According to the experimental results, the growth inhibition of M. aeruginosa was evidently observed by applying TiEPS balls, and increased\n proportionally with the surface area coverage of TiEPS balls. Based on the comparison of both specific growth rate (<jats:italic>\u03bc<\/jats:italic>) and first-order degradation rate (<jats:italic>k<\/jats:italic>), the experimental cases using TiEPS balls with surface area coverage of 100% suppressed more significantly the growth\n of <jats:italic>M<\/jats:italic>. aeruginosa cultured from both indoor and outdoor experiments during the initial period of the experiment. However, through the whole experiment, both <jats:italic>\u03bc<\/jats:italic> and <jats:italic>k<\/jats:italic> values between experimental cases using TiEPS balls and EPS balls with surface area coverage of 100% were\n not statistically different (<jats:italic>p<\/jats:italic> &gt; 0.05). These results indicated that the photocatalytic degradation effect was dominant during the initial period of application, and the irradiation shading became dominant with the elapsed time. Therefore, the growth of <jats:italic>M. aeruginosa<\/jats:italic> can be\n suppressed due to both synergistic and combinational effects of photocatalytic degradation and irradiation shading under natural solar light. Based on the aforementioned results, self-floating TiEPS balls produced from this simple and cost-effective mass production technique can be readily\n applied to inhibit the excessive growth of harmful algae in the stagnant water body.<\/jats:p>","DOI":"10.1166\/jnn.2020.17637","type":"journal-article","created":{"date-parts":[[2020,4,17]],"date-time":"2020-04-17T04:36:38Z","timestamp":1587098198000},"page":"5775-5779","source":"Crossref","is-referenced-by-count":3,"title":["Growth Inhibition of <i>Microcystis aeruginosa<\/i> Using TiO<sub>2<\/sub>-Embedded Expanded Polystyrene Balls"],"prefix":"10.1166","volume":"20","author":[{"given":"Jin Chul","family":"Joo","sequence":"first","affiliation":[{"name":"Department of Civil and Environmental Engineering, Hanbat National University, Daejeon, 34158, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ga Young","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering, Hanbat National University, Daejeon, 34158, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Min Ji","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering, Hanbat National University, Daejeon, 34158, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chang Hyuk","family":"Ahn","sequence":"additional","affiliation":[{"name":"Korea Institute of Civil Engineering and Building Technology, 10223, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saeromi","family":"Lee","sequence":"additional","affiliation":[{"name":"Korea Institute of Civil Engineering and Building Technology, 10223, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jae-Roh","family":"Park","sequence":"additional","affiliation":[{"name":"Korea Institute of Civil Engineering and Building Technology, 10223, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jong Kyu","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Kyungnam University, Changwon, 51767, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"17","container-title":["Journal of Nanoscience and Nanotechnology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ingentaconnect.com\/content\/asp\/jnn\/2020\/00000020\/00000009\/art00084","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,4,24]],"date-time":"2020-04-24T04:40:03Z","timestamp":1587703203000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ingentaconnect.com\/content\/10.1166\/jnn.2020.17637"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,9,1]]},"references-count":0,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2020,9,1]]}},"alternative-id":["1533-4880(20200901)20:9L.5775;1-"],"URL":"https:\/\/doi.org\/10.1166\/jnn.2020.17637","relation":{},"ISSN":["1533-4880"],"issn-type":[{"value":"1533-4880","type":"print"}],"subject":[],"published":{"date-parts":[[2020,9,1]]}}}
