    PCR-Based Ribosomal DNA Detection Technique for Microalga (Heterosigma carterae) Causing Red Tide and Its Application to a Biosensor Using Labeled Probe

    A technique for detecting Raphidophycean, a bloom-forming genus of algae, was developed using a specific DNA probe. The design of the probe was based on a sequence polymorphism within the small subunit (SSU) ribo...

    Enhanced eicosapentaenoic acid production by Navicula saprophila

    Changes in the eicosapentaenoic acid (EPA) content of Navicula saprophila grown photoautotrophically and mixotrophically with the addition of acetate were examined in terms of their growth progress. Among four...
