Fig. 7From: Development of the thermophilic fungus Myceliophthora thermophila into glucoamylase hyperproduction system via the metabolic engineering using improved AsCas12a variantsTransmission electron micrographs of the M. thermophila strains. The MtGM12 mutant and MtWT strain were grown in minimal medium with 2% (w/v) starch as sole carbon source for 48 or 72Â h. Mycelia were collected and prepared for transmission electron microscopy. White arrows indicate endoplasmic reticulum. M, mitochondrion; N, nucleus; V, vacuole; S, secretion vesiclesBack to article page
