1884 Jrnl. Royal Microsc. Soc. 4 108 The immotile reproductive cells, which are formed directly without any true process of cell-formation, he [sc. N. Wille] calls ‘akinetes’; while to those formed asexually by true cell-formation he gives the term ‘aplanospores’.
1902 Encycl. Brit. XXV. 267/1 Akinetes are ordinary thallus cells, which on account of their acquisition of a thick wall are capable of surviving unfavourable conditions.
1986 M. Kogut tr. H. G. Schlegel Gen. Microbiol. iii. 128 Akinetes are ‘survival’ forms. They are recognised by their size, intense pigmentation, and thick cell walls.
2011 Trends in Microbiol. 19 281/1 Carbon limitation is also linked to the induction of akinete formation in some cyanobacteria.
