Ultrastructural alterations in Phacus brachykentron (Euglenophyta) due to excess of organic matter in the culture medium [PDF]

open access: yesEcotoxicology and Environmental Safety, 2014
Morphological and ultrastructural changes induced by exposure to excess of organic matter were analyzed in Phacus brachykentron (Pochm.). The cells were isolated from sites in Matanza River, Buenos Aires, Argentina, which have a high degree of organic matter contamination coming from waste waters discharges of the meat industry.

Nuclear cytology of Phacus Dujardin.

open access: yesCYTOLOGIA, 1989
Karyological investigations accomplished on sixteen local isolates of Phacus revealed the structure and pattern of mitotic division of nuclei to be atypical. The chromosome numbers ranged from n=10 in P. cylindrus to n=226±8 in P. longicauda, representing the widest range of chromosome numbers reported so far for euglenoid flagellates.
