A filamentous microorganism, morphologically similar to the cyanobacterium Arthrospira, was isolated from Mangueira Lagoon in Brazil, which Arthrospira has not previously been isolated. Random amplified polymorphic DNA (RAPD) comparison with standard platensis strains LEB 52 and Paracas indicated that organism an isolate, we denominated strain 18. The RAPD analysis showed conserved sequences three belonged same genus, were all species, but there sufficient differences between them suggesting...
Mathematical models taking temperature variations into account are useful in predicting microbial growth foods, like meat products, for which Lactobacillus plantarum is a mesophilic and one of the main spoiling bacterium. The current study assessed ability primary their non-isothermal versions to predict L. under constant variable temperature. Experimental data were obtained MRS medium isothermal conditions (4, 8, 12, 16, 20, 30°C) used obtain secondary models. experimental (periodically...
Mathematical models are widely used to predict the shelf life of foods. Lactic acid bacteria (LAB), particularly Lactobacillus plantarum, Weissella viridescens and sakei, main spoilage refrigerated, vacuum-packed meat products, stored in modified atmosphere, their growth determines length these products. The objective this study was model L. W. sakei under different isothermal cultivation conditions establish secondary describe effect temperature on parameters bacteria. LAB evaluated culture...
Empirical sigmoidal models have been widely applied as primary to describe microbial growth in foods. In predictive microbiology, the maximum specific rate (µ max ) and lag phase (λ) are parameters of some considered biological parameters. The objective current study was propose mathematical equations obtain μ λ for any empirical model. a case study, performance compared two based on These were fitted experimental data Lactobacillus plantarum six isothermal conditions. Some advantages...
Nowadays, microorganisms with probiotic or antimicrobial properties are receiving major attention as alternative resources for food preservation. Lactic acid bacteria able to synthetize compounds activity against pathogenic and spoilage flora. Among them, Lactobacillus plantarum ATCC 8014 has exhibited this capacity, further studies reveal that the microorganism is produce bacteriocins. An assessment of growth L. at different conditions becomes crucial predict its development in foods. A...
Abstract Mangueira Lagoon, located in the extreme south of Brazil, has water with physicochemical characteristics such as alkaline pH and carbonate levels propitious for growth cyanobacterium Spirulina platensis. Previously published studies have shown that Lagoon supplemented small quantities carbon nitrogen is suitable S. platensis cultivation can significantly reduce production costs. We studied mixed cultures toxic Microcystis aeruginosa using a 23 factorial design which three factors...
OIL SUPPLEMENTATION AT DIFFERENT TEMPERATURES.Poly (3-hydroxybutyrate) (P(3HB)) is a biopolymer, completely biodegradable, which has similar properties to fuel-based polymers.However make it economically competitive necessary the study of cheap sources substrate.The influence hydrolyzed rice starch supplemented with soybean oil at different temperatures (30, 35 and 40 °C) was studied in production P(3HB) by C. necator.The percentage produced cultures 30, °C 39% 35, 43% without...
Summary L actobacillus plantarum growth in a vacuum‐packaged cooked meat product under different storage temperatures (4, 10 and 16 °C) the relation between microorganism sensory quality were investigated. The G ompertz model was fitted to experimental counts of . showing good fitting curves at temperatures. A root‐square secondary linear satisfactorily estimated rates ( ) lag times ), respectively. attributes (colour, flavour, taste, appearance) also evaluated due their importance global Q...
THROUGH ADDITIVATION WITH ZINC BASED COMPOUNDS.Antimicrobial packaging is a promising type of active packaging, which has an antimicrobial agent incorporated into the polymer matrix, capable to eliminate or inhibit deteriorating and/or pathogenic microorganisms.The zinc compounds are agents commonly used confer this feature.The objective work was evaluate activity biodegradable Ecoflex ® films with 1% and 2% (w/w) oxide nanoparticles (ZnO NPs) glass microparticles doped ionic (Zn MCs),...
Infecções ocasionadas por microrganismos patogênicos são um problema de saúde pública que demandam atenção e estudo já há algum tempo. Novos agentes antimicrobianos despertam interesse estudo, visando o desenvolvimento materiais confiram atividade antimicrobiana. Tendo em vista esta problemática, este trabalho tem como objetivo estudar a antimicrobiana nanopartículas óxido zinco (NPs-ZnO) dióxido titânio (NPs-TiO2) frente às bactérias Staphylococcus aureus (S. aureus) Escherichia coli (E....
Abstract Geraniol has been an attractive compound for food preservation due to its antibacterial and antifungal actions. The main objective of this study was produce characterize polycaprolactone (PCL) capsules the protection encapsulated geraniol essential oil. encapsulation carried out using a miniemulsion polymerization technique with efficiency (95.44 ± 0.60%). were obtained mean size 148 nm polydispersity index 0.12. Transmission electron microscopy results confirmed formation spherical...
O interesse da sociedade por um desenvolvimento sustentável vem crescendo nos últimos anos. A preocupação com o meio ambiente, a busca uma melhor qualidade de vida e os critérios econômicos precisam andar em paralelo. Dentro área tecnologia informação, novas tecnologias surgem dia após dia, fazendo que muitas outras se tornem obsoletas. Para exemplificar exposto, pode-se citar monitores Cathode-ray Tube (CRT) cederam espaço às telas Liquid Crystal Display (LCD), sua vez perderam posto para...

Utilizar metodologias diferenciadas pode trazer benefícios para o aprendizado dos discentes, promovendo transformações no método de ensino, sendo este grande desafio atual. Nesse sentido, apresentam-se as ativas como uma ferramenta promoção do processo ensino-aprendizagem, que insere aluno autônomo na sua busca pelo conhecimento. Assim, objetivo deste estudo foi avaliar a percepção acadêmicos cursos Engenharia Química e Alimentos perante à utilização ensino em duas aulas ministradas. Para...
A geração de resíduos pela agroindústria pode configurar um problema ambiental. O bagaço malte, originado em grande quantidade na produção cerveja, corresponde até a 85% dos gerados nesse processo e tem como principal destino alimentação animal ou aterros sanitários. Devido sua constituição nutricional, ser utilizado elaboração alimentos para consumo humano. Nesse sentido, buscou-se desenvolver avaliar pães elaborados partir do resíduo malte proveniente da cervejas estilo Pilsen Porter. Para...
