Identification and Expression of Genes Involved in the Biosynthesis of Penicillin and Its Detection by HPLC in Penicillium chrysogenum
In this study, after identification of genes involved in biosynthesis of penicillin, we evaluated the expression of pcbAB and pcbC genes in P. Chrysogenum. A quantitative PCR (qPCR) approach was used to determine how these genes were expressed in different time courses. In addition, the produced penicillin content was measured using HPLC. qPCR analysis of mRNAs extracted from P. chrysogenum i...

In this study, granulated sludge synthesized in a sequence batch reactor (SBR) and then granulated sludge was transferred to continuous feeding and intermittent discharge (CFID) bioreactor. Two independent variables (air flow rate and hydraulic retention time (HRT)) were considered to optimize the process. Subsequently, long term performance (150 days) of the bioreactor was assessed by monitori...
