1. Comparison of the damaging effects of Meloidogyne incognita on a resistant and susceptible cultivar of cucumber
ABSTRACT In the present study, the damaging effects of six inoculum densities of Meloidogyne incognita were compared on a resistant (Long Green) and a highly susceptible (Mirage) cultivar of cucumber. All the inoculum densities of M. incognita resulted in significant reductions in growth and yield variables of both the cultivars over their controls. The redu

2. Incorporação de biomassa de fabáceas ao substrato de plantio para controle da podridão-de-escleródio (Sclerotium rolfsii) em cubiu (Solanum sessiliflorum)
RESUMO O cultivo do cubiu (Solanum sessiliflorum Dunal), no Amazonas, é limitado pela alta incidência da doença podridão-de-escleródio (Sclerotium rolfsii Sacc.) e a incorporação de material vegetal ao substrato de cultivo altera a microflora presente. O trabalho objetivou avaliar o potencial de controle da podridão-de-escleródio em cubiu por meio d

3. Meloidogyne javanica parasitism and its impacts on the vegetative parameters, physicochemical composition, and antioxidant potential of beet
Resumo: O objetivo deste trabalho foi avaliar o efeito da infestação por Meloidogyne javanica sobre o desenvolvimento vegetativo, as características nutricionais e o potencial antioxidante da beterraba (Beta vulgaris). A inoculação foi feita em plântulas de beterraba com 0, 1.000, 2.500, 5.000 e 10.000 ovos e prováveis juvenis de nematoide em segundo

4. Assessment of the nitrification process in a culture of pacific white shrimp, using artificial substrate and bacterial inoculum in a biofloc technology system (BFT)
RESUMO: Litopenaeus vannamei é o camarão marinho mais cultivado em todos os tipos de sistemas, incluindo o Sistema de Tecnologia de Bioflocos (BFT). Os bioflocos são formados por microorganismos, entre estes, bactérias autotróficas que são responsáveis pelo processo de nitrificação. Este estudo teve como objetivo identificar e promover o desenvolvi

5. Production of native arbuscular mycorrhizal fungi inoculum under different environmental conditions
Abstract In order to obtain an arbuscular mycorrhizal fungi (AMF) native inoculum from Sierra de Moa and determine the most appropriate conditions for its big scale production, four light and temperature combinations were tested in three plant species (Calophyllum antillanum, Talipariti elatum and Paspalum notatum). Growth and development parameters, as well

6. Collembola Community Structure as a Tool to Assess Land Use Effects on Soil Quality
ABSTRACT: Collembolan species are differently affected by soil tillage (conventional, minimum tillage, and no-tillage) and are known to modify plant growth. This study relies on the relationships between Collembola community structures and land use systems as a proxy for characterizing changes in soil quality. Thus, Collembola community structure (eco-morpho

7. Evaluation of bacterial diversity recovered from petroleum samples using different physical matrices
ABSTRACT Unraveling the microbial diversity and its complexity in petroleum reservoir environments has been a challenge throughout the years. Despite the techniques developed in order to improve methodologies involving DNA extraction from crude oil, microbial enrichments using different culture conditions can be applied as a way to increase the recovery of D

8. Carbazole degradation in the soil microcosm by tropical bacterial strains
In a previous study, three bacterial strains isolated from tropical hydrocarbon-contaminated soils and phylogenetically identified as Achromobacter sp. strain SL1, Pseudomonas sp. strain SL4 and Microbacterium esteraromaticum strain SL6 displayed angular dioxygenation and mineralization of carbazole in batch cultures. In this study, the ability of these isol

9. A new improved protocol for in vitro intratubular dentinal bacterial contamination for antimicrobial endodontic tests: standardization and validation by confocal laser scanning microscopy
Objectives To compare three methods of intratubular contamination that simulate endodontic infections using confocal laser scanning microscopy (CLSM). Material and Methods Two pre-existing models of dentinal contamination were used to induce intratubular infection (groups A and B). These methods were modified in an attempt to improve the model (group C).

10. Influence of Fusarium spp. isolate and inoculum density on resistance screening tests in onion
Fusarium basal rot (FBR), which is caused predominantly by Fusarium oxysporum and F. proliferatum, is the main limiting factor of onion crops. Resistant cultivars obtained in other countries do not behave as such in Argentina crop fields. The cultivars Antártica-INTA, Grano de Oro-Seminis, Valcatorce-INTA and TW-2007 (reported as tolerant) were tested with
