterial communities of PDO and non-PDO cheeses.

Natural and defrosted goat’s milk, semi-hard cheeses with a low temperature of the second heating were used as objects of research. Studies of defrosted goat’s milk were carried out after 6±1 days of its storage at a temperature of minus 18°C and subsequent defrosting at a temperature of 37±2°C for 60 minutes; natural goat’s milk — after storage for 24±12 hours at a temperature of 4±2°C.

Abstract Whey from previous production is often used as a natural starter in the technology of traditional cheeses, including bryndza-cheese in Slovakia. Therefore, studying its bacterial community and isolating new potential natural starters is important for improving the characterisitics of final product. Composition of bacterial consortia of fresh and fermented whey in the production of raw ewes´ milk-based bryndza-cheese from 8 small or medium-sized producers was analysed.

Abstract:

ABSTRACT Preservation of cheese microbiota biodiversity is central to the sensory quality of traditional and PDO cheeses. Lyophilized commercial selected starters, being advantageous in terms of cells concentration, are supplanting natural cultures causing important loss of microbial biodiversity in the dairy environment. Biodiversity could be recovered using natural starter cultures, however their cells concentration after propagation is lower than the commercial ones.

Bacterial and phage screening was carried out on cooked not acidified whey and NWS samples isolated from six dairy factories, for 4 consecutive days in four different months. By means of a combined approach, using plate counts, bacterial isolation, and metataxonomic analysis Lactobacillus helveticus was found occurring as the dominant species in NWS cultures and Levilactobacillus brevis as codominant

AbstractNatural whey starters (NWS) are undefined bacterial communities produced daily from whey of the previous cheese-making round, by application of high temperature. As a result, in any dairy plant, NWS are continuously evolving, undefined mixtures of several strains and/or species of lactic acid bacteria, whose composition and performance strongly depend on the selective pressure acting during incubation. While NWS is critical to assure consistency to cheese-making process, little is known about the composition, functional features, and plant-to-plant fluctuations. Here, we integrated 16S
