Species of the genus are filamentous fungi commonly used in research, industry and agriculture. strains are prominent producers of cellulolytic and hemicellulolytic enzymes as well as being expression hosts; several other species such as might be exploited as biocontrol agents. A careful preparation of inocula, which consists mainly of conidia (asexual spores), is of immense importance. Conidia concentration is still mostly determined with the help of a hemocytometer; however, as a more accurate and time-saving alternative, absorbance can be used to estimate fungal spore counts. We established a spectrophotometric method for fast and reliable preparation of inocula by evaluating the effect of size, shape and pigmentation of the conidia at different wavelengths.
属的物种是在研究、工业和农业中常用的丝状真菌。 菌株是纤维素酶和半纤维素酶的主要生产者,也是表达宿主;其他一些物种,如 可能被用作生物防治剂。 精心制备接种物非常重要,接种物主要由分生孢子(无性孢子)组成。 分生孢子浓度仍然主要通过血球计数器来确定;但是,作为更准确和节省时间的替代方法,可以使用吸光度来估计真菌孢子的数量。 我们通过评估不同波长下分生孢子的大小、形状和色素沉着对吸光度的影响,建立了一种分光光度法来快速可靠地制备接种物。
