Comments 注释 This strain is recommended by ATCC for use in the tests described in ASTM Standard Test Method E979-91 where only the taxon is specified. This strain was recently re-named as Aspergillus brasiliensis. Use of impedance for preservative efficacy testing Morphology Colonies initially white or yellowish, mycelium growing rapidly producing a dense layer of erect smooth-stiped, conidiophores terminated by globose vesicles bearing phialides (uniseriate) or metulae with phialides (biseriate) which produce dry chains of conidia. Reverse pale to grayish or greenish yellow. Vesicles radiate, initially pale, becoming dark brown to black. Conidia spherical, mid-to-dark brown, highly roughened with ridges and blunt or pointed protuberances, (3-)4-5(-6) μm in diameter. Sporulation may be inhibited when grown in vessels with reduced gas exchange. Colonies may exhibit sectoring with areas of varying levels of sporulation. Use of freshly produced spores as inoculum should reduce sectoring.

生态分布
黑曲霉,广泛分布于土壤、空气和谷物上,可引起食物、谷物和果蔬的霉腐变质,有的可产生致癌性的黄曲霉毒素。
经济用途
黑曲霉是制酱、酿酒、制醋的主要菌种。是生产酶制剂(蛋白酶、淀粉酶、果胶酶)的菌种。 生产有机酸(如柠檬酸、葡萄糖酸等)。农业上用作生产糖化饲料的菌种。可用来测定锰、铜、钼、锌等微量元素和作为霉腐试验菌。干酪成熟中污染会使干酪表面变黑、变质,对奶油也会产生变色。
