1. Slow sand filtration eradicates eucalypt clonal nursery plant pathogens from recycled irrigation water in Brazil
Contaminated irrigation water constitutes one of the main sources of plant pathogens that can cause disease and lead to potentially significant production losses in forest nurseries. Recycling of contaminated irrigation water increases the risk of spreading diseases. The objective of this study was to evaluate a simple slow sand filtration treatment of irrig

2. The nematicidal effect of some bacterial biofertilizers on Meloidogyne incognita in sandy soil
In a greenhouse experiment, the nematicidal effect of some bacterial biofertilizers including the nitrogen fixing bacteria (NFB) Paenibacillus polymyxa (four strains), the phosphate solubilizing bacteria (PSB) Bacillus megaterium (three strains) and the potassium solubilizing bacteria (KSB) B. circulans (three strains) were evaluated individually on tomato p

3. Dosimetria esporular: Bacillus subtilis TKJ6312 como biossensor de radiação solar biologicamente ativa
Since 2000, spore dosimetry and spectral photometry have been performed in parallel at the Southern Space Observatory, São Martinho da Serra (Southern Brazil). A comparative study involving data from Punta Arenas - Chile (53.2º S), São Martinho da Serra (29.5º S), Padang - Indonesia (0.9ºS), Brussels - Belgium (50.9º N) and Kiyotake - Japan (31.9º N)

4. Rhizospheric microorganisms and arbuscular mycorrhiza in soil from a petrochemical waste landfarming system. / Microbiota RizosfÃrica e Micorriza Arbuscular em Solo de "Landfarming" de ResÃduos PetroquÃmicos.
In the petroleum industrialization a great volume of different toxic residues is generated. Because of these waste environmental hazards they need to be adequately treated before final disposition in the environment. These wastes are usually treated by landfarming systems, but this technique has only relative success, since it doesn t completely remove all c

5. Estudos de Bacillus thuringiensis Berliner visando ao controle de Spodoptera frugiperda (J.E.Smith). / Bacillus thuringiensis berliner research applied for the control of Spodoptera frugiperda (J. E. Smith).
From 24 soil samples about 461 bacterial colonies have been isolated, and 190 were identified as Bacillus thuringiensis (Bt). The relation between soil chemical characteristics and the presence of this pathogen may be expressed by the equation iBt = -0,4 + 0,6Ca + 0,07Cu + 0,009Fe - 0,53Mg -0,12Mn + 1,26Zn. Among 83 Bt isolates assayed against Spodoptera fru

6. Pathogenicity factors of Bacillus spp isolated from UHT milk / Estudo de fatores de patogenicidade de Bacillus spp isolado em leite UHT
O leite produzido a ultra alta temperatura denominado oficiamente como UHT é o leite de maior aceitação no mercado consumidor brasileiro. Com a finalidade de ampliar o conhecimento sobre a segurança microbiológica do leite UHT, objetivou-se estudar tanto os Bacillus spp, que vêm sendo relatados como contaminantes do leite UHT no Brasil, como os eventua

Black, S. H. (The University of Michigan, Ann Arbor) and Philipp Gerhardt. Permeability of bacterial spores. I. Characterization of glucose uptake. J. Bacteriol. 82:743–749. 1961.—The total uptake of glucose by masses of clean, dormant spores was measured to assess their permeability. After correction for intercellular space, packed spores of Bacillus ce
