Micro-Kjeldahl determination of protein content in the cells was not s
uitable for the determination of biomass because of the changing compo
sition of the cells. The significant correlation was found during cult
ivation between the values of the hexosamine assay and those correspon
ding to the dry weight method (r(2) = 0.98, slope = 1.04) which showed
the validity of both hexosamine and dry weight methods, with the form
er being a simple, reliable and not time consuming alternative for the
biomass estimation of Sclerotium rolfsii during scleroglucan producti
on.
