Medium composition and optimization of Lactic acid production by Lactobacillus plantarum Lmism-6 grown in molasses
(Journal of Biotechnology, 2010-11-01) [Resumo]
Transport of amino acids from milk whey by Caco-2 cell monolayer after hydrolytic action of gastrointestinal enzymes
(Food Research International, 2014-09-01) [Artigo]
The bioavailability of amino adds from milk whey protein hydrolysates was evaluated using diffusion of the substances through semi-permeable membranes (dialyzability) and transport by Caco-2 cell cultures. The hydrolysates ...
Lactic acid production by new Lactobacillus plantarum LMISM6 grown in molasses: optimization of medium composition
(Brazilian Journal of Chemical Engineering, 2011-03-01) [Artigo]
A Plackett-Burman experimental design was used to evaluate seven medium components added to molasses (corn steep liquor, sodium acetate, magnesium sulfate, manganese sulfate, ammonium citrate, potassium phosphate and Tween ...
Rhamnolipids Production by a Pseudomonas eruginosa LBI Mutant: Solutions and Homologs Characterization
(Tenside Surfactants Detergents, 2014-09-01) [Artigo]
This paper evaluates the effect of additives (NaCl and ethanol) on the solution properties of rhamnolipids. The properties are the surface activity, aggregate formations and emulsifying activity as well as the synergistic ...
Bacillus lehensis-an alkali-tolerant bacterium isolated from cassava starch wastewater: optimization of parameters for cyclodextrin glycosyltransferase production
(Annals of Microbiology, 2012-03-01) [Artigo]
A Gram-positive, endospore-forming, alkali-tolerant bacterial strain, designated CGII, was isolated from the wastewater of a cassava flour mill in the state of São Paulo, Brazil and submitted to phylogenetic studies and ...
Rhamnolipid emulsifying activity and emulsion stability: pH rules
(Colloids and Surfaces B: Biointerfaces, 2011-07-01) [Artigo]
Rhamnolipids have excellent emulsifying power with a variety of hydrocarbons, aromatic compounds and vegetable oils. This paper evaluates the effect of pH ranging from 3 to 9 on the emulsifying activity and stability of ...
