✦ Synopsis

Aspergillus japonicus was grown in the presence of various aromatic compounds at 0.1 and 1 mg/mL, and extracellular xylanase and arabanase activities were measured. Some of the aromatic compounds tested, especially at the higher concentration, suppressed the appearance of hemicellulase activities, expressed as xylanase or arabanase. Vanillin at 1 mg/mL in the presence of either xylan or araban completely suppressed growth, and guaiacol and p-coumaric acid markedly inhibited the growth of A. japonicus. The effects of the aromatic compounds on the activity of crude enzyme preparations were also ascertained. in vitro arabanase activity was affected more than xylanase activity.

Lignocellulose can be readily hydrolyzed into a mixture of sugars using dilute mineral acids. During hydrolysis, a variety of inhibitors are also produced which include aromatic alcohols from lignin and furfuryl alcohol from pentose destruction.

## Background: Lncap cells are androgen-sensitive human prostate cancer cells. they are characterized by a bell-shaped growth curve in response to increasing doses of dihydrotestosterone (dht) in culture. at a low concentration of dht (0.1 nm), these cells show an increase in proliferation, but the
