Bioremediation of bacteria pollution using the marine sponge Hymeniacidon perlevis in the intensive mariculture water system of turbot Scophthalmus maximus

Abstract

Sessile filter-feeding marine sponges (Porifera) have been reported to possess high efficiency in removing bacteria pollution from natural or aquaculture seawater. However, no investigation has been carried out thus far in a true mariculture farm water system. Therefore this study sought to investigate the ability of the marine sponge Hymeniacidon perlevis to bioremediate the bacteria pollution in the intensive aquaculture water system of turbot Scophthalmus maximus. Sponge specimens were hung in fish culture effluent at different temperature to investigate the optimal temperature condition for bacteria removal by H. perlevis. Turbots S. maximus were co-cultured with sponge H. perlevis in 1.5 m(3) of water system at 15-18 degrees C for 6 weeks to control the growth of bacteria. It was found that H. perlevis was able to remove pathogenic bacteria efficiently at 10-20 degrees C, with a maximal removal of 71.4-78.8% of fecal coliform, 73.9-98.7% of pathogenic vibrio, and 75.0-83.7% of total culturable bacteria from fish-culture effluent at 15 degrees C; H. perlevis continuously showed good bioremediation of bacteria pollution in the S. maximus culture water system, achieving removal of 60.0-90.2% of fecal coliform, 37.6-81.6% of pathogenic vibrio, and 45.1-83.9% of total culturable bacteria. The results demonstrate that H. perlevis is an effective bioremediator of bacteria pollution in the turbot S. maximus culture farm water system.

The Effect of Depth on the Morphology, Bacterial Clearance, and Respiration of the Mediterranean Sponge Chondrosia reniformis (Nardo, 1847)

“…Sponges process huge amounts of water daily at up to 900 times their body volume of water per hour and filter 50,000 liters of seawater per liter of sponge volume per day [ 7 , 8 , 9 , 10 ], which is comparable to well-established suspension feeders such as mussels [ 11 , 12 , 13 ]. Sponges have a high efficiency and capacity for particle retention [ 3 , 4 , 14 ], preferably small particles (<10 µm) such as bacteria [ 4 , 15 , 16 , 17 , 18 ], phytoplankton [ 3 , 19 ], viruses [ 20 ], and dissolved organic matter [ 21 , 22 , 23 , 24 ]. This efficient and versatile filtration makes sponges key drivers of the uptake, retention, and transfer of energy and nutrients within benthic ecosystems [ 25 , 26 , 27 , 28 ] and makes them interesting candidate species for the bioremediation of organic pollution, such as waste streams from aquaculture [ 29 , 30 , 31 ].…”

“…Efficient pumping of the surrounding seawater through the sponge body is of vital importance to sponges with regard to processes such as respiration and reproduction and feeding (Bergquist 1978; Simpson 1984). Sponges have a high efficiency and capacity for particle retention (Reiswig 1971, 1975, Ribes et al 1999), preferably small particles (<10-µm), such as bacteria (Reiswig 1975b; Milanese et al 2003; Fu et al 2006; Zhang et al 2010), phytoplankton (Reiswig 1971; Pile et al 1996;) and even viruses (Hadas 2006). More recent, it has become evident that sponges can also utilize dissolved organic matter as major component of their daily diet (Yahel et al 2003; De Goeij et al 2008, Mueller et al 2014).…”

Bioremediation strategies are being developed for and deployed in the aquaculture industry, primarily as a means to capture nutrient leachates and suspended solids from effluent and sediments (Chávez-Crooker & Obreque-Contreras 2010, Kim et al 2013, but also to reduce pathogen discharge to the environment (Zhang et al 2010).…”
