“…El número de aislamientos obtenidos en este trabajo puede relacionarse con la elevada carga de material orgánico presente en el efluente, lo que favorece el crecimiento bacteriano. En trabajos previos de análisis de comunidades bacterianas en efluentes de mandioca, se ha reportado que la carga bacteriana es alta, lo que indica una gran diversidad de microorganismos [17,18].…”

El cultivo de mandioca en la Provincia de Misiones aporta la mayor parte de la producción a nivel nacional. Parte de la misma es destinada a la obtención de fécula, actividad que genera efluentes industriales con una elevada carga de materia orgánica y compuestos cianogénicos. Esto constituye una problemática a nivel ambiental y la biorremediación se presenta como una alternativa para la reducción de estos residuos, ya que se basa en la degradación del contaminante utilizando los microorganismos presentes en la matriz contaminada. El objetivo de este trabajo fue aislar microorganismos con capacidad para degradar almidón y tolerantes a cianuro a partir de efluentes de una industria almidonera. Fueron aisladas 93 cepas bacterianas y 15 de ellas fueron preseleccionadas mediante determinación cualitativa de actividad amilolítica. Utilizando el gen 16S rDNA para la identificación molecular, se determinó que algunos de estos aislamientos pertenecen a los géneros Pseudomonas, Acinetobacter y Proteus. Esas cepas se cultivaron en medio mínimo con distintas concentraciones cianuro y se logró determinar que una de ellas posee tanto la actividad amilolítica como la tolerancia a cianuro, ambas características deseables para biorremediación de efluentes de la industria almidonera.

“…This method limits the research on phytoplankton diversity to a certain extent. The emergence of high-throughput sequencing makes it possible to quickly and accurately obtain the composition of the microbial community in samples (Amao et al, 2019). The high-throughput sequencing of environmental samples has the potential to detect rare, small and fragile species, and can be used to monitor and quantify biodiversity (Gao et al, 2020).…”

As an important regulator of ecosystem functions in river systems, microeukaryotes play an important role in energy and material conversion, yet little is known about the shift along a lentic-lotic continuum. In this study, the 18S rRNA genes sequencing was used to identify the microeukaryotic communities at 82 sites along a lentic-lotic continuum with the aim of understanding the impact of upstream inlet river on microeukaryotic communities in Baiyang Lake (BYD) and its downstream. Our results showed that the upstream inlet river affected the diversity and community composition of microeukaryotes in BYD and downstream rivers, and environmental variables greatly affected the composition of microeukaryotic community. The community composition in BYD had lower variabilities. Co-occurrence network analysis revealed that the network was non-random and clearly parsed into three modules, and different modules were relatively more abundant to a particular area. As keystone taxa, some nodes of the upstream microeukaryotic network played an important role in structuring network and maintaining the stability of the ecosystem. In BYD and downstream, the microeukaryotic network was highly fragmented, and the loss of keystone taxa would have an adverse impact on the integrity and function of the microeukaryotic community. Microeukaryotes had strong tendencies to co-occur, which may contribute to the stability and resilience of microeukaryotic communities. Overall, these findings extend the current understanding of the diversity and community composition of microeukaryotic along a lentic-lotic continuum.
