“…Within 168 hours, a lower amount of nitrite was observed in T2 when compared to the control, which can be related to the absence of nitrifying bacteria (Nitrosomonas and Nitrobacter) (Chen et al 2006) caused by the action of antibiotics. This result contradicts the findings of Silva et al (2012), who found that nitrite was significantly higher in the treatment with antibiotic, but did not affect the development of Penaeus (=Farfantepenaeus) brasiliensis Latreille 1817.…”

There is a problem with keeping culture medium completely or partially free from bacteria. The use of prokaryotic metabolic inhibitors, such as antibiotics, is suggested as an alternative solution, although such substances should not harm non-target organisms. Thus, the aim of this study was to assess the effectiveness of antibiotic treatments in inhibiting free-living and biofilm bacteria and their half-life in artificial marine environment using the copepod Acartia tonsa as bioindicador of non-harmful antibiotic combinations. Regarding to results, the application of 0.025 g L -1 penicillin G potassium + 0.08 g L -1streptomycin sulphate + 0.04 g L -1 neomycin sulphate showed great potential for use in marine cultures and scientific experiments without lethal effects to non-target organisms. The effect of this combination starts within the first six hours of exposure and reduces up to 93 % the bacterial density, but the half-life is short, requiring replacement. No adverse changes in water quality were observed within 168 hours of exposure. As a conclusion, we can infer that this treatment was an effective procedure for zooplankton cultures and scientific experiments with the aim of measuring the role of free-living and biofilm in the marine community.

“…ix) It is necessary to evaluate the water quality (ammonia, nitrite, nitrate, phosphate, sulfate) and estimate possible changes in the use of antimicrobials in culture medium caused by the withdrawal of bacteria. The bacterioplankton is responsible for nutrient cycling, and its removal could result in the accumulation of nutrients to toxic levels (Alongi, 1994;Silva et al, 2012). x) Make sure to process and appropriately dispose of the culture and the production medium with antimicrobials avoiding environmental contamination and/or bacteria resistance.…”

A review on the effects of antimicrobials use in cultures of planktonic organisms: a rocedure for ecological experiments

Many questions about the role of planktonic organisms remain unanswered because of the difficulty in obtaining a medium where bacteria and fungi are not present. Moreover, an excess load of these microorganisms in phytoplankton cultures and zooplankton organisms may cause nutrient competition or diseases and consequently the death of the organisms of interest. For this reason, we reviewed several methods that have been used to obtain axenic planktonic cultures through specific metabolic inhibitors, such as antibiotics and antifungal agents. From 1940 to 2016, most research was related to microalgae and crustacean's cultures, with the antimicrobials: penicillin, streptomycin, chloramphenicol, oxytetracycline, neomycin and nystatin being the most frequently used. The studies that applied antimicrobials agents to planktonic cultures were mainly focused on being able to culture them and to answer questions about the role of bacteria in aquatic communities without previous testing their effectiveness or their effects on non-target organisms. Therefore, this review sought to determine the correct use of antimicrobials in cultures of planktonic organisms to prevent bacterial and fungal growth, without causing damage to non-target organisms and may assist in the implementation of ecologically-oriented scientific experiments where bacterial and/or fungal inhibition is necessary.

“…However, other organisms, such as fungi and yeasts, have also been used for probiotic purposes (Devajara et al, 2002;Ribeiro et al, 2008). Research on probiotics for aquatic animals is increasing with the demand for sustainable, environmentally friendly aquaculture (Wang et al, 2005;Farzanfar, 2006;Ravi et al, 2007;Decamp et al, 2008;Li et al, 2008;Gomez et al, 2009;Guo et al, 2009;Liu et al, 2009;Ninawe & Selvin, 2009;Peraza-Gómes et al, 2009;Pai et al, 2010;Shen et al, 2010;Silva et al, 2011Silva et al, , 2012Souza et al, 2011;Zhang et al, 2011).…”

ABSTRACT. The aim of this study was to evaluate the effect of a commercial probiotic on the bacterial and phytoplankton concentration in intensive shrimp farming (Litopenaeus vannamei) with a recirculation system, for one culture period in Rio Grande do Norte, Brazil. Ponds, with mean area of 2.6 ha, were stocked with a density of 98 shrimp m -2 . A commercial probiotic was prepared following the manufacture's specifications and sprayed on the surface of the ponds seven days prior to stocking and then on a weekly basis until harvest. The same procedures were used with all treatments (control and probiotic), with regard to feeding, liming, fertilization, use of molasses and monitoring of water quality. Field data were analyzed using ANOVA, the Tukey test and Chi-square tests. No significant differences between treatments were found for water quality data, but treatment means showed significant differences for total heterotrophic bacteria in the sediment (5.181 ± 0.34x10 4 cfu g -1 and 5.749 ± 0.67x10 4 cfu g -1 ), total heterotrophic bacteria in surface water (4.514 ± 0.95x 10 4 cfu m L -1 and 4.136 ± 0.81x10 4 cfu m L -1 ) and positive sucrose in surface water (2.438 ± 0.72x10 4 cfu m L -1 and 2.203 ± 0.76x10 4 cfu m L -1 ), respectively, for the control and probiotic treatment. Significant differences were also observed throughout the weeks for total heterotrophic bacteria in the sediment, positive and negative sucrose in the sediment, total heterotrophic bacteria in surface and bottom water, and Pyrrophyta percentage values between 10 and 16 weeks. These results showed that the probiotic causes changes in the total heterotrophic bacteria in the sediment and percentage values of Pyrrophyta concentration, improving the environmental quality of the sediment and water in ponds with closed recirculation systems.

El objetivo de esta investigación fue evaluar el efecto de un probiótico comercial sobre la concentración de bacterias y fitoplancton en el cultivo intensivo de camarón (Litopenaeus vannamei) con sistemas de recirculación, para un ciclo de cultivo en Rio Grande do Norte, Brasil. La siembra de camarones se hizo con una densidad de 98 camarones m -2 en viveros de 2,6 ha. Se preparó un probiótico comercial siguiendo las especificaciones del fabricante y rociado sobre la superficie de los estanques siete días antes de la siembra, y después se aplicó semanalmente hasta la cosecha. Los mismos procedimientos con respecto a la alimentación, encalado, fertilización, uso de la melaza y monitoreo de la calidad del agua se utilizaron en todos los tratamientos (control y probiótico). Los datos fueron analizados utilizando el análisis de varianza, prueba de Tukey y Chi-cuadrado. Para los datos de calidad de agua no hubo diferencias significativas entre los trat...
