Exploiting light to drive redox reactions is currently a hot topic since considered as an environmentally friendly source of energy. Consequently, cyanobacteria, which can use e.g., for generating NADPH, are in the focus research. Previously, it has been shown that various heterologous enzymes could be expressed these microorganisms. Here we demonstrated successful inducer-free expression α-ket...

Lactic acid bacteria (LAB) with potential for the development of multi-product processes are necessary valorization side streams obtained during biotechnological production lactic (LA). In this study, 14 LAB strains isolated from pineapple agro-industrial residues in Costa Rica were cultivated microplates, and six highest growth selected fermentation microbioreactors to evaluate LA acetic acid,...

Bile salt hydrolases (BSH) results in microbes releasing enzymes conferring physiological functions for both the producing organisms and host subsequently lower serum cholesterol. In recent years, these attributes have generated interest towards screening of lactic acid bacteria (LAB) functional food production. this present study, lactobacilli (n=34) (13 L. casei, 6 paracasei, 11 brevis, 3 pen...

A resting cell system was developed for bacteriocin Lac-B23 production from Lactobacillus paracasei J23. The resting cell medium contained (g/L): Glucose 20, Sodium acetate 5.0, MnSO4 0.25 MgSO4 0.5, Ammoniumhydrogencitrate 1.0, KH2PO4 1.0. The resting cell incubation time and temperature were 20 h and 37 °C and the effects of exogenous factors, including amino acids, glycerol, pyruvic acid, an...

Spray drying of skim milk was evaluated as a means of preserving Lactobacillus paracasei NFBC 338 and Lactobacillus salivarius UCC 118, which are human-derived strains with probiotic potential. Our initial experiments revealed that NFBC 338 is considerably more heat resistant in 20% (wt/vol) skim milk than UCC 118 is; the comparable decimal reduction times were 11.1 and 1.1 min, respectively, a...

Objective. To investigate the effects of Lactobacillus acidophilus NCFM / Bifidobacterium lactis BL-04 / fructooligosaccharide and Lactobacillus plantarum LP01/ Lactobacillus paracasei LPC00 / fructo-oligosaccharide preparations in the routine clinical management of seasonal allergic rhinitis (SAR) and perennial allergic rhinitis (PAR), respectively. Materials and Methods. Seventy-six and fifty...

Background: Lactic acid bacteria (LAB) are normal flora of the mouth, intestines and the female genital tract. They are also frequently found in meat, vegetables, and dairy products. Most of probiotic bacteria belong to the LAB group. Some probiotic LAB are useful in prevention and treatment of diarrheal diseases. The aim of this study was to investigate the antimicrobial properties of LAB isol...

In this research, the survival of probiotic microorganisms in yogurts stored at room temperature (cold chain interruption conditions) was studied. Milk inoculated with yogurt bacteria (mixed culture of Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus) and a single probiotic culture (L. acidophilus LA-5 or Bifidobacterium lactis Bb-12 or L. rhamnosus HN001 or L. paracasei...

The draft genome sequence of Lactobacillus paracasei DmW181, an anaerobic bacterium isolate from wild Drosophila flies, is reported here. Strain DmW181 possesses genes for sialic acid and mannose metabolism. The assembled genome is 3,201,429 bp, with 3,454 predicted genes.
