In order to get a better knowledge of mechanical properties from microscopic macroscopic scale biopolymers, viscoelastic bulk aqueous solutions sodium alginate were studied at different...

The aim of this study was the preparation and characterization of a bioluminescence bacteria sheet in view of the fabrication of an oxygen marker inside a biofilm. Photobacterium kishitanii sheets were prepared using sodium alginate, and a biofilm of Pseudomonas aeruginosa was dropped over it. The relationship between the dissolved oxygen (DO) concentration in the biofilm and luminescence fro...

The effect of Ultra-Violet (UV) irradiation and acridine orange dye on L-glutamic acid producing Bacillus subtilis B. megaterium was investigated. selected mutant strains wild types were immobilized used for production. exposed to UV treated with respectively. survived found reduce as the exposure time concentration mutagens increased in this study. Four mutants two Mutant strain (MAIR4) yielde...

Background: Although advantages of immobilization of cells through entrapment in calcium alginate gel beads have already been demonstrated, nevertheless, instability of the beads and the mass transfer limitations remain as the major challenges.Objective: The objective of the present study was to increase the stability, porosity (reduce mass transfer limit...

The objective of the present work was to evaluate novel active films made with biopolymeric matrices as carriers a living Bdellovibrio bacteriovorus HD100 strain, predatory bacterium antimicrobial potentials against pathogens. Biopolymer were prepared by casting method using following mixtures: collagen/sodium alginate/sorbitol (CA-S), alginate/glycerol (CA-G), and tapioca starch/sodium (StA-G)...

Alginate impression material is a that often used in dentistry to produce study models. The main active ingredient the alginate sodium alginate, which can be obtained naturally from algae. turbulent water (Waters on village Agel, Situbondo) and structure of aliginate gluronic acid form gel influence viscosity porosity material. Purpose was analyze red algae Kappaphycus alvarezii. This laborator...

Potentiometric sensing and electrochemical recycling of cadmium ion have been demonstrated over chemical interactive electrically conducting bio nanocomposite film comprised zinc oxide, sodium alginate, polypyrrole (ZnO/SA-g-PPy) using...

The present work investigated the preparation of biodegradable beads with alginate polymer by ionotropic gelation method to improve the control release properties of the antibiotic rifampicin. Ionotropic gelation method was applied to prepare beads using calcium chloride (CaCl2) as cationic component and alginate as an anionic component. In this method, adding 0.5% w/v polyvinyl alcohol (PVA) t...
