1. Microbiological Indicators of Soil Quality Under Native Forests are Influenced by Topographic Factors
Abstract: Several microbiological indicators of soil quality present high sensitivity, but little is known about the influence of topographic factors on them. This work aimed to evaluate variability of biological indicators of soil quality across a hillslope under native forest and the influence of topographic factors on them. Four positions on a hillslope w

2. Is Increasing Doses of Imazapyr + Imazapic Detrimental to the Main Crop Rotation Alternatives to Flooded Rice?
RESUMO: A mistura formulada de imazapyr + imazapic é o principal herbicida usado para o controle de plantas daninhas em arroz no sistema Clearfield®. O uso contínuo de altas doses pode aumentar sua atividade residual no solo. O objetivo deste trabalho foi determinar a sensibilidade de culturas de cobertura e soja em rotação com arroz irrigado a diferent

3. Heavy Metals and 2,4-Dinitrophenol Impact on Some Physiological and Biochemical Parameters in Capsicum Species
Abstract The accumulation of heavy metals and of pesticides in the soil have a negative impact on Capsicum chinense var. Aji Mochero and Capsicum baccatum var. pendulum Bishop's Crown species, the present work highlighting the exerted influence on the superoxid-dismutase activity, catalase and peroxidase - as enzymes implied in the removal of H2O2, of O2- ra

4. Endophytic Actinomycetes as Potential Producers of Hemicellulases and Related Enzymes for Plant Biomass Degradation
Abstract Tailor made enzymatic preparation must be design to hydrolyze efficiently plant biomass, once that each plant biomass possesses a distinct cell wall composition. Most of actinomycetes used for plant cell wall degradation are focused on the cellulases and xylanases production. However, a wide range of enzymes must be produced for an efficient degrada

5. [PROVISIONAL] Boundaries in metagenomic screenings using lacZα-based vectors
Article Metagenomics approaches have been of high relevance for providing enzymes used in diverse industrial applications. In the current study, we have focused on the prospection of protease and glycosyl hydrolase activities from a soil sample by using the lacZα -based plasmid pSEVA232. For this, we used a functional screen based on skimmed milk agar and a

6. Corrective phosphate application as a practice for reducing oxidative stress and increasing productivity in sugarcane
RESUMO A fosfatagem aumenta os teores de fósforo (P) na camada superficial do solo, estimula o crescimento das raízes das plantas e aumenta o volume de solo explorado para absorção de água e nutrientes, o que pode reduzir o estresse oxidativo abiótico na cana-de-açúcar. O objetivo deste trabalho foi avaliar a produtividade e a resposta do sistema enz

7. Tolerance of crambe (Crambe abyssinica Hochst) to salinity and water stress during seed germination and initial seedling growth
RESUMO Crambe é uma oleaginosa adequada para vários fins industriais, como a produção de biodiesel, plásticos, borrachas e cosméticos. Há relatos da rusticidade desta espécie e seu potencial para o plantio em ambientes áridos e semi-áridos, onde a escassez de água e salinidade do solo são comuns. Entretanto, estudos sobre a tolerância de semente

8. Synergy between cadmium and zinc in bean plants cultivated in multi contaminated soils
ABSTRACT. Agricultural species are subjected to a variety of biotic and abiotic stresses, which are the main limitations to crop production. In this context, contamination by trace elements is characterized as an abiotic stress that represents an environmental problem. Due to the physical and chemical similarities between cadmium and zinc, these elements may

9. Inducible cellulase production from an organic solvent tolerant Bacillus sp. SV1 and evolutionary divergence of endoglucanase in different species of the genus Bacillus
Abstract Bacteria are important sources of cellulases with various industrial and biotechnological applications. In view of this, a non-hemolytic bacterial strain, tolerant to various environmental pollutants (heavy metals and organic solvents), showing high cellulolytic index (7.89) was isolated from cattle shed soil and identified as Bacillus sp. SV1 (99.2

10. Effect of herbicides in the oxidative stress in crop winter species
ABSTRACT Most herbicides applied in crop field, stay in the soil for a period, affecting next crop or even the plants using as green manure. Nowadays, the use of herbicides grow to increase productivity, mainly in the grain producing region north of Rio Grande do Sul state. The objective of this study was to evaluate the effects of herbicides fomesafen and s

11. Polyphasic characterization of bacteria obtained from upland rice cultivated in Cerrado soil
ABSTRACT This work aimed to characterize 20 isolates obtained from upland rice plants, based on phenotypic (morphology, enzymatic activity, inorganic phosphate solubilization, carbon source use, antagonism), genotypic assays (16S rRNA sequencing) and plant growth promotion. Results showed a great morphological, metabolic and genetic variability among bacteri

12. Physiological Responses to Hypoxia and Manganese in Eucalyptus Clones with Differential Tolerance to Vale do Rio Doce Shoot Dieback
ABSTRACT: Vale do Rio Doce shoot dieback (VRDSD) is an anomaly whose cause seems to be associated with hypoxic conditions and their consequences (excess Mn and Fe) triggered by elevation of the water table in areas with poor drainage. Different plants have distinct survival strategies under this form of stress. The objective of this study was to understand t
