    The Upper Cretaceous Bauru Basin developed in the south-central part of the South American Plate resulting from the thermo-mechanical subsidence processes which followed the break-up of Gondwana and the opening of the Southern Atlantic Ocean (Figs. 1 to 3). In this inland basin it was developed an essentially sandy, 300 m thick siliciclastic, alluvial and aeolian dominated sequence (red beds), the so called Cretaceous Suprabasaltic Sequence -¡.e. "Secuencia Suprabasáltica Cretácica" (SSC). This sequence presently occurs in a very extensive area of 370,000 km2 and unconformably overlies the mainly basaltic Neocomian Paraná Volcanic Floods (Sena Geral Formation), from which it is separated by an erosive surface (Figs. 4 and 5). The sequence deposits extend between 18OS and 24OS latitudes and 47OW and 56OW longitudes covering parts of the states of SEO Paulo, Paraná, Mato Grosso do Sul, Minas Gerais and Goiás in Brazil. It also occurs in northeastem Paraguay. A stratigraphic review of the whole SSC, based on studies developed mainly on the southwestern part of the basin is shown in this paper which also deals with the structural, paleoclimatic and paleogeographic settings of the basin. The sedimeniological features, depositional environments and paleogeographic distribution of the defined stratigraphic units is analyzed, as well as their general resulting implications on the paleobiological record (Figs. 5 to 7). The sequence is formed by two synchronous groups, the aeolian dominated Caiuá Group and the alluvial dominated Bauru Group. and was deposited in an asymmemcal closed basin, which underwent climatic conditions ranging from semi-and at its margins to dessertic in the inner basin zones. Alluvial sedimentation in the Bauru basin was simultaneous with the progressive uplift of its margins, constituted by tectonic uplifts which separated the basin from other neighbouring cretaceous basins. Life in the Bauru Basin developed best in areas with largest water supply, such as in the broad braid plains, where ephemeral carbonate water shallow lakes and ponds developed. Reptiles (mainly dinosaurs, crocodiles and turtles) dwelled there. Increasing aridity resulted in the gradual reduction in the paleobiological diversity as recorded in the inner, central basinal aeolian dominated units, with an almost complete lack of fossils in the sand sea deposits of the central paleodessert

    CONTROLE BIOLÓGICO DE Meloidogyne incognita POR ISOLADOS DE ACTINOMICETOS

    Get PDF
    The Cerrado biome has great biodiversity and also includes part of the agricultural production of the country being used for the cultivation of large crops. The nematode of the Meloidogyne incognita galls can cause significant losses in the cotton crop, as well as the fungus Sclerotinia sclerotiorum that causes damage to several crops of economic importance. Among the microorganisms with potential for phytopathogen control, actinomycetes are known for the ability to produce compounds with antimicrobial action. The objective of this work was to isolate and evaluate the antagonistic potential of actinomycetes of native soils of the Cerrado Baiano area against M. incognita and S. sclerotiorum. It was obtained 18 isolates of actinomycetes and among the tested isolates, AC. O, presented the highest percentage of immobility with 99.16% and AC. R, showed the highest percentage of mortality with 72.16% of the J2 of M. incognita. Effective control of M. incognita in cotton was not observed in vivo. However, with the rotation system with soybean, the AC isolate. G, showed a significant reduction in the number of galls and eggs in the cotton root system. With respect to the antagonism of actinobacteria against S. sclerotiorum, by the pairing of cultures, the isolate AC. M, inhibited 81.99% of the mycelial growth of this phytopathogen. The results of the present work show the potential of control of phytopathogens tested by actinomycetes, since a great part of cotton production is found in Cerrado areas and these microorganisms were isolated from this biome.O bioma Cerrado possui grande biodiversidade e também comporta parte da produção agrícola do país sendo utilizado para o cultivo de grandes culturas. A cotonicultura brasileira vem sendo cultivada em alto grau de tecnificação, sendo os principais estados produtores são o Mato Grosso e a Bahia. O nematoide das galhas Meloidogyne incognita pode causar perdas significativas na cultura do algodoeiro, assim como o fungo Sclerotinia sclerotiorum que provoca danos a diversas culturas de importância econômica. Dentre os microrganismos com potencial para controle de fitopatógenos, os actinomicetos são conhecidos pela capacidade de produzir compostos com ação antimicrobiana. Objetivou-se com o presente trabalho isolar e avaliar o potencial antagônico de actinomicetos de solos de área nativa do Cerrado Baiano contra M. incognita e S. sclerotiorum. Foram obtidos 18 isolados de actinomicetos e dentre os isolados testados, AC. O, apresentou o maior percentual de imobilidade com 99,16% e AC. R, mostrou o maior percentual de mortalidade com 72,16% dos J2 de M. incognita. Quando os isolados foram inoculados diretamente na cultura do algodão dois dias antes da inoculação com os nematoides, não foi observado in vivo um controle eficiente de M. incognita no algodoeiro. Entretanto, utilizando o sistema de rotação de cultura com a soja inoculada com os isolados de actinomicetos e sendo cultivada anteriormente a cultura do algodão, foi verificado que o isolado AC. G, mostrou redução significativa no número de galhas e ovos no sistema radicular do algodoeiro. Com relação ao antagonismo das actinobactérias frente a S. sclerotiorum, pelo pareamento de culturas, o isolado AC. M, inibiu 81,99% do crescimento micelial desse fitopatógeno. Os resultados do presente trabalho mostram o potencial de controle dos fitopatógenos testados pelos actinomicetos, visto que grande parte da produção de algodão é encontrada em áreas de Cerrado e esses microrganismos foram isolados desse bioma

    Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
