“…This is the case with phosphate solubilizing microorganisms (PSM) (Sahu and Jana, 2000;Whitelaw, 2000;Galindo et al, 2011;Paiva-Coutinho et al, 2012). There have been various reports on the dissolution of RP with individual inoculates (of just one species), but little is known about the effectiveness of microbial consortia (Xiao et al, 2008;Oliveira et al, 2009;Saber et al, 2009;Singh and Reddy, 2011). Additionally, existing reports on the subject have focused on one particular type of RP, which has limited the results to very specific effects (Singh and Reddy, 2011;Habte and Osorio, 2012;Xuan Yu et al, 2012).…”

The low availability of phosphorus (P) in the soil and the high cost of P fertilization are factors that limit agricultural productivity. A biotechnological alternative for to handle this problem is to use soil microorganisms capable of dissolving rock phosphate (RP), thus improving its effectiveness as a P fertilizer. This study was carried out with the objective of determining the effectiveness of Aspergillus niger -As-, Penicillium sp. -Pn-, Bacillus sp -B-. and an unidentified actinomycete -At-in the in vitro dissolution of two partially acidulated rock phosphates. The treatments consisted of 2x16 factorial arrangement [2 levels of RP: either Boyaca RP or Norte de Santander RP; 16 levels of inoculum: an uninoculated control, individual inoculations (with As, Pn, B, At), dual inoculations (AsPn, AsB, AsAt, PnB, PnAt, BAt), triple inoculations (AsPnB, AsPnAt, AsBAt, PnBAt), and quadruple inoculation (AsPnBAt)]. Each treatment was replicated three times. It was found that the microbial effectiveness in the in vitro dissolution of RP depended on the type of RP, the composition of the inoculum used and the interaction of both factors. The best results were obtained with the Norte de Santander RP and A. niger used alone. When this fungus combined with the other microorganisms, its capacity to dissolve RP was significantly reduced.

RESUMENLa baja disponibilidad de fósforo (P) en el suelo y el costo de la fertilización fosfórica son limitantes para la productividad agrícola. Una alternativa biotecnológica para manejar este problema es mediante el uso de microorganismos del suelo capaces de disolver rocas fosfóricas (RP) y así mejorar su efectividad como fertilizante fosfórico. Con este fin se realizó un ensayo para determinar la efectividad microbial en la disolución in vitro de dos RP (Norte de Santander y Boyacá) parcialmente aciduladas. Los tratamientos consistieron en un arreglo factorial 2x16 [2 niveles de RP: Boyacá o Norte de Santander; 16 niveles de inóculo: Un control no inoculado, inóculos individuales (Aspergillus niger -As-, Penicillium sp. -Pn-, Bacillus sp. -B-, y un actinomiceto no identificado -At-), inóculos dobles (AsPn, AsB, AsAt, PnB, PnAt, BAt), inóculos triples (AsPnB, AsPnAt, AsBAt, PnBAt), e inóculos cuádruples (AsPnBAt)]. Cada tratamiento tuvo tres replicas. La efectividad en la disolución in vitro de RP fue dependiente del tipo de RP, tipo de inóculo y la interacción de ambos factores, teniendo mejores resultados con la RP del Norte de Santander y A. niger sólo. Cuando este hongo se combinó con otros microorganismos su capacidad para disolver RP se redujo significativamente.

Phosphorus (P) is second largest limiting element for plant growth. The phosphate rock which is used in the manufacture of P fertilizers is nonrenewable resource. We have to address to future shortages for sustainable crop production in India. At global level, India ranks as second largest wheat producing nation and contributing approximately 11.9% to the world wheat production from about 12% of global area (USDA 2010). One of the major constraints in boosting up the wheat production is the unbalanced use of plant nutrients, particularly P and K. Average P uptake of wheat is about 3.8 kg P/t of grains (Timsina and Connor 2001). P recovery by wheat from fertilizers is quite low i.e. 15-20% of the applied P is recovered by wheat while the remaining P is fixed as insoluble P fractions in soils (Rodríguez and Fraga 1999). Only 0.1% of the total P exists in a soluble form available for plant uptake because of its fixation into an unavailable form. Increasing prices of P-fertilizers in developing countries like India and high fixation of P in soil have led to the search for sustainable way of P nutrition of crops. In this regards phosphate-solubilizing microorganisms (PSM) have been seen as the best eco-friendly means for P nutrition of crops.A number of bacteria (Bacillus spp., Pseudomonas spp., Burkholderia spp.) and fungi (Aspergillus spp., Penicillium spp.) are known to increase availability of P to plants and benefit plant growth either by mineralization of organic phosphate or by solubilisation of insoluble inorganic phosphates in soils through the production of organic acids (Rodríguez and Fraga 1999, Saber et al. 2009, Saxena et al. 2014 ABSTRACTPhosphorus (P) availability limits crop growth in most of cultivable soils in north-west India. The beneficial rhizosphere microorganisms such as phosphate-solubilising fungi (PSF) were found to increase P availability in soil and improve crop yields. In view of this, field experiments were conducted during 2009-2011 to evaluate the effect of seed inoculation with PSF (Penicillium bilaii) at different rates of fertilizer P on P content in leaves and grain yield of irrigated wheat in India. The soil was low in Olsen P at the Bathinda site and medium at the Ludhiana site. In no-P treatment, PSF significantly increased grain yield by 12.6% over non-inoculated control. The effect of PSF on grain yield was generally more pronounced in a soil with low Olsen-P compared to medium Olsen-P level. Inoculation of PSF along with 50% P fertilizer increased wheat yield equivalent to 100% P with no PSF. Spike density was significantly higher in PSF + 50% P than all the other treatments. There is need to study a long-term effect of Penicillium bilaii on P-fertilizer saving in wheat on soils varying in P availability, pH and P fixation capacity for different wheat-based cropping systems.

-(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.
