This study evaluated the effects of prebiotics on fermentation profile and growth of Lactobacillus acidophilus, Lactobacillus bulgaricus, Lactobacillus rhamnosus, and Bifidobacterium lactis in co-cultures with Streptococcus thermophilus. Acidification rate and viability were positively influenced by the co-culture with B. lactis and by both inulin or oligofructose in low fat milk.

Abundant biomass, including industrial waste streams and second-generation (2G) and third-generation (3G) feedstocks, offers significant potential for sustainable bioconversion, nevertheless challenges such as fermentation inhibitors, CO losses and substrate selectivity of traditional microbial hosts hinder process efficiency. In this study, we address these challenges by exploring acetogenic bacteria as alternative microbial hosts. Using a newly established high-throughput method, acetogens were evaluated for their capacity to hydrolyse and metabolise variety of substrates derived from 2G and 3G feedstocks and industrial waste streams.

Background: 2'-Fucosyllactose (2'-FL) is a predominant human milk oligosaccharide that significantly enhances infant nutrition and immune health. This study addresses the need for a safe and economical production of 2'-FL by employing Generally Recognized As Safe (GRAS) microbial strain, Priestia megaterium ATCC 14581. This strain was chosen for its robust growth and established safety profile and attributing suitable for industrial-scale production.

Cassava (Manihot esculenta Crantz) is a crucial crop in tropics and subtropics, primarily cultivated for its tuber. However, its foliage is rich in protein and can supply essential elements for ruminants. The objective of this study was to evaluate the phytochemical compounds by Gas chromatography-MS (GC-MS) and the main phenolic by High Pressure Liquid Chromatography (HPLC) present in cassava foliage, along with the fermentation pattern using a semi-automated gas production (GP) system.

In the current study, the effects of fermentation by Lactobacillus acidophilus, Levilactobacillus brevis or Lactiplantibacillus plantarum (La/Lb/Lp, 1-2.5%) and incubation (30/37 °C, C1/C2) of red beetroot juice on the profile of betalains and polyphenols (UHPLC-DAD-MS), and antioxidant capacity using photochemiluminescence (PCL) and spectrophotometric assays (DPPH/ABTS) was investigated. Additionally, anti-glycaemic (anti-AGEs) and anticholinergic (anti-AChE) potential in vitro was analysed.

This study aimed to conduct a preliminary investigation in eight Sardinian fermented sausage (SFS) production plants to acquire knowledge about the differences in the applied technological process and their influence on the safety and sensory characteristics of the finished product. Two audits were conducted in each plant to evaluate structural characteristics and process technologies; 72 samples of SFS at the end of seasoning and 48 environmental samples were analyzed. , spp.
