“…It must be emphasized that it was high level desalinization establishment using the two stages aerobic culture. For example, Panwichian et al reported that reduction to 31% of Na removal was observed using photosynthetic bacteriacul- ture from the seawater [9]. The high level of Na removal from seawater found in our study has not been previously reported when using photosynthetic bacteria, including cyan bacteria.…”

The removal of sodium (Na) from seawater using two photosynthetic bacteria was investigated using Rhodobacter sphaeroides SSI (SSI) and Rhodovulum sp. which is a marine photosynthetic bacterium. Both Rhodovulum sp. and acclimated SSI were shown to grow well in a 3% NaCl supplemented glutamate-malate medium. The maximum rate of Na removal was 39.3% by SSI and 64.9% by Rhodovulum sp. after two days cultivation under static light conditions. However, Na was re-released back into the medium after two to three days. When a nutrient-supplemented seawater medium (3.3% NaCl, 13.10 gNa/l) was used, the maximum Na removal rates were 30.3% (9.05 gNa/l) by SSI and 48.9% (6.69 gNa/l) by Rhodovulum sp., under static light conditions. Similar growth and Na removal rates were found under aerobic dark cultivation. In this case, no re-release of Na was observed with either bacterium. Two stages culturing was conducted first, with Rhodovulum sp. and then with SSI replacement. The Na concentration was reduced to 0.79 gNa/l (94.0% removal) after cultivation for eight days under aerobic dark conditions. The supernatant was applied successfully as a liquid fertilizer in the cultivation of Japanese radish.

“…These stains were cultured in a 3% NaCl seawater medium and exhibited Na reduction under microaerobic light (static light) and aerobic dark conditions. However, the precise function of Na reduction wasunclear [9]. Amezago et al reported low-cost bio-desalinization of seawater using photosynthetic bacteria [10].…”

“…Rhodopseudomonas strains are also capable of hydrogen gas production both anaerobically in the dark and photosynthetically using organic compounds as a hydrogen source (Hillmer and Gest, 1977;Mangels et al, 1986;Suwansaard et al, 2009;Panwichian, et al, 2010;Suwansaard et al, 2010) R. palustris can produce hydrogen gas from palm oil milling effluent which has a very high oil and fatty acid content (VFAs-Volatile Fatty Acids) (Suwansaard et al, 2009).…”

“…Rhodopseudomonas DK6 can reduce very high BOD and COD loads but requires fixed nitrogen. Moreover, purple non-sulfur bacteria isolated from shrimp pond sediments in Southern Thailand can remove heavy metals and sodium from contaminated shrimp ponds: two strains were isolated, NW16 and KMS24 (Panwichian et al, 2010).…”

“…Sin embargo, durante los últimos 20 años los productores de camarón han sufrido enormes pérdidas económicas, debido al incremento de enfermedades que afectan su producción y exportación (Zokaei et al 2009, Panwichian et al 2010; además, porque han encontrado su mayor dificultad en el manejo de la calidad del agua, causada por la acumulación de materia orgánica y metabolitos tóxicos para los camarones, como los compuestos nitrogenados (Ladino-Orjuela & Rodríguez-Pulido 2009, Zhou et al 2009.…”

Efecto de microorganismos con potencial probiótico en la calidad del agua y el crecimiento de camarón Litopenaeus vannamei (Decapoda: Penaeidae) en cultivo intensivo Abstract: Microorganisms effect with probiotic potential in water quality and growth of the shrimp Litopenaeus vannamei (Decapoda: Penaeidae) in intensive culture. The use of probiotics has gained acceptance in aquaculture, particularly in maintaining water quality and enhancing growth in organisms. This study analyzed the effect of the commercial (EM TM , Japan) natural product composed by (Rhodopseudomonas palustris, Lactobacillus plantarum, Lactobacillus casei and Saccharomyces cerevisiae) added to the water, in order to determine its effect in water quality, sediment and growth of L. vannamei under intensive culture. The evaluation included three treatments with a weekly addition of EM: i) tanks without probiotics (C), ii) tanks with a dose of 4L/ha (EM1) and iii) tanks with a dose of 10L/ha (EM2). The treatment C was carried out three times, while treatments EM1 and EM2 were carried out four times. A total of 4 350 shrimps were measured for total length and weight, to calculate total and porcentual weight gain, daily weight gain, specific growth rate (TCE), and food conversion factor (FCA); besides, the survival rate was estimated. The use of probiotics allowed a shorter harvest time in treatments EM1 (90d) and EM2 (105d) with relation to the treatment C (120d). Treatments EM1 and EM2 were within the recommended intervals for culture, with respect to treatment C. The use of probiotic bacteria significantly regulated pH (EM1, 8.03±0.33; EM2, 7.77±0.22; C, 9.08±0.35) and reduced nitrate concentration (EM1, 0.64±0.25mg/L; EM2, 0.39±0.26mg/L; C, 0.71mg/L). Water pH mostly explained the variance with respect to the treatments. Treatment EM2 presented the greatest removal of organic matter (1.77±0.45%), whereas the contents of extractable phosphorus increased significantly in treatment EM1 with 21.6±7.99mg/kg and in treatment EM2 with 21.6±8.45mg/kg with control relation (14.3±5.47). The shrimp growth was influenced by dissolved oxygen, salinity and pH in the sediment, establishing that salinity was the most important variable in the weight with a negative association.
