| description |
Background and aims: Algae and Cyanobacteria species that grow in contaminated sites can accumulate high concentrations of heavy metals. In this work it was proposed to a) characterize the community of algae and Cyanobacteria and b) evaluate the effect of lead (Pb) on the composition of algae present in the rhizosphere of plants capable to accumulate Pb in Córdoba province.
M&M: Soil samples were taken from the rhizosphere of Sorghum halepense, Bidens pilosa and Tagetes minuta at sites with different levels of Pb. In the laboratory, the soil was sown in capsules with sterilized Watanabe medium. The cultures grew 9 weeks. The algae and Cyanobacteria were identified over the time and the final relative frequency analyzed.
Results: In contaminated soils, 24 species of Cyanobacteria, Chloroplastida and Xanthophyceae were identified. The heterocytous cyanobacteria Cylindrospermum muscicola, Nostoc commune and Calothrix clavata registered a relative mean frequency (between 21 and 60%). Trebouxia parmeliae (Chloroplastida) and Vaucheria sp. (Xanthophyceae) were present in soils with the highest level of Pb. Most of the species were concentrated in the lowest levels of Pb.
Conclusions: A negative effect of Pb on the species richness of algae and Cyanobacteria was observed in the rhizosphere of the evaluated plants. Based on the composition of the community of algae and Cyanobacteria in the soil, two groups are determined and could be considered tolerant and non-tolerant communities of Pb contamination. |

Introducción y objetivos: Las especies de algas y Cyanobacteria que crecen en sitios contaminados pueden acumular altas concentraciones de metales pesados. En este trabajo se propuso a) caracterizar la comunidad de algas y Cyanobacteria y b) evaluar el efecto del plomo (Pb) sobre la composición de algas presentes en la rizosfera de plantas capaces de acumular Pb en la provincia de Córdoba. M&M: Se tomaron muestras de suelo de la rizosfera de Sorghum halepense, Bidens pilosa y Tagetes minuta en sitios con diferentes niveles de Pb. En el laboratorio, el suelo se sembró en cápsulas con medio de Watanabe esterilizado. Los cultivos crecieron 9 semanas. Se identificó en el tiempo y analizó la frecuencia relativa final de las algas y Cyanobacteria. Resultados: En suelos contaminados se identificaron 24 especies de Cyanobacteria, Chloroplastida y Xanthophyceae. Las Cyanobacteria con heterocitos Cylindrospermum muscicola, Nostoc commune y Calothrix clavata registraron una frecuencia media relativa (entre 21 y 60%). Trebouxia parmeliae (Chloroplastida) y Vaucheria sp. (Xanthophyceae) estuvieron presentes en los suelos con mayor nivel de Pb. La mayor parte de las especies se concentraron en los niveles más bajos de Pb. Conclusiones: Se observó un efecto negativo del Pb sobre la riqueza de especies de algas y Cyanobacteria en la rizosfera de las plantas evaluadas. En base a la composición de la comunidad de algas y Cyanobacteria del suelo se determinan dos grandes grupos que podrían ser considerados como comunidades tolerantes y no tolerantes a la contaminación de Pb.
