Regulation of membrane - associated laccase synthesis in liquid culture of Coprinus congregatus
|
|
|
|
|
Abstract
|
|
|
|
When Coprinus congregatus was cultivated in low pH YpSs medium(pH 4.2), the culture supernatant turned brown earlier than that of normal(pH 7.1) medium resulted from the melanization synthesized by the secreted lactase reaction. The pH of medium became 5.2 after 24 h incubation. Lactase which was deeply related to the fungal development might also be implicated in the neutralization of excess hydrogen ions to protect from acidification of cytoplasm.
