Azospirillum sp. strain Sp245 T , originally identified as belonging to brasilense is recognized a plant-growth-promoting rhizobacterium due its ability fix atmospheric nitrogen and produce plant-beneficial compounds. other related strains were isolated from the root surfaces of different plants in Brazil. Cells are Gram-negative, curved or slightly rods, motile with polar lateral flagella. Their growth temperature varies between 20 38 °C their carbon source utilization similar species. A...
Strain Az39T of Azospirillum is a diazotrophic plant growth-promoting bacterium isolated in 1982 from the roots wheat plants growing Marcos Juárez, Córdoba, Argentina. It produces indole-3-acetic acid presence l-tryptophan as precursor, grows at 20-38 °C (optimal 38 °C), and cells are curved or spiral-shaped, with diameters ranging 0.5-0.9 to 1.8-2.2 µm. They contain C16 : 0, C18 0 1 ω7c/ω6c main fatty acids. Phylogenetic analysis its 16S rRNA gene sequence confirmed that this strain belongs...
<title>Abstract</title> In this study, we characterized 86 plant growth-promoting bacterial strains belonging to the genus <italic>Nitrospirillum</italic>, isolated from diverse host plants and geographic regions. To investigate their evolutionary relationships, employed phylogenetic analyses based on 16S rRNA <italic>recA</italic> genes, as well phylogenomic approaches including average nucleotide identity (ANI) digital DNA–DNA hybridization (dDDH). The classification of type was further...
Este trabalho tem por objetivo, a luz da estimacao de uma funcao custo, verificar se empresas brasileiras aviacao regional atuantes em regioes que diferem com relacao proximidade dos centros distribuicao querosene (QAv), apresentam diferentes sensibilidades nos seus custos variacoes no preco desse insumo. Procura-se, assim, testar hipotese logistica na aquisicao fator producao e um elemento fundamental determinacao estrutura das companhias e, conseguinte, competitividade mesmas. Os...
ABSTRACTABSTRACTThis work aimed to evaluate the use of phosphorus (P) fertilizer, rhizobia inoculation, and seed enrichment with molybdenum (Mo) as tools for enhancing cowpea yield in Brazilian eastern Amazon. A set field greenhouse experiments were carried out cerrado upland forest environments. Four levels P fertilization, eight strains, application mineral nitrogen (N) evaluated cultivar BRS Tumucumaque (BR = Brasil e S Sementes), two Mo assessed cultivars Guariba. Grain increased...
Abstract: The objective of this work was to evaluate the response BRS Tumucumaque cowpea (Vigna unguiculata) cultivar liming and phosphorus potassium fertilization in absence inoculation or nitrogen fertilization, as well with selected Bradyrhizobium strains, an upland forest area state Amapá, eastern Amazon, Brazil. Seven experiments were conducted field conditions, order six limestone, four phosphorus, rates, besides strains. Leaf concentrations, pod grain dry mass per plant, yield, soil...
Resumo Este artigo tem por objetivos a discussao de fenomenos guerras preco no setor aereo e proposicao modelagem parâmetro conduta da Nova Organizacao Industrial Empirica (NOIE) para identificacao do comportamento das firmas, fim se distinguir uma anticompetitiva predacao firmas um competicao normal, porem acirrada. O estudo caso realizado compreendeu analise companhias aereas brasileiras mercado relevante compreendido pela Ponte Aerea Rio Janeiro (aeroporto Santos Dumont) – Sao Paulo...

This paper aims at making inference regarding the competitive conduct of beer manufacturers in Brazil and investigating alleged predatory behavior market from data disaggregated brand level. By use theoretical framework on predation New Empirical Industrial Organization methodology, we propose a structural model conduct, based game Bertrand competition with product differentia tion, order to better represent rivalry among players this important market. Final results revealed that it is not...
