Photocurable bioadhesive based on lactic acid

Antifungal activity of nano-composite films based on Poly Lactic Acid

Objective(s): Nanocomposite active packaging systems were used to prepare antimicrobial and antifungal properties. This study was to investigate the physical and antimicrobial activity of prepared films against three types of aflatoxin producing fungi Aspergillus Flavus. Material and methods: For investigating the effect of antibacterial nano-covers, the direct contact of 0, 1%, 3% and 5%...

Formulation of Modified Microspheres Based on Cyclodextrin-Lactic Acid Polymers

Polymers, based on Poly L-lactic acid (L-PLA) and coupled with β-Cyclodextrin (β-CD), have been used for the preparation of microspheres for drug encapsulation. The strategy was based on the modification of the terminal carboxylic group of L-PLA (73.000) by coupling it with a β-CD in the presence of the peptide coupling agents: DCC/HOBT. The degree of functionalisation was found to be 80%. Char...

Destructive effects of citric acid, lactic acid and acetic acid on primary enamel microhardness

  Objective: This study aimed to assess the destructive effects of citric acid, lactic acid and acetic acid produced from the fermentation of foods on primary teeth enamel.   Methods: This in vitro, experimental study was conducted on 24 sound primary teeth. The teeth were polished with a fine abrasive paper under running water. Tooth pieces measuring 3 × 4 × 3mm were cut out of the teeth and s...

9th International Symposium on Lactic Acid Bacteria.

Lactic Acid Bacteria

Lactic acid bacteria comprise an ecologically diverse group of microorganisms united by formation of lactic acid as the primary metabolite of sugar metabolism (Davis et al., 1985b; 1988; Lonvaud-Funel, 1999; Carr et al., 2002; Liu, 2002). These bacteria utilize sugars by either homoor heterofermentative pathways (Section 2.4.1) as well as l-malic acid, a major acid present in grape must (Sectio...
