The alcohol waste from starchy materials have high viscosity due to suspending solid, and the process of separating solid out of the waste is difficult.For such waste, we attempted the reforming of waste by cultivating microbes for the purpose of filtration and utilizaiton of products formed by microbes in flasks.Firstly, the influence of enzymes produced by microbes int he waste was examined (Table 3), and then a screening test was conducted to study the filtration by microbes (Tables 4 and 5). As the result, Asp. oryzae was selected, and filtration was remarkably improved by the cultivation of this strain in wastes and a large amountof liquefying amylase was obtained in the filtrate.Secondly, the utilizaiton of filtrate was attempted. As the result, ・it was found that filtrate could be used as a liquefying agent in case starchy materials were coocked for alcohol fermentation for the purpose of obtaining thick mash without inhibition of fermentation due to the repeated use of the filtrate (Tabel 6 and 7).
