We conducted this research in order to investigate the potential of a new material called glass pumice for use as a microorganism immobilization carrier to improve aquaculture pond water quality. The pH adjustment capacity and the Rhodopseudomonas palustris P1 cell adsorption capacity of glass pumice were measured. The immobilized Rps. palustris P1 and the free sample were compared to determine which had an enhanced NH4+‐N and NO2−‐N removal efficiency. The results showed that glass pumice significantly affected the pH of the acid solution (P < 0.05); the pH increased from 3.0 ± 0.08 to 7.21 ± 0.13 in 12 H. Rps. palustris P1 adsorption to glass pumice was rapid and reached equilibrium within 60 Min. The Langmuir adsorption parameter data showed that glass pumice had a higher affinity for Rps. palustris P1 than SiO2 powder, with an adsorption capacity of 4.02 × 108 cells g−1. The maximum NH4+‐N and NO2−‐N removal rates by immobilized Rps. palustris P1 were 134.82 ± 0.67% and 93.68 ± 0.14% higher than those of nonimmobilized P1, respectively. Based on the above results, we propose that glass pumice is potential as a microorganism carrier material in aquaculture water treatment.

将Phodopseudomonas palustris P1固定在玻璃浮石上，以提高水产养殖池塘水中NH4 + -N和NO2- -N的去除率。
我们进行了这项研究，以研究一种称为玻璃浮石的新型材料作为微生物固定载体改善水产养殖池塘水质的潜力。测量了浮石的pH调节能力和Phodopseudomonas palustris P1细胞的吸附能力。固定的Rps。比较palustris P1和游离样品，以确定哪些具有更高的NH 4 + -N和NO 2 -- N去除效率。结果表明，玻璃浮石对酸溶液的pH有显着影响（P <0.05）。在12 H.Rps中，pH从3.0±0.08增加到7.21±0.13 。ustP1对玻璃浮石的吸附迅速，并在60分钟内达到平衡。Langmuir吸附参数数据表明，玻璃浮石对Rps的亲和力更高。pal粉P1比SiO 2粉末，吸附容量为4.02×10 8个 细胞g -1。固定Rps的最大NH 4 + -N和NO 2 -- N去除率。palustris P1分别比未固定的P1高134.82±0.67％和93.68±0.14％。基于以上结果，我们认为玻璃浮石作为水产养殖水处理中的微生物载体材料具有潜力。
