this spot test differentiates penicillinase activity from cephalosporinase activity and distinguishes between beta-lactamase and acylase activities , since the end products of acylase [ the common side chain , d ( - ) -alpha-aminophenylacetic acid , and the intact beta-lactam nuclei , 6-aminopenicillanic acid and 7-aminodeacetoxycephalosporanic acid ] are not fluorescent .
