The chemiluminescent emission from the luminoI-HaOa-horseradish peroxidase system was enhanced between 2 and 80 times, during the first 5 min, by chemical indicators, such as phenolphthalein, cresolphthalein, phenol red, cresol red, benzidine and o-tolidine. Phenol derivatives showed emission maxima

The chemiluminescence of the luminol-H 2 O 2 -horseradish peroxidase system is increased by fluorescein. Fluorescein produces an enhancement of the luminol chemiluminescence similar to that of phenolphthalein, by an energy transfer process from luminol to fluorescein. The maximum intesity and the to
## Abstract The enzymatic nitration of phenol and __m__‐cresol catalyzed by horseradish peroxidase was studied in the presence of H~2~O~2~ and NaNO~2~. The results showed that the nitration products of phenol were 2‐nitro and 4‐nitrophenols. There was also a small amount of by‐products of hydroquin
