1. The use of Arthrospira platensis in rearing Nile tilapia (Oreochromis niloticus) in salt water
RESUMO A tilápia do Nilo (Oreochromis niloticus) é uma espécie eurialiana e em sistemas marinhos é capaz de fornecer proteína animal onde a água doce é escassa. Com isso, torna-se imprescindível o gerenciamento adequado da água para manutenção da sustentabilidade, e o uso do sistema de recirculação de água salgada seria vantajoso para o atual m

3. Impact of phosphate solubilizing bacteria on wheat (Triticum aestivum ) in the presence of pesticides
Resumo Três bactérias solubilizantes de fosfato foram isoladas e identificadas por seqüenciamento de rRNA 16S como Pseudomonas putida, Pseudomonas sp e Pseudomonas fulva. As estirpes foram submetidas a testes bioquímicos de plantas e todos os atributos PGPR foram verificados na presença de pesticidas (clorpirifos e piriproxifeno). O índice de solubili

4. Isolation and prospection of diazotrophic rhizobacteria associated with sugarcane under organic management
Abstract Microorganisms associated with organic management are essential in nutrient transformation and release for plant use. The present study aimed to isolate, identify and characterize plant growth promoting diazotrophic rhizobacteria associated with sugarcane under organic management. Rhizospheres of organic sugarcane varieties IAC 911099 and CTC4 were

5. Bacterial selection for biological control of plant disease: criterion determination and validation
Abstract This study aimed to evaluate the biocontrol potential of bacteria isolated from different plant species and soils. The production of compounds related to phytopathogen biocontrol and/or promotion of plant growth in bacterial isolates was evaluated by measuring the production of antimicrobial compounds (ammonia and antibiosis) and hydrolytic enzymes

6. Alleviation of salt stress by halotolerant and halophilic plant growth-promoting bacteria in wheat (Triticum aestivum)
ABSTRACT In the current study, 18 halotolerant and halophilic bacteria have been investigated for their plant growth promoting abilities in vitro and in a hydroponic culture. The bacterial strains have been investigated for ammonia, indole-3-acetic acid and 1-aminocyclopropane-1-carboxylate-deaminase production, phosphate solubilisation and nitrogen fixation

7. Soil bacteria showing a potential of chlorpyrifos degradation and plant growth enhancement
ABSTRACT Background: Since 1960s, the organophosphate pesticide chlorpyrifos has been widely used for the purpose of pest control. However, given its persistence and toxicity towards life forms, the elimination of chlorpyrifos from contaminated sites has become an urgent issue. For this process bioremediation is the method of choice. Results: Two bacterial

8. Occurrence of Hirudinea species in a post urban reach of a Patagonian mountain stream
Temporal (May 2005 to February 2006) and habitat distribution (pools and riffles) of Hirudinea species was analyzed at a post urban reach from Esquel stream (Chubut province, Patagonia, Argentina). Site was located 5.7 km downstream a Waste Treatment Plant. Mean values of nutrients: ammonia, nitrates and soluble reactive phosphate, as well water conductivity

9. Characterization of Rhizobacteria from field grown Genetically Modified (GM) and non-GM maizes
This study was done to examine the rhizobacteria from field grown Genetically Modified (GM) maize and its non-GM counterpart. Rhizospheric soil samples were collected at 30 days after sowing (DAS) and at post-harvest from two experimental fields in Gauteng, South Africa. Total rhizobacteria (cfu/g) in GM and non-GM soil samples was not significantly differen

10. Modeling temporal variations of Gracilaria Greville and Hypnea J.V. Lamouroux (Rhodophyta) assemblages on a midlittoral reef platform at Piedade Beach, Pernambuco State, Brazil
The diversity of algal banks composed of species out the genera Gracilaria Greville and Hypnea J.V. Lamouroux have been impacted by commercial exploitation and coastal eutrophication. The present study sought to construct dynamic models based on algal physiology to simulate seasonal variations in the biomasses of Gracilaria and Hypnea an intertidal reef at P

11. Solubilização de fosfato por fungos do solo e eficiência de sua inoculação em caupi e milho / Phosphate solubilization by soil fungi and their efficiency in corn and cowpea inoculation
The process of biological nitrogen fixation in leguminous is achieved by bacteria forming nodules possessing the nitrogenase enzyme that are able to catalyze the reduction of molecular nitrogen to ammonia which is assimilated by the plants. Despite the high diversity of the Kingdom Fungi, reports on the solubilization on phosphates by fungi have been restric

12. Tratamento de esgoto sanitário pelo sistema zona de raízes utilizando plantas de bambu / Sewage treatment by root zone system using bamboo plants.
This study aimed to evaluate the efficiency of three species of bamboo (Guadua angustifolia, Phyllostachys aurea and Phyllostachys bambusoides) in the sanitary sewage treatment, with a vertically downward sub-surface flow root zone system, in Goiânia, GO, Brazil. Sewage from a university was applied to asbestos cement water tanks with 1,000 liters volume ca
