The organic acid fermention of Pen. chrysogenunz Q 176 and of the Pigmentless sultant were studied, in surface and shaking culture on medium containing 10% glucose. Q 176 and the Pigmentless sultant produced 51.7% and 47.1% gluconic acid, 10.2% and 9.8% succinic acid, and 0.4% and 0.32;% lactic acid respectively, based on the consumd sugar, utilization of sugar being both 98%. Other organic acids usually produced by molds were not found by these molds. In organic acid productivity, Q 176 and Pigmentless sultant strain were considered to be almost the same, but Pigmentless sultant proved to be somewhat weaker in the productivity. So this sultant may be called regressive mutant in these particular properties too, as similar in the case of other mutants.
