The objective of this work was to evaluate the mycelial growth of the Coprinus comatus strain CCO 01/01 in culture based on organic residues of Saccharum officinarum (sugarcane bagasse), Citrus sinensis (orange bagasse), Ananas comosus (pineapple residues) and Musa sp. (banana leaf), supplemented with wheat bran in the proportions of 0, 10 and 20%, kept at 27 degrees C. The mycelial growth of C. comatus was evaluated daily by measurement of the diameter of the colony during seven days of incubation. The banana leaf was considered the best residue for the cultivation of the C. comatus even without supplementation, meaning lower production costs. The supplementation of pineapple residues with 10% of wheat bran favored fungi growth. Sugar-cane bagasse was suitable for the growth of the C. comatus provided it is enriched with wheat bran. The orange bagasse, without pH correction, was not appropriate for the mycelial growth of C. comatus.

The objective of this study was to evaluate the effect of organic fertilizers (urban solid waste and swine manure) as a source of nutrients and residue from bauxite processing as a corrective of soil acidity, in area cultivated with sugar cane irrigated with potable water and served in the availability of phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S) levels in the soil and plants. For this experiment was carried out in pots, using a Alfisol, assessing the availability of the elements in the 0-20 cm layer and the concentration of these nutrients in the leaves of sugarcane. The data showed that the residues increased the concentrations of Ca and Mg in soil, as the concentration of K was not changed and S was not detected, due to the low concentration in the soil. In the leave +1 of sugarcane the residue of bauxite increased levels of N, P, K, Ca and Mg (15.68, 1.73, 10.43, 3.50 and 1.08 g kg-1, respectively). The application of urban solid waste and swine manure also increased the levels of N, K and Ca (11.56, 9.18 and 2.81 g kg-1, respectively). The quality of irrigation water did not alter the availability of P, K, Ca, Mg and S in the soil as well as the levels of these macronutrients in the plant.
