TEM micrographs of " C ." proptothecoides var. acidicola strain 124. (a) TEM micrograph of autospores fixed with glutaraldehyde, paraformaldehyde, and tannic acid. Note the different size of the two autospores. c = chloroplast, n = nucleus, m = mitochondrion. (b) Magnification of the cell wall structure. The arrow points at the trilaminar outer layer, the arrowhead at the granulo-fibrillar inner layer.
