Dry bacterial cellulose nanofiber (BC) sheet coated with poly(lactic acid) (PLA) was developed and characterized towards acute wound healing applications. This new approach of PLA coating on BC revealed enhanced physical and antibacterial properties. Commercial BC sheets originated from the manufacturing...
In this study, 3D-printed biodegradable poly(lactic acid) (PLA) and hybrid PLA scaffolds doped with magnetite nanoparticles (PLA/Fe3O4) and having gyroid structure were investigated at various infill densities (100%, 70%, 50%, or 30%). Effects of infill density on the composition, structure...
4.2Hydroxycinnamic acid derivatives As reported byAmoah et al. (2015),rosmarinic acidand isorinic acid (caffeoyl-4′-hydroxy-phenyllactic acid) have been isolated from the fresh leaves ofH. brasilienseby hot infusion; isorinic acid is considered an intermediate in thebiosynthesisof rosmarinic acid...
Lactic acid is a versatile chemical platform with many different industrial applications. Yeasts have been demonstrated as attractive alternative to natural lactic acid producers since they can grow at low pH, allowing the direct purification of the product in the desired acidic form. However, when ...
The majority of baeteriocins produced by lactic acid bacteria have been characterized by the ini- tial definition of a proteinaceous inhibitor, esti- mation of molecular mass (via retention in dialy- sis membranes, ultrafiltration, molecular sizing, or mass spectrometry), and determination of sus...
3 Add the remaining Water, Yeast Nutrient, Pectic Enzyme and Tartaric Acid. Add 5 crushed Campden Tablets. 4 Cover with loose plastic sheet or lid and allow to cool and dissipate the sulfite, waiting for 12 hours or overnight. 5 Stir in the Yeast. Once fermentation begins, stir or push...

Poly(lactic acid) electrospun membranes Cellulose nanofibrils Silver nanoparticles Cell proliferation Antimicrobial Ocular bandages 1. Introduction Ocular infections are common worldwide, damaging the ocular micro-environment, especially the structure of the cornea, resulting in visual disability or even blindne...
Nagoya Protocol Probiotics Lactic Acid Bacteria Access and Benefit Sharing Legislation Convention on Biological Diversity 1. Introduction Genetic resources (GRs) are genetic material of actual or potential value which contain functional units of heredity and can be used in crop protection, food and drug...
Fermented mango leathers were produced from two mango varieties (apple and ngowe) using Lactic acid bacteria (LAB) strains; Lactobacillus plantarum (DCRUST PKLP4) and Lactobacillus casei (LC-1). Fermentation for 24 hours was adequate and it reduced pH, total soluble solids, and fibre content ...
