Lactobacillus plantarum LUHS135 and paracasei LUHS244 as functional starter cultures for the food fermentation industry: Characterisation, mycotoxin-reducing properties, optimisation of biomass growth and sustainable encapsulation by using dairy by-products
Abstract Lactobacillus plantarum LUHS135 and Lactobacillus paracasei LUHS244 from fermented cereals were isolated and their properties (carbohydrate metabolism, gas production, ability to survive at a low pH values, growth performance at different temperatures, antimicrobial properties against Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, Salmonella enterica, Corynebacter spp, Klebsiella pneomoniae, Enterococcus faecalis, Bacillus cereus, Proteus mirabilis, Clostridium spp., Streptococcus spp., resistance to antibiotics, and reducing properties for aflatoxin B1, ochratoxin A, HT-2 toxin, T-2 toxin, zearalenone) were evaluated. Also, the possibilities to use dairy by-produ…
Inhibition of class I histone deacetylase with an apicidin derivative prevents cardiac hypertrophy and failure
AIMS: Recent studies have demonstrated the importance of chromatin remodelling via histone acetylation/deacetylation for the control of cardiac gene expression. Specific histone deacetylases (HDACs) can, in fact, play a positive or negative role in determining cardiac myocyte (CM) size. Here, we report on the effect on hypertrophy development of three inhibitors (HDACi) of class I HDACs. METHODS AND RESULTS: The compounds were first analysed in vitro by scoring hypertrophy, expression of foetal genes, and apoptosis of neonatal rat CMs stimulated with phenylephrine, an alpha1-adrenergic agonist. This initial screening indicated that a truncated derivative of apicidin with class I HDAC specif…
