1. Phonolite associated with organic compound and potassium solubilizing bacteria in tomato cultivation
ABSTRACT The use of rock dust in Brazil has been studied and encouraged to reduce the Brazilian dependence on the foreign market for chemical fertilizers and as an alternative to organic agriculture. The objective of this research was to evaluate the effects of using phonolite rock powder and organic compound, associated with inoculation with the potassium s

2. Micobiota produtora de fitase isolada de solo e serapilheira do Bioma Cerrado
Resumo Grande parte dos solos agricultáveis brasileiros apresenta deficiência de P, em função da maior parte deste elemento estar indisponível para a absorção pelas plantas. Neste contexto, a habilidade dos fungos filamentosos em solubilizar o P de várias fontes, sejam estas, insolúveis, orgânicas e/ou inorgânicas, tem sido considerada uma caracte

3. Maize yields and carbon pools in response to poultry litter, rock phosphate and P-solubilizing microorganisms
ABSTRACT: The acid release of phosphates from rock phosphates (RP) and the retention of ammonium by inorganic phosphates have been studied separately in composting; however, there is a gap in the knowledge of combined application of RP with organic residues and microorganisms. The objectives were to evaluate the combined application of fresh poultry litter (

4. 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

5. Binary systems of Brij® surfactants with Pluronic® F127 as griseofulvin carrier
The binary mixtures of Brij® surfactant and Pluronic® F127 were studied as carriers of griseofulvin. The F127 systems and Brij® 78 (C18H37E20), Brij® 98 (C18H35E20) and Brij® 700 (C18H37E100) were prepared in the proportions 10/90, 30/70, 50/50 and 70/30, respectively. The characterizations were carried out by tube inversion, rheology, particle size, an

6. Comparing Methods for Extracting Heavy Metals from Histosols for Establishing Quality Reference Values
ABSTRACT The diversity of methods for heavy metal extraction from soils complicates comparison of results used by environmental agencies to establish quality reference values. The aim of this study was to evaluate three soil digestion methods regarding the solubilizing capacity of Ba, Cr, Cu, Fe, Mn, Ni, Pb and Zn, and to propose a standard method to establi

7. COCRISTAIS: UMA ESTRATÉGIA PROMISSORA NA ÁREA FARMACÊUTICA
Pharmaceutical cocrystals have emerged as a useful strategy to improve the aqueous solubility of poorly water soluble drugs by aiming to enhance their oral absorption and bioavailability. Aqueous cocrystal solubility can be orders of magnitude higher than that of the constituent drug and this solubility advantage can be fine-tuned based on environmental cond

8. Isolation and identification by 16S rRNA sequence analysis of plant growth-promoting azospirilla from the rhizosphere of wheat
ABSTRACT The main objective of the present study was to isolate phytohormone-producing, phosphate-solubilizing strains of Azospirillum from wheat to be used as inoculants for plant growth promotion. Five Azospirillum strains were isolated from the rhizosphere of field-grown wheat (Triticum aestivum L.), and it was confirmed by BOX-polymerase chain reaction (

9. BIODECOMPOSITION OF JORDAN PHOSPHORITE BY PHOSPHATE-SOLUBILIZING FUNGI
Abstract The bio-solubilization of Jordan phosphorite by the phosphate-solubilizing fungus Aspergillus niger has been investigated. The effect of the phosphate concentration in the liquid medium, the duration of biodecomposition, titratable acidity and the effect of preliminary mechanical activation on the process of dissolution have been studied. The invest

10. Poly R decolorization and APPL production by Streptomyces violaceoruber and Streptomyces spiroverticillatus
Two mesophilic streptomycetes (S. violaceoruber and S. spiroverticillatus) were selected to study their Poly R-478 decolorization ability and lignocellulose solubilizing activity. Both strains were able to degrade Poly R-478 dye and ferulic acid during growth on a minimal salts medium. The Poly R-478 decolorizing activities of both strains were induced by ad

11. Dissolving mechanism of strain P17 on insoluble phosphorus of yellow-brown soil
Strain P17 was a bacterial strain identified as Bacillus megaterium isolated from ground accumulating phosphate rock powder. The fermentation broth of strain P17 and the yellow-brown soil from Nanjing Agricultural University garden were collected to conduct this study. The simulation of fixed insoluble phosphorous forms after applying calcium superphosphate

12. Production of humic substances through coal-solubilizing bacteria
In this paper, the production of humic substances (HS) through the bacterial solubilization of low rank coal (LRC) was evaluated. The evaluation was carried out by 19 bacterial strains isolated in microenvironments with high contents of coal wastes. The biotransformed LRC and the HS produced were quantified in vitro in a liquid growth medium. The humic acids
