JF - Journal of Vocational Education in Agriculture JA - JVEA VL - 5 IS - 2 SE - Research Article DO - UR - https://li01.tci-thaijo.org/index.php/JVIA/article/view/252488 SP - 1-7 AB - <p>The aim of this study was to examine the efficiency of modified media compared to the standard Guillard’s F/2 media and TMRL (Total Mixed Ration Liquid media) on growth of <em>Thalassiosira </em>sp. The diatom was cultured in 10 liter glass containers filled with 5 liters of solution medium. The growth of the diatom was examined using cell counting method every 24 hours. Results revealed that the maximum growth of <em>Thalassiosira </em>sp. after 96 hours was found in the modified culture media (0.19±0.11×10<sup>6</sup> cells/ml) followed by F/2 (0.17±0.06×10<sup>6</sup> cells/ml) and TMRL (0.16±0.06×10<sup>6</sup> cells/ml), respectively. However, there were no significant differences among the three treatments. The results indicated that, apart from F/2 and TMRL, the modified culture media could be another suitable choice to be recommended for <em>Thalassiosira </em>sp. production.&nbsp;</p> ER -
