<p>Chromogenic substrate targeting cellulases</p>

<p>Aldol® 515 nonanoate hydrochloride is a chromogenic and fluorogenic enzyme substrate for detection of lipase activity. The colorless product is cleaved by C9 esterases produced by bacteria in liquid or solid media, yielding a red color and red fluorescence when Aldol® 355 fluorescence enhancer or a suitable matrix is present. Aldol® 515 nonanoate can be used under aerobic and anaerobic conditions. Well detectable color/fluorescence of bacterial colonies or liquid cultures is obtained within 24-48 h. In the presence of a purified lipase, color and fluorescence develops within minutes to few hours.</p>
