1. Bovine colostrum: benefits of its use in human food
Abstract Colostrum is the first secretion of the mammary gland produced after birth, differentiating itself from mature milk because it has a higher concentration of proteins, immunoglobulins, vitamins, minerals, bactericides (lactoferrin, lysozyme and lactoperoxidase) and growth factors. The use of bovine colostrum for human consumption has been registered

2. Oxidative stress and fish immune system: phagocytosis and leukocyte respiratory burst activity
Abstract Molecular oxygen is a necessary compound for all aerobic organisms, although oxygen is a potent oxidant, which can cause oxidative stress (OS). OS occurs when there is an imbalance between the production of oxidant and antioxidants components, are result of normal cell metabolism, and many of these compounds play a fundamental role in several metabo

3. Resistance of Xanthomonas euvesicatoria strains from Brazilian pepper to copper and zinc sulfates
ABSTRACT Bacterial spot, caused by Xanthomonas spp., is one of the major bacterial diseases in pepper (Capsicum annuum L.). The infection results in reduced crop yield, particularly during periods of high rainfall and temperature, due to the low efficiency of chemical control with copper bactericides. This study evaluated the copper and zinc sulfate sensitiv

4. Tipificação de isolados deCurtobacterium flaccumfaciens pv. flaccumfaciens por bacteriocinas.
Este trabalho objetivou avaliar a produção e a sensibilidade à bacteriocinas, de 17 isolados de Curtobacterium flaccum-faciens pv. flaccumfaciens. Doze isolados foram procedentes do Estado de São Paulo e cinco de coleções internacionais. Apenas nove isolados de C. flaccumfaciens pv. flaccumfaciens foram bacteriocinogênicos, e os 17 isolados avaliados

5. Evaluation of the bactericide and bacterostatic activity of violacein / Avaliação da atividade bactericida e bacteriostatica da violaceina
Violacein is a deeply violet indol compound produced by Chromobacterium violaceum, an ubique tropical and subtropical bacterium. This molecule presents many antimicrobial properties, like antimycotic, antiviral and activity against some protists. Important reports pointed to a considerable bactericide activity, which brings an extremely necessary quest. This

6. Estudo Teórico de Mecanismos para a Etapa de Eliminação da Síntese do 5-Enolpiruvilchiquimato-3-Fosfato (EPSP) catalisada pela EPSP Sintase de Oryza sativa.
In the sixth step of the shikimate pathway, catalyzed by 5-enolpyruvylshikimate-3- phosphate synthase (EPSPS), phosphoenolpyruvyl (PEP) reacts with shikimate-3-phosphate (S3P) to produce 5-enolpyruvylshikimate-3-phosphate (EPSP) and inorganic phosphate. Because the shikimate pathway is absent in animals, but is essential for plants and microrganisms, EPSPS i

7. Algoritmo genético e espectroscopia no infravermelho - algumas aplicações na indústria cosmética / Genetic algorithm and infrared spectroscopy - some applications in the cosmetic industry
A genetic algorithm was implemented in VBA for Excel and applied in combination with FTIR-ATR to develop analytical methods for some raw materials and finished products of the home care and personal care industries, like the quantification of surfactants and bactericides. Some modifications were introduced in the traditional genetic algorithm and evaluated f

8. Oxytetracycline in tomatoes and agricultural antimicrobials and evaluation of residues in tomatoes grown in greenhouse and open field. / Oxitetraciclina em tomates e bactericidas agricolas e avaliaçao dos seus residuos em tomates produzidos em estufa e cultura de campo.
Antimicrobials as fungicides and/or bactericides have been used for the improvement of the quality of vegetal products destined to the human feed and for its higher productivity in some phases of its cultivation, such as: preparation of the ground, growth, harvest, industrialization and commercialization. However, several of these compounds can remain as res

9. Estudo fisico-quimico do transporte de especies quimicas atraves de membranas liquidas hidrofobicas em tempo real
Transport processes of variated chemical species - potassium ions, amino acids and vitamins - through hidrophobic liquid membranes was studied using BLM (bulk liquid membrane) method. UV - Vis spectroscopy was used in all cases to quantify the tranported species. It was not possible to use univariate calibration in cases of simultaneous transport because the

10. Rapid Infrared Determination of the Potency of Chlorinated Bactericides
A rapid infrared reflectance method for evaluating the germicidal potency of synthetic materials containing various amounts of two chlorinated bactericides was developed. The dimeric product 2,2′-methylenebis (4,6-dichlorophenol) exhibited a characteristic C=C skeletal inplane stretching infrared absorption band at 1,640 cm−1. The monomeric 2,4-dichlorop

12. Resistance of Bacillus subtilis Spores to Inactivation by Gamma Irradiation and Heating in the Presence of a Bactericide: II. Factors Affecting Rates of Inactivation by Phenolic Bactericides
Aqueous suspensions of Bacillus subtilis NCTC 8236 spores, surviving 150,000 or 300,000 rad of gamma irradiation under air from a cesium-137 source, exhibited an enhanced rate of inactivation, compared to nonirradiated spores, when heated with different phenolic bactericides. The apparent magnitude of the enhanced inactivation rate, observed from survival cu
