Resumo: The objective of this work was to identify microbial communities associated with the surfaces of alkali feldspars and to determine whether these microbes might be involved in the weathering of these rocks for agronomic benefit. Samples were taken from weathering profiles and soils developed on a syenite, considered as a raw material for agromineral production, located in the municipality of Triunfo, in the state of Pernambuco, Brazil. Molecular microbiological techniques (qPCR and 16S rRNA gene sequencing) were used, and data were interpreted by the analysis of variance, hierarchical cluster analysis, and principal coordinates analysis. In addition, scanning electron microscopy was used to image mineral surfaces. Similar bacterial communities were observed in all samples, showing that the bacteria found in soil are present at the earliest stages of rock weathering and are available to play a role in nutrient release. In particular, Actinobacteria and, within this phylum, Actinomycetales were proportionally more abundant than other taxa in rock-dominated soil samples, i.e., in thin soils on or between fractured or broken syenite. The analysis of rock dust used as a remineralizer, crushed with no further treatment, shows that Actinobacteria play a role in the early stages of weathering of feldspar-bearing rocks.

As amostras foram coletadas de perfis intemperizados e solos desenvolvidos sobre um sienito, considerado como matéria prima para produção de agrominerais, localizado no município de Triunfo, no estado de Pernambuco, Brasil. Foram usadas técnicas de microbiologia molecular (qPCR e sequenciamento de genes 16S rRNA), e os dados foram analisados por análise de variância, análise de grupos hierárquicos e análises de coordenadas principais. Além disso, utilizou-se a microscopia eletrônica de varredura para gerar imagens das superfícies minerais. Foram observadas comunidades similares em todas as amostras, o que mostra que as bactérias encontradas nos solos estão presentes nos estágios iniciais do intemperismos da rocha e estão disponíveis para desempenhar um papel na liberação de nutrientes. Em particular, Actinobacteria e, dentro desse filo, Actinomycetales, foram proporcionalmente mais abundantes do que os outros táxons nas amostras de solo dominadas por rochas, isto é, em solos finos sobre ou entre sienito fraturado ou quebrado. A análise do pó de rocha usado como remineralizador, moído sem outros tratamentos, mostra que Actinobacteria desempenham um papel nos estágios iniciais do intemperismo de rochas compostas por feldspatos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraTerrativa Minerais S.A.Bruno Timóteo RodriguesJoão LedaErika PachecoTerrativa Minerais S.A.Bruno Timóteo RodriguesJoão LedaErika PachecoBaptista, Joana de CarvalhoGray, Neil DuncanTarumoto, Miriam BüchlerSingleton, IanMcCann, Clare MariaManning, David Andrew Charles2022-05-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/27036Pesquisa Agropecuaria Brasileira; V.57, Jan./Dec., 2022: Publicação contínua em volume anual; e01414Pesquisa Agropecuária Brasileira; V.57, Jan./Dec., 2022: Publicação contínua em volume anual; e014141678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/27036/14981Direitos autorais 2022 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2023-01-23T13:40:23Zoai:ojs.seer.sct.embrapa.br:article/27036Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2023-01-23T13:40:23Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
