13. Processes that influence dissolved organic matter in the soil: a review
ABSTRACT: In tropical regions, climate conditions favor fast decomposition of soil organic matter (SOM), releasing into the soil organic composts in solid, liquid, and gaseous forms with variable compositions. Dissolved organic matter (DOM), a complex mixture of thousands of organic compounds, is only a small fraction of the decomposition products; however,

14. Morphological identification of Ilyonectria liriodendri and its interaction with plant growth-promoting bacteria in grapevine rootstocks
Resumo Com a finalidade de analisar a patogenicidade e o antagonismo entre porta-enxertos de videiras e microrganismos de solo, procedeu-se à seleção de bactérias promotoras de crescimento de plantas com efeito antibiótico ao fitopatógeno Ilyonectria liriodendri, isolado monospórico 2T-VSC-101, em testes de antibiose in vitro. O acesso bacteriano que

15. COINOCULATION WITH Bradyrhizobium AND Trichoderma ALLEVIATES THE EFFECTS OF SALT STRESS IN COWPEA
RESUMO Os efeitos deletérios do estresse salino podem ser mitigados pelo uso de microrganismos benéficos. O objetivo foi avaliar se a inoculação com Bradyrhizobium e Trichoderma asperelloides alivia o estresse salino em feijão-caupi. O experimento foi conduzido em casa de vegetação utilizando vasos preenchidos com solo estéril. As sementes foram seme

17. Micro-organismos endofíticos e níveis de nitrogênio no crescimento de plantas de arroz
RESUMO Os micro-organismos endofíticos podem estimular o crescimento a depender da interação com a planta hospedeira e da disponibilidade de nutrientes no solo. O objetivo deste trabalho foi avaliar o crescimento de plantas de arroz BRS Tropical cultivadas com fungos endofíticos e níveis de adubo nitrogenado em estufa agrícola. O delineamento experimen

18. Physical, Chemical, and Microbiological Properties of Soil under Different Plant Covers in the Seridó Desertification Region in the Brazilian Semiarid
ABSTRACT The Seridó Desertification Region is a result of inadequate management of the native Caatinga vegetation, which generated degraded areas with little or no capacity for plant production. The area has experienced a succession of different land uses, but little is known about the impact of these changes. The present study tested the hypothesis that th

19. Competitive Capacity and Rhizosphere Mineralization of Organic Matter During Weed-Soil Microbiota Interactions
RESUMO: A competição entre plantas daninhas e culturas é um dos principais fatores responsáveis por perdas de produtividade nos campos agrícolas. Esta revisão teve como objetivo apresentar e discutir como a interação entre plantas daninhas e microrganismos pode afetar a capacidade competitiva de plantas daninhas, bem como as propriedades físico-quí

20. Effects of Simulated Nitrogen Deposition and Precipitation Manipulation on Soil Microorganisms in the Desert Steppe of Northern China
ABSTRACT: Soil microorganisms are influenced by climate change. However, the effect of climate change on soil cultivable bacteria are unclear. In this study, the composition and diversity of the soil cultivable bacterial community were explored by a dilution–plate method, PCR, and 16S rRNA sequencing in a desert steppe of northern China after repeated NH4N

21. Cupriavidus necator strains: zinc and cadmium tolerance and bioaccumulation
ABSTRACT: Among soil microorganisms, the genus Cupriavidus has garnered particular scientific, economic and ecological interest because of its ability to fix nitrogen and tolerate high concentrations of metals. The aim of this study was to analyze four strains of Cupriavidus necator for their ability to tolerate and bioaccumulate cadmium and zinc. The tolera

22. Occurrence of Yeast Species in Soils under Native and Modified Vegetation in an Iron Mining Area
ABSTRACT Soils of the Quadrilátero Ferrífero are rich in mineral resources, especially gold and iron. Soil management and mining activities greatly impact soil biology. However, studies addressed to the diversity of microorganisms and their ecological role in the recovery of these areas are scarce. This study aimed to assess the yeast occurrence in soils w

23. Biofilm Formation and Corrosion on Carbon Steel API 5LX60 in Clayey Soil
Corrosion of buried pipelines is a matter of concern to the oil and gas industry since the time when carbon steel began to be widely used in these pipelines for the transportation of fluids. The microbial communities associated with biofilms promote modification in the surrounding environment and may accentuate the degradation of oil and gas pipelines causin

24. POLÍMERO BIODEGRADÁVEL ANTIMICROBIANO ATRAVÉS DA ADITIVAÇÃO COM COMPOSTOS À BASE DE ZINCO
Antimicrobial packaging is a promising type of active packaging, which has an antimicrobial agent incorporated into the polymer matrix, capable to eliminate or inhibit deteriorating and/or pathogenic microorganisms. The zinc compounds are antimicrobial agents commonly used to confer this feature. The objective of this work was to evaluate the antimicrobial a
