“…In several studies [27,32,[34][35][36][37][38][39][40][41], sugarcane bagasse has been used as a substrate for solid-state fermentation by A. niger to produce citric acid production (Table 3). After 216 h at 30 • C, A. niger strain DS1 produced a 2.2-fold higher level of citric acid on sugarcane bagasse (65% moisture) in a sucrose-containing medium supplemented with 4% methanol than if the strain was grown on the unsupplemented sugarcane bagasse-containing medium [34].…”

“…Citric acid production by A. niger ATCC 9142 on acid-treated sugarcane bagasse (75% moisture content) in a sucrose medium supplemented with 4% methanol was studied and was found to produce a low level of citric acid after 144 h at 30 • C [40]. Using solid-state fermentation of untreated sugarcane bagasse (65% moisture), A. niger strain MCCB0201 produced a very low level of citric acid after 120 h at 30 • C [41]. If the bagasse was treated with acid, urea or heat, citric acid production by the strain increased by 3.1-fold, 2.1-fold or 1.6-fold, respectively, after 120 h at 30 • C [41].…”

The ability of Aspergillus niger strains to support citric acid production using solid-state fermentation of agricultural processing coproducts was examined in this review. Citric acid has been shown to have a number of commercial applications in the food and beverage industries. The A. niger strains capable of elevated citric acid production are known to contain genetic mutations that stimulate overproduction of the organic acid likely involving citric acid cycle reactions. The agricultural processing coproducts previously examined for their ability to support citric acid production by A. niger solid-state fermentation include fruit processing wastes, sugarcane bagasse, starch vegetable processing wastes and cereal grain processing coproducts. A comparison of citric acid production by A. niger strains using solid-state fermentation demonstrated that certain agricultural processing coproducts were more effective in supporting a high level of acid synthesis. In particular, fruit processing wastes, such as apple pomace, banana peels, grape pomace and orange peels, supported high levels of citric acid by the fungal strains following solid-state fermentation. On the other hand, processing coproducts of cereal grains, such as brans and ethanol processing coproducts, supported low levels of citric acid production by the A. niger strains using solid-state fermentation. It appeared that the cereal processing coproducts provided less available sugar content to support citric acid production by the fungal strains. It was concluded that the level of citric acid produced by the A. niger strains during solid-state fermentation was dependent on the sugar content of the agricultural processing coproduct utilized.

“…It is possible to note that MAP (uncoated) and MAP Mix (without microorganism) also showed a slight pH decrease until the 3th day of incubation, with pH stabilized at around 5.5. However, the MAP Mix+A.niger granules showed a signi cant pH reduction from 7 to 3, which is associated with the ability of A. niger to produce acidity as organic acids [13,[22][23].…”

Fertilization is essential to provide suitable conditions for plant development and crop productivity, but the environmental cost of fertilizer production is a drawback for achieving a sustainable agriculture. Using unprocessed (raw) nutrient sources such as elemental sulfur (S0) and mineral oxides (ZnO, MnO, CuO) as fertilizers reduces the environmental impact, although they are not readily available to plants. Thus, we developed a polymeric coating material based on gelatinized starch loaded with S0 and oxides, and selected microorganisms – Aspergillus niger and Aciditiobacillus thiooxidans – aiming at a multi-nutrient fertilizer in which the biological components improve the solubility of the low reactive nutrient sources. The acidifying capacity of both microorganisms led to a synergic release and increased the availability of micronutrients and the elemental sulfur oxidation rate. For instance, the polymeric coating composition enabled a sulfate release of up to 76.4 and 71.3% for A. niger and A. thiooxidans, respectively. This innovative system can effectively supply nutrients to plants through the use of cheap and low reactivity nutrient sources with the advantage that it can be applied on currently used fertilizer granules, making easier the adoption by producers.

“…From the environmental perspective, an important advantage of SSC is the ability to use agro-industrial wastes as low-cost sources of carbon. A potential substrate for SSC is sugarcane (Saccharum officinarum L.) bagasse due to its properties and availability, being used for the production of valueadded bio-products, such as enzymes and organic acids (Soccol et al, 2008;Rodríguez-Zúñiga et al, 2011;Sharan et al, 2015;Dezam et al, 2017). Therefore, studies focusing on the development of bioprocess strategies for the solubilization of phosphate rock using sugarcane bagasse as a substrate for SSC could potentially contribute to obtain eco-friendly fertilizers for a more sustainable agriculture.…”

The objective of this work was to evaluate the solubilization of phosphorus from a phosphate rock by Aspergillus niger, under solid-state cultivation (SSC) in sugarcane (Saccharum officinarum) bagasse, by maximizing the efficiency of citric acid production. The phosphate rock (IPR) chosen for the study is a type of igneous rock with a very low phosphorus solubility, obtained from the Itafós company, in Arraias, in the state of Tocantins, Brazil. The rotatable central composite design (RCCD) was used as a statistical tool to evaluate the effect of the concentrations of the carbon source (sucrose) and of the IPR on the SSC medium as a strategy to improve P solubilization. In the process without the IPR, there was a citric acid production of up to 300 g per kilogram of substrate. The experiments in the RCCD showed that the addition of the IPR affected citric acid production, with values of solubilized P ranging from 1.44 to 2.72 g per kilogram of substrate and of solubilized P yield from 12.96 to 48.94%. The analysis of the solubilized P/sucrose ratio showed favorable conditions for P solubilization and citric acid production. The obtained solubilized P values are promising considering that the IPR has a very low solubilization, with only 8.6% P2O5. Overall, these findings could contribute to the development of biotechnological processes for producing eco-friendly phosphate fertilizers, as an alternative for a more sustainable agriculture.
