Antifungal activity of lactic acid bacteria [PDF]

, 2003
Enrichment culture techniques produced more than 1200 isolates of lactic acid bacteria (LAB) that were screened for antifungal activity against the indicator mould Aspergillus fumigatus. Approximately 10% of the LAB were active, but only 4% had medium or

Screening and characterization of Lactobacillus strains producing large amounts of exopolysaccharides [PDF]

, 1998
A total of 182 Lactobacillus strains were screened for production of extracellular polysaccharides (EPS) by a new method: growth in liquid media with high sugar concentrations. Sixty EPS-positive strains were identified; 17 strains produced more than 100

Allosteric regulation of L‐lactate dehydrogenase: Beyond effector‐mediated tetramerization

Protein Science, Volume 34, Issue 7, July 2025.
Abstract The activity of allosterically regulated enzyme is modulated through structural changes induced by effectors. L‐lactate dehydrogenase from Geobacillus stearothermophilus (GsLDH) catalyzes the reversible conversion between pyruvate and lactate using NAD(H), and its activity is known to be activated by fructose 1,6‐bisphosphate (FBP).

Effect of Lactobacillus casei- casei and Lactobacillus reuteri on acrylamide formation in flat bread and Bread roll [PDF]

Journal of Food Science and Technology, 2015
The aim of this study was the evaluation of fermentation by lactic acid bacteria (LAB) contains lactobacillus (L.) casei- casei and L. reuteri on acrylamide formation and physicochemical properties of the Iranian flat bread named, Sangak, and Bread roll. Sangak and Bread roll were made with whole and white wheat flour, respectively.

Characterization and ex vivo modelling of endodontic infections from the Arabian Gulf region

International Endodontic Journal, Volume 58, Issue 7, Page 1091-1108, July 2025.
Abstract Aim The microbiota of endodontic infections in patients from the Arabian Gulf region (AGR) is largely unexplored. While research in different global regions has investigated the microbial composition of such infections, studies using shotgun metagenomic sequencing (SMS) alongside culture‐dependent techniques (CDT) are limited.

The Binding Efficiency and Interaction of Lactobacillus casei Shirota Toward Aflatoxin B1

Frontiers in Microbiology, 2018
The use of probiotic as dietary approach to prevent exposure to food contaminant, aflatoxin B1 (AFB1) has greatly increased. Several studies found that AFB1 binding to the bacterial cell wall is strain-specific. Moreover, the interaction between AFB1 and

Nestrukturirani modeli mliječno-kiselog vrenja [PDF]

, 2011
To describe a microbial process, two kinds of models can be developed, structured and unstructured models. Contrary to structured models, which take into account some basic aspects of cell structure, their function and composition, no physiological ...

Replacement of Isoleucine and Leucine by their Keto Acids leads to increased formation of α‐Hydroxy Acids in Chinese Hamster Ovary cells

Biotechnology Journal, Volume 20, Issue 6, June 2025.
Graphical Abstract and Lay Summary Keto isoleucine and keto leucine are amino acid precursors, which can be used by CHO cells to produce biotherapeutics. The authors demonstrate that the supplementation of the keto acid derivatives in cell culture feeds alters the levels of related by‐products formed during the process.

Thermal and chemical resistance of Lactobacillus casei and Lactobacillus paracasei bacteriophages [PDF]

Letters in Applied Microbiology, 2004
The survival of two collection Lactobacillus casei and L. paracasei bacteriophages when subjected to thermal and chemical treatments was investigated.Thermal resistance was evaluated by heating phage suspensions at 63, 72 and 90 degrees C in three different media [Tris-magnesium gelatin (TMG) buffer: 10 mmol l(-1) Tris-Cl, 10 mmol l(-1) MgSO(4) and 0.1%
