This work aimed to obtain rheological parameters of a medium composed by sugarcane bagasse and wheat bran before and during the cultivation with Myceliophthora thermophila I-1D3b. A texture profile analysis (TPA) was performed and assays of compression and tensile strength were carried out and the parameters such as hardness, cohesiveness and springiness were determined. For the experiments of tensile strength, the fungus was cultivated in two discs of wheat bran separated by a definite void, which was filled by the aerial mycelium along the cultivation and the force required to take apart both discs was measured as a function of the cultivation time. Another tensile strength experiment was carried out in a block of sugarcane bagasse and wheat bran and the force required to disrupt the block was measured along the cultivation. Experiments of double compression before the cultivation were carried out moistening the samples well in advance of the experiment (15 days) and just before the experiment. Experiments of double compression during the cultivation were done with samples at different moisture contents and cultivation times, moistening the samples just before the experiment. The results showed that moistening the samples well before the experiment produced harder samples. A trend of decrease of the compression force was noticed with the increase of the cultivation time, indicating physical degradation of the solid material. The maximum breaking stress of the hyphaes and of the cultivated medium took place at 24 h of cultivation, which was coincident with the maximum respirometric activity of the fungus. This work brings new methods of determination of mechanical properties to the solid-state cultivation field and the determined parameters will be of help for modeling particle movement during the cultivation in different types of bioreactors.

这项工作旨在获得由嗜热毁丝霉培养之前和期间由甘蔗渣和麦麸组成的培养基的流变参数。I-1D3b。进行质地轮廓分析（TPA），并进行抗压强度和拉伸强度的测定，并确定诸如硬度，内聚性和弹性的参数。为了进行抗张强度实验，将真菌种植在两个麦麸圆盘中，小麦圆盘之间有一定的空隙，沿着培养过程由气生菌丝体填充，并测量了将两个圆盘分开所需的力时间。在一块甘蔗渣和麦麸中进行了另一项抗张强度试验，并在耕种过程中测量了破坏该块所需的力。在培养之前（15天）和即将进行实验之前，进行了在培养之前进行两次压缩的实验。在培养过程中用不同水分含量和培养时间的样品进行两次压缩实验，在实验前将样品润湿。结果表明，在实验之前充分润湿样品会产生较硬的样品。随着培养时间的增加，观察到压缩力降低的趋势，这表明固体材料的物理降解。菌丝和培养基的最大断裂应力发生在培养的24小时内，这与真菌的最大呼吸活性相吻合。
