Última Monitoring and spatial distribution of heterotrophic bacteria and fecal coliforms in the Rodrigo de Freitas Lagoon, Rio de Janeiro, Brazil BABT Lutterbach,Márcia T. S.; Vazquez,Joselito Cabral; Pinet,Jorge A.; Andreata,José V.; Silva,Alexandre Carlos da. The distribution of heterothrophic bacteria and fecal coliforms was monitored at four sampling stations located near the shore of the Rodrigo de Freitas Lagoon, in the city of Rio de Janeiro, Brazil. Water samples were collected, monthly from October 1994 through September 1998. The highest heterothrophic count (6.5x10 7 CFU/100mL) was recorded at stations 2 and 4 during August 1998 and the lowest (10 ³ CFU/100 mL) at station 3 during February 1995. With respect to fecal coliforms, the highest and lowest counts were 1.6x10 5 coliforms/100mL at station 3 during March 1997 and <1 coliform/100mL at all the stations during February 1995 and September 1997 as well as station 3 during February 1998. The data indicated a percentage increase of the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Fecal coliforms; Heterotrophic bacteria; Rodrigo de Freitas Lagoon; Monitoring. Ano: 2001 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132001000100002 Heterotrophic bacteria abundances in Rodrigo de Freitas Lagoon (Rio de Janeiro, Brazil) BJM Gonzalez,Alessandra M.; Paranhos,Rodolfo; Lutterbach,Márcia S.. The Rodrigo de Freitas Lagoon (RJ, Brazil) is an important coastal ecosystem that has been submitted to an accelerated degradation process. The aim of this work was to determine the abundance and the spatial distribution of total heterotrophic (by flow cytometry) and cultivated bacteria ("pour plate" method on R2A agar). Another objective was to evaluate the lagoon's influence on water quality of Ipanema and Leblon beaches. Physical and chemical data were acquired too. Sub-superficial water samples were taken monthly, from December 1999 to October 2000. On lagoon, the cultivated bacteria abundance varied from 6.9x10(5) to 5.0x10(7) CFU.100 mL-1. On Ipanema and Leblon beaches, this parameter yielded 1.4x10(5) and 2.8x10(6) CFU.100 mL-1, respectively. Total...

From the results obtained in four years of monthly fish sampling and salinity and temperature verification of Lagoa Rodrigo de Freitas lagoon, an analysis of the monthly capture distribution of the nine most representative species, Brevoortia áurea (Spix, 1829), B. pectinata (Jenyns, 1842), Genidens genidens (Valenciennes, 1839), Geophagus brasiliensis (Quoy &amp; Gaimard, 1824), Cerres aprion Cuvier, 1829, Jenynsia lineaía (Jenyns, 1842), Mugil liza (Valenciennes, 1836), Poecilia vivipara (Bloch &amp; Schneider, 1801) and Xenomelani-ris brasiliensis (Quoy &amp; Gaimard, 1824) was performed. The results show that Lagoa waters have an average salinity of 11.06% during the sampling period. Temperature showed its highest values from November to...
