The synthesis of poly ( - hydroxybutyrate - co - - hydroxyvalerate ) by the strain g - iiiy from different precusor was studied. it was found that the strain g - iiiy could accumulate phbv with sucrose as carbon source and propionic acid or valeric acid as precursor. in 2l self - controlled fermentor, the dry cell weight, phbv concentration and phbv content reached 35. 8g ? l - 1, 22. 6g ? l - 1 and 38. 4 % respectively in the case of fermentation for 42 hours and the propionic acid as precursor
研究了添加不同前體物， g - y菌株生產聚-羥基丁酸和聚-羥基戊酸共聚物（ phbv ）的發酵條件，結果表明，此菌株能以丙酸或戊酸為前體，在蔗糖為碳源的條件下合成phbv共聚物；在2l發酵罐中，以丙酸為前體，發酵16小時開始流加丙酸，根據發酵液ph值變化控制丙酸流加量，發酵42小時，細胞干重、 phbv產量和含量分別達到35 . 8g / l ， 22 . 6g / l ， 63 . 13 。 -
The thesis mainly improves unidentification and self - adaptive controlling arithmetic brought forward by marsik and strejc, according to characteristics of inertia and time lag in beer ' s fermentation process. it does n ' t add demands to process model and also makes the unidentification and self - adaptive controlling arithmetic adapt process controlling of complex industry with characteristics of time lag and difficulty to modeling
本論文根據發酵過程具有大慣性、時滯等特點，對marsik和strejc提出的無辨識自適應控制演算法進行了改進，在不增加對過程模型要求的同時，使無辨識自適應控制演算法同樣適用於大滯后、建模困難的復雜工業過程式控制制。
