P.  aBio-based composite granules with simultaneous biocontrol and phosphorus fertilization rolesboutcomes from a lab-scale in vitro assessment.h[electronic resource]  c2022  aAbstract: The use of phosphate rocks as low-solubility phosphorus fertilizers has been promoted to reduce the environmental impacts of agriculture, but adequate nutrient uptake by plants depends on solubilization of the rock, driven by soil microorganisms. Here, investigation was made of the microbial solubilization of low-solubility phosphate rocks, together with simultaneous bioprotective action involving the biocontrol of microorganisms. The aim was to enhance function and value by delivering two effects using a single bio-based product, in accordance with the concept of a bioreactor-in-a-granule system. A composite structure was developed, based on a starch matrix, comprising a combination of Trichoderma asperelloides, as a biocontrol agent, and Aspergillus niger, as an acidulant. A significant increase of up to 150% in P solubilization was achieved, indicating the positive effect of the microorganism-composite interaction. In vitro assays showed that the ability of T. asperelloides to inhibit Fusarium oxysporum mycelial growth was maintained in the presence of A. niger. Moreover, the estimated cost of the composite granule (0.35 US$/kg of product on a dry basis) revealed competitive. The results indicated that the association of T. asperelloides and A. niger is an effective way to increase nutrient availability and to inhibit plant pathogens, opening up possibilities for the design of multifunctional bio-based fertilizer composites.  aBiofertilizers  aBiological control  aPhosphate minerals  astarch  aAbsorção de Nutrientes  aAspergillus Niger  aBiofertilizante  aControle Biológico  aFertilizante Fosfatado  aMicrorganismo  aRocha Fosfatada  aTrichoderma  aBio-based fertilizer  aBiocontrol  aBiofertilizer  aTrichoderma asperelloides1 aKLAIC, R.1 aBETTIOL, W.1 aOLIVEIRA, C.
