“…as the more often described genera (Silva Filho et al, 2002;Morales et al, 2007). Inoculation with phosphatesolubilizing fungi enhanced plant growth and increased P uptake by the plants, both under greenhouse and field conditions (Asea et al, 1988;Whitelaw, 2000;Wakelin et al, 2004;Morales et al, 2007).…”

A study was performed to determine the effect of arbuscular mycorrhizal (AM) fungal inoculation, using a locally isolated Claroideoglomus claroideum (Gc) ecotype, on the seedling development of chilean pepper plants, and to select an appropriate growth substrate. The first experiment consisted of two stages: (i) a seedling production stage of pepper plants were germinated and grown, inoculated or not with C. claroideum; and (ii) a seedling transplanting stage, in which seedlings were transplanted to a wider capacity containers, using the same substrates as in the seedling production stage. These were inoculated or not with C. claroideum and/or Penicillium albidum (Pa). A soil mixture was selected as the target substrate for further studies. A second experiment was then carried out and three new phosphate-solubilizing Penicillium that is, Penicillium frequentans, Penicillium jensenii and Penicillium restrictum, were incorporated as inoculation variables, in addition to the already tested P. albidum, inoculated either alone or in co-inoculation with C. claroideum. After 28 weeks, plants were harvested and fruit number, weight, and length were recorded. A synergistic interaction between C. claroideum and P. albidum to improve fruit weight and phosphorous (P) concentration was evidenced, suggesting a sustainable alternative for chilean pepper production.

“…The improvement in the growth of plants inoculated with saprobe fungi has been reported for several plant species, and has been attributed to the production of plant growth promoting substances and antimicrobial compounds (Arriagada et al, 2009b;Arriagada et al, 2010). In addition to, several strains of the genera Penicillium fungi have been described as efficient P-dissolving fungi (Silva Filho et al, 2002).…”

In this study we evaluated the initial plant growth and some biochemical changes produced in rizhosphere soil of blueberry (Vaccinium corymbosum L.) cv. 'Elliot' plantlets obtained from in vitro culture and inoculated with six arbuscular mycorrhizal (AM) fungi strains (Gigaspora rosea; Glomus claroideum; G. deserticola; G. viscosum; G. intraradices and G. constrictum) and five saprobe fungi (Coriolopsis rigida; Phanerochaete chrysosporium; Trametes versicolor; Trichoderma harzianum and Penicillium chrysogenum). Our results showed a significant "like" AM root colonization (25-46%), highlighting the treatment co-inoculated with G. rosea + P chrysosporium or C. rigida; G. intraradices + C. rigida; G. viscosum + P chrysosporium, but this root colonization was morphologically atypical, and dominated by interstitial hyphae, without develop of other typical AM structures. Furthermore, significant increase in the shoot and root growth of the plantlets inoculated with G. viscosum + P chrysosporium, and G. intraradices + C. rigida were observed. On the other hand, G. claroideum + T. versicolor showed the high increase in the dehydrogenase enzyme activity, while inoculation with G. claroideum alone showed the greatest ß-glucosidase activity. These results suggest that the interaction of AM symbionts together with saprobe fungi could be a biological alternative to promote the growth of micro-propagated blueberry plantlets in their early growth stages.

-(In vitro solubilization of phosphates by Aspergillus brasiliensis Varga, Frisvad & Samson in the presence of carbon sources). Phosphate-solubilizing fungi play an important role in the availability of phosphorus for plants, as they are capable of reverting insoluble phosphates into soluble forms. However, the solubilization of phosphates may be influenced by the growth of the fungus, which depends on the availability of carbon. The aim of this study was to evaluate the capacity and potential in vitro solubilization of phosphate sources by Aspergillus brasiliensis in the presence of conventional (starch, glucose, and sucrose) and alternative (co-products of winemaking) carbon sources, in the region of Vale do São Francisco, Petrolina, Pernambuco State, Brazil. All carbon sources were assimilated by the specimens, although providing different responses. The co-products of winemaking stimulated fungal growth, providing greater solubilization of phosphates. It is concluded that the co-products of winemaking can be used in agriculture as a viable alternative and a less costly way to produce inoculum of solubilizing fungi and stimulate the growth of indigenous fungi in order to optimize the availability of non-renewable sources. Keywords: filamentous fungi, grape bagasse, phosphorus RESUMO -(Solubilização de fosfatos in vitro por Aspergillus brasiliensis Varga, Frisvad & Samson na presença de fontes de carbono). Os fungos solubilizadores de fosfatos desempenham importante papel na disponibilização de fósforo para as plantas, pois apresentam capacidade de reverter fosfatos insolúveis em formas solúveis. No entanto, a solubilização de fosfatos pode ser influenciada pelo crescimento do fungo, que depende da disponibilidade da fonte de carbono. O objetivo deste trabalho foi avaliar a capacidade e o potencial de solubilização de fontes de fosfato in vitro por Aspergillus brasiliensis na presença de fontes de carbono convencionais (amido, glicose e sacarose) e alternativas (coprodutos da vinificação), na região do Vale do São Francisco, Petrolina, PE, Brasil. Todas as fontes de carbono foram assimiladas pelos espécimes, proporcionando diferentes respostas. Os coprodutos da vinificação estimularam mais o crescimento fúngico, proporcionando maior solubilização dos fosfatos. Conclui-se que os coprodutos da vinificação podem ser utilizados na agricultura como alternativa viável e de menor custo para produzir inóculo de fungos solubilizadores e estimular o crescimento de fungos autóctones, visando a otimização na disponibilização de fontes não renováveis.
