Draft genome sequence of the N2-fixing cyanobacterium Nostoc piscinale CENA21, isolated from the Brazilian Amazon floodplain

We announce here the draft genome sequence of Nostoc piscinale CENA21, a diazotrophic heterocyst-forming cyanobacterium isolated from the Solimões River, Amazon Basin, Brazil. It consists of one circular chromosome scaffold with 11 contigs and total size of 7,094,556 bp. Secondary metabolite annotations indicate a good source for the discovery of novel natural products. © 2016 Leão et al.This work has been supported by grants from the Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) and from the Funda ção de Amparo à Pesquisa do Estado do Pará (BIONORTE-CNPq/FAPESPA) to M.P.C.S.

Whey protein supplement as a source of microencapsulated PUFA-rich vegetable oils

Whey protein supplements (WPS) intake has been increasing worldwide as they are mainly used to improve overall athletic performance. Adding other bioactives such as polyunsaturated fatty acids (PUFA) may be an alternative to help fulfill nutritional needs. Microencapsulation is able to protect PUFA-rich oils from oxidation, but important aspects of particle production and their influence on food properties must be evaluated. This study aimed to develop WPS with microencapsulated green coffee and walnut oils using stearic acid as a wall material. Oxidative stability (differential scanning calorimetry) of the oils increased (from 82 ± 4 to 110 ± 10 kJ mol−1 for green coffee oil and from 90 ± 5 to 149 ± 1 kJ mol−1 for walnut oil) after encapsulation and WPS rheological properties were not affected by the microcapsules (p 0.05). Sensory analysis of the supplement containing microencapsulated green coffee oil showed a lower sensory preference than the blank sample, but no difference was found with the blank sample in the case of walnut oil (p 0.05). The encapsulation strategy used to produce an enriched WPS was efficient in protecting the oils from oxidative degradation.This study was financed in part by the Coordenaç~ao de Aperfeiçoamento de Pessoal de Nível Superior - Brasil (CAPES) - Finance Code 001.

Formulation of mayonnaises containing PUFAs by the addition of microencapsulated chia seeds, pumpkin seeds and baru oils

There is an increasing demand for healthier foodstuff containing specific compounds such as Polyunsaturated Fatty Acids (PUFAs). In the case of PUFAs, protection against oxidative degradation is challengeable and microencapsulation emerges as an alternative. Mayonnaises containing microencapsulated oils could be a source of PUFAs. The objective was to formulate mayonnaises containing microencapsulated chia seeds oil, pumpkin seeds oil or baru oil. Micrometric particles with high encapsulation efficiency were produced and thermal analyses indicated an increased thermal stability of all oils after encapsulation. Rheology studies highlighted an increase in the mayonnaise viscosity when microparticles containing chia and pumpkin seeds oil were added. Mechanical texture was not affected by the presence of microparticles in the mayonnaise in all formulations tested. Nevertheless, samples containing microcapsules up to 5%wt were not distinguished from the base-mayonnaise in the sensorial test. Overall, enriched mayonnaises were successfully produced and encapsulation was efficient in protecting oils from oxidation.Authors thank CAPES , CNPq and Fundação Araucária for the support.

Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in √s = 7 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb−1 of proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results
