In this study,the fermentation process was designed according to the yield of red pigments produced by Penicillium novae-zeelandiae HSD07B.The components of red pigment were also analyzed.The results showed that the optimal parameters are: PD medium,500 mL flask containing 300 mL medium,the inoculum volume 1 mL (Spore concentration 2× 107 mL-1),initial pH 6.0,rotary speed of 150 r min-1,temperature 30 ℃,oscillating time 40 h.Under the optimal conditions,the maximum concentration of red pigment is 2.2834 4 g L-1.All components of red pigments were analyzed by high performance liquid chromatography (HPLC) and thin-layer chromatography (TLC),and the retention time of four major components were 16.667 min,18.120 min,19.895 min,21.022 min,respectively.

海南东寨港红树林自然保护区位于海南岛东北部,是我国红树种类较多、面积最大的典型分布区.红树林长期遭受海水周期性浸淹,其生态环境与聚磷菌的聚磷过程好氧-厌氧交替环境高度一致,为聚磷菌天然驯化环境.本研究利用BCIP蓝白斑筛选法分离到一株高效聚磷菌A.tandoii SC36,为了进一步分析其聚磷机制,我们采用Illumina Hiseq 2000测序技术完成该菌株的基因组扫描测序.我们共获得了56个
哈维氏弧菌主要分布于海洋环境和海洋生物体中,是多种海洋鱼类和无脊椎动物的条件致病菌,目前关于哈维氏弧菌抗喹诺酮药物的机制研究较为缺乏.通过RNA-seq技术对临床分离的哈维氏弧菌敏感菌株(VS)和耐药株(VR)进行比较转录组测序,经从头拼接(De nove)再组装共得到2,082条Unigene.通过比对,两个样品共鉴定出129个差异表达基因,耐药菌与敏感菌相比有65个基因上调,64个下调.对这些
