Improvement in Hydrogen Productivity by a Leavening Bacterium, Enterobacter cloacae GAO, and Its Application to Mantou

Abstract: Enterobacter cloacae GAO, a bacterium isolated from water in which apples have been steeped, is also found in traditional fermented wheat foods. One important characteristic of this bacterium is that it produces hydrogen gas during inflation as these foods are being prepared. The effects of various nutrient sources and culture conditions on the production of hydrogen gas by the bacterium were examined for the improvement of these traditional foods. Glucose was found to be an effective carbon source and casamino acids were found to be effective nitrogen sources. E. cloacae GAO was used to make mantou. When wheat flour with casamino acids was used to make mantou, a better internal structure and taste were obtained.

Slipperiness and Coefficient of friction on the Carpets

Abstract: The slipperiness of the floor covering is the important subject concerned with the safety and the walking comfort. We have examined walking properties on the carpets with a force plate and a lower limb muscles electro-myography. In this paper, the slipperiness of carpets has been examined by measuring a coefficient of friction.Results are shown as follows: 1. The slipperiness is greatly influenced by the outsole materials of shoes. The slipperiness is dependent on a contact area and hardness of the outsole of shoes. The harder an outsole material, the more slippery on the carpets. 2. Wetted carpets are more difficult to slip than dried carpets. This is because a coefficient of friction might become highly due to an increased contact area caused by falling of wetted soft pile fibers. 3. The slipperiness of carpets is more influenced by a pile form than by a pile material. This is because the coefficient of friction is related to a compressibity of carpets and a contact area when compressed by the outsole of shoes. 4. There is a difference in slipperiness among directions of a carpet. The coefficient of friction become higher when shoes slip in the machine tufted direction than when shoes slip in width direction.
