Resultantly, we have not made quiet great progress in theory, exploiting local bacterium and developing MEOR simulation software, though we bore fruit in laboratorial studies and field tests in the past. Therefore, the urgent affairs are setting up database of local bacterial category and carry through the numerical simulation of MEOR.

所以，尽管我国在微生物驱油的室内研究和矿场实验上取得了可喜的成果，但在理论研究和本地菌种开发等方面仍然有所不足，且至今没有属于自己的微生物采油模拟软件。

By setting the retting duration of 20 hours, the factors affecting the residual gum percentage of the retted kenaf fibers are studied. The experimental results show clearly that the following factors have the significant influence on the residual gum percentage of the retted kenaf fibers and show the obvious variation tendency. The preferred processing parameters are as follows: pH value 7. 0、bath ratio 1: 50、reuse percentage of retting liquid 50%、air flow volume 2. 5L/min、temperature 40℃、nitric additives (ammonia is better than nitrates) percentage 0.45%.By comparison with anaerobic retting, the retting duration using aerobes is much shorter than that using anaerobes.
