d(-)-Lactic Acid Production by Leuconostoc mesenteroides B512 Using Different Carbon and Nitrogen Sources
(Applied Biochemistry and Biotechnology, 2011-08-01) [Artigo]
Sugar concentration from sugarcane juice and yeast autolysate increased lactic acid production more than the other agro-industrial substrates tested. The concentrations of these two components were further optimized using ...
Rhamnolipids and PHAs: Recent reports on Pseudomonas-derived molecules of increasing industrial interest
(Process Biochemistry, 2011-03-01) [Artigo]
Rhamnolipids (RL) and polyhydroxyalkanoates (PHA) from Pseudomonas species show a wide range of potential industrial applications. Rhamnolipids are surface-active molecules that are usually produced by Pseudomonas aeruginosa ...
Expressed sequence tags from Atta laevigata and identification of candidate genes for the control of pest leaf-cutting ants.
(BMC Research Notes, 2011-06-17) [Artigo]
Leafcutters are the highest evolved within Neotropical ants in the tribe Attini and model systems for studying caste formation, labor division and symbiosis with microorganisms. Some species of leafcutters are agricultural ...
Avaliação do potencial antagônico de leveduras, visando biocontrole de deterioração por penicillium expansum
(Semina: Ciências Agrárias, 2011-12-01) [Artigo]
Considerable losses during apple fruit storage occur due to microbiological diseases, mainly caused by Penicillium expansum, which in addition to fruit pulp deterioration produces patulin, a mycotoxin with carcinogenic and ...
Influência da geometria e umidade de colunas de solo na biodegradação de filmes de PCL
(Polímeros, 2011-01-01) [Artigo]
Filmes de poli(ε-caprolactona) (PCL) foram preparados por compressão a quente e investigados com respeito a sua biodegradação em diferentes colunas de solo, após 60 dias. A morfologia e estrutura dos filmes, após os ...
Analytical Methods in Photoelectrochemical Treatment of Phenol
(Journal of the Brazilian Chemical Society, 2011-09-01) [Artigo]
The aim of the study was to propose a treatment of simulated wastewater containing phenol by photocatalytic and photolytic processes and analyze the toxicity of these phenolic solutions. Two treatment systems were performed ...
Purification and some properties of an extracellular acid protease from Aspergillus clavatus
(World Journal of Microbiology & Biotechnology, 2011-11-01) [Artigo]
Acid proteases represent an important group of enzymes, widely used in food, beverage and pharmaceutical industries. For most of these applications the enzymatic preparation must be at least partially purified and free of ...
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 ...
Photoeletrolytic system applied to remazol red brilliant degradation
(Water Science and Technology, 2011-01-01) [Artigo]
Toxicity tests using Sacharomycces cerevisiae were made with simulated textile effluents containing reactive dye (remazol red brilliant) treated by photoeletrolytic process, varying treatment time and applied current. The ...
