Classes de genes de resistência expressos por Urochloa decumbens cv. Basilisk e outras seis espécies de Poaceae.

O Urochloa decumbens cv. Basilisk é uma forrageira utilizada devido a sua tolerância a solos com alto teor de alumínio e baixa fertilidade, além de rápido estabelecimento. As forrageiras são constantemente atacadas por outros organismos e possuem, assim, mecanismos pré-formados e induzíveis de autodefesa, que estão relacionados a genes de resistência (Genes R). Esses genes têm papel fundamental no reconhecimento de proteínas específicas expressadas por genes de avirulência (Avr) e podem ser distribuídas em classes que apresentam diferentes mecanismos moleculares, sendo as principais, CNLs, TNLs, RLPs e RLKs. Assim, o objetivo do trabalho foi descobrir os genes de resistência expressos por U. decumbens que sejam comuns aos genes de resistência de outras gramíneas. Foi realizado um estudo do transcritoma de U. decumbens através do sequenciamento Illumina. As sequências foram tratadas e anotadas, e então, organizadas em um banco de dados. Em seguida, retribuíram-se sequências de transcrito primário das gramíneas Setaria italica, Sorghum bicolor, Brachypodion distachyon, Zea mays, Panicum virgatum e Oryza sativa do banco de dados Phytozome, organizando-as em um banco de dados local através de SQL

The Electrochemical Performance and Applications of Several Popular Lithium-ion Batteries for Electric Vehicles - A Review

The Lithium-ion battery is one of the most common batteries used in Electric Vehicles (EVs) due to the specific features of high energy density, power density, long life span and environment friendly. With the development of lithium-ion battery technology, different materials have been adopted in the design of the cathodes and anodes in order to gain a better performance. $LiMn_{2}O_{4}$ , $LiNiMnCoO_{2}$ , $LiNiCoAlO_{2}$ , $LiFePO_{4}$ and $Li_{4}Ti_{5}O_{12}$ are five common lithium-ion batteries adopted in commercial EVs nowadays. The characteristics of these five lithium-ion batteries are reviewed and compared in the aspects of electrochemical performance and their practical applications

Effect of the organic loading rate on the production of polyhydroxyalkanoates in a multi-stage process aimed at the valorization of olive oil mill wastewater

Mixed microbial culture polyhydroxyalkanoates (PHA) production has been investigated by using olive oil mill wastewater (OMW) as no-cost feedstock in a multi-stage process, also involving phenols removal and recovery. The selection of PHA-storing microorganisms occurred in a sequencing batch reactor (SBR), fed with dephenolized and fermented OMW and operated at different organic loading rates (OLR), ranging from 2.40 to 8.40. gCOD/L. d. The optimal operating condition was observed at an OLR of 4.70. gCOD/L. d, which showed the highest values of storage rate and yield (339. ±. 48. mgCOD/gCOD. h and 0.56. ±. 0.05 COD/COD, respectively). The OLR applied to the SBR largely affected the performance of the PHA-accumulating reactor, which was fed through multiple pulsed additions of pretreated OMW. From an overall mass balance, involving all the stages of the process, an abatement of about 85% of the OMW initial COD (chemical oxygen demand) was estimated whereas the conversion of the influent COD into PHA was about 10% (or 22% by taking into account only the COD contained in the pretreated OMW, which is directly fed to the PHA production stages). Overall, polymer volumetric productivity (calculated from the combination of both the SBR and the accumulation reactor) accounted for 1.50. gPHA/L
