Resumo: | Indolacetic acid (IAA) production was evaluated under in vitro conditions by five P-solubilizing fungi (PSF), identified as Aspergillus sp. and four P-solubilizing bacteria (PSB) of the Enterobacteriaceae family. The bacteria and fungus isolates were incubated in a liquid medium at 28ºC for two and four days, respectively. Moreover, two PSB isolates of the Enterobacteriaceae family (PSB 8 and PSB 56) were evaluated in relation to their ability to stimulate or inhibit spore germination and hyphal growth of two arbuscular mycorrhizal fungi (AMF) species under in vitro conditions. Two assays were carried out in Petri dishes with agar (0.8%), the first using the AMF Gigaspora margarita and the second with the AMF Scutellospora sp. The treatments were: inoculation of PSB 8; PSB 56 and uninoculated control. P-solubilizing isolates produced different amounts of IAA and most PSF isolates produced higher IAA than PSB. From the 18th day of incubation of Scutellospora sp., a significant increase in hyphal growth in the treatment inoculated with PSB 8 was observed. In contrast, PSB 56 inhibited the hyphal growth of Gigaspora margarita from the 24th day of incubation. |

Os isolados de bactéria e fungo foram incubados em meio líquido a 28ºC, por dois e quatro dias, respectivamente. Além disso, dois isolados de BSF da família Enterobacteriaceae (BSF 8 e BSF 56) foram avaliados quanto à capacidade de estimular ou inibir a germinação de esporos e o desenvolvimento micelial de duas espécies de fungos micorrízicos arbusculares (FMAs) in vitro. Foram instalados dois ensaios em placas de Petri, contendo agar-água (0,8%); um, utilizando o FMA Gigaspora margarita e o outro, com o FMA Scutellospora sp. Os tratamentos foram inoculação de BSF 8; BSF 56 e controle não-inoculado com BSF. Houve uma produção diferenciada de AIA pelos solubilizadores, destacando-se a maior produção pela maioria dos isolados fúngicos. A partir do 18º dia de incubação de Scutellospora sp., foi verificado um incremento significativo do comprimento de hifas no tratamento inoculado com BSF 8. Contrariamente, o crescimento micelial de G. margarita foi inibido pelo isolado BSF 56, a partir do 24º dia de incubação.Universidade Estadual De Maringá2007-12-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/49210.4025/actascibiolsci.v29i3.492Acta Scientiarum.
