“…The highest ciliate mean abundance along the whole sampling period was found on RBC 2 biofilms (1.84 × 10 6 ciliates g -1 VS), while RBC 1 and RBC 3 showed similar densities (6.12 × 10 5 ciliates g -1 VS and 6.54 × 10 5 ciliates g -1 VS respectively). 55 ciliate species were identified in the three RBC stages, which was the higher number reported to date in RBCs (Hoag et al, 1980;Madoni and Ghetti, 1981;Kinner and Curds, 1987;Rivera et al, 1988;Kinner et al, 1989;Chung and Strom, 1991;Luna-Pabello et al, 1990.…”

A rotating biological contactor (RBC) system operating in a full-scale wastewater treatment plant has been described by several approaches accounting for performance, composition and structure of biofilms in three stages through biological wastewater treatment (RBC1, RBC 2, RBC 3). RBC biofilms were effective in removing the BOD loading from 13 g BOD5 d(-1) m(-2) in RBC 1 to 6 g BOD5 d(-1) m(-2) in RBC 3. Analysis of biofilm composition showed: i) the volatile solids were similar in the three RBCs (0.6 g m(-2) VS per g m(-2) of TS); ii) the protozoan and metazoan biocenosis was mainly made up of ciliated protozoa, which were most abundant in RBC 2 (1.84 x 10(6) ciliates g(-1) VS). Relationship between ciliate species and physical-chemical profile of the system by cluster analysis indicated that the species Acineria uncinata, Amphileptus punctatus, Cinetochilum margaritaceum and Holosticha mancoidea were associated with the best RBC performance; iii) the exopolymeric matrix of the three RBC biofilms was mainly constituted by proteins, although humic substances, polysaccharides, uronic acids and DNA were also found. Analysis of biofilm structure by confocal microscopy indicated changes in biofilm organisation with depth. Results have been brought together and a graphic representation of the composition and architecture of RBC biofilms is presented.

“…El aspecto taxonómico-ecológico ha sido abordado por varios autores entre ellos Rivera et al (1986Rivera et al ( , 1992 y Lugo et al (1998). Castro (1985), Moreno (1985) y Rivera et al (1988) registraron las especies de sistemas de tratamiento de aguas y Lugo et al (1991) refirieron las comunidades de protozoos indicadores de éste tipo de sistemas. Zumaquero-Ríos et al ( 2011) contribuyeron con datos de diversidad de varios taxa de protistas en el estado de Puebla.…”

Actualmente en México se han registrado 146 especies de protistas flagelados heterótrofos incluidas en los taxones Rhizaria, Stramenopiles y Excavata. Los grupos con la mayor riqueza de especies corresponden a parabasálidos, opalínidos, tripanosomátidos y bodónidos. Los géneros con el mayor número de especies son Trypanosoma, Trichomonas, Metadevescovina y Bodo y las especies de éste último han sido registradas en una diversidad de hábitats. Trypanosoma se ha documentado en 20 estados, correspondiendo al género con mayor distribución geográfica en la República Mexicana. Se concluye que el estudio de los flagelados heterótrofos es parcial, y es posible la descripción de nuevas especies, registro de hábitats y localidades geográficas.
