    SOYBEAN FACTORS RELATING TO GAS PRODUCTION BY INTESTINAL BACTERIA (1970)

    Notes: An in vitro assay showed that toasted, dehulled, defatted soybean meal contains a gas-producing factor and a gas-inhibiting factor. The oligosaccharides—sucrose, raffinose and stachyose—are associated with the gas-producing factor when incubated in thioglycollate media with anaerobic bacteria of the intestinal tract of dogs. The phenolic acids in soybeans—syringic and ferulic acid—are effective gas inhibitors in vitro and in intestinal segments of dogs. The lipids, proteins and water-insoluble polysaccharides of soybean meal have no gas activity. During fermentation, gas production parallels the formation of monosaccharides by enzymatic hydrolysis of raffinose and stachyose. The amount and composition of gas produced from cottonseed and peanut meal were comparable to soybean meal.

    Epidemiological study of chronic bronchitis with special reference to effect of air pollution (1971)

    Notes: Summary From 1962 to 1969 an investigation on chronic bronchitis was conducted to clarify the chronic influence of air pollution to human health in 9 areas selected from Osaka and Hyogo prefectures showing different degrees of air pollution. Self-administered questionnaire based upon the standard of the British Medical Research Council's Committee was distributed to every residents over 40 years of age in surveyed areas. The questionnaires numbered 36374 with response rate of 85.9%. Cases of chronic bronchitis were diagnosed from the responded following the Fletcher's criteria of chronic bronchitis. Those cases were asked to take further examinations consisting of doctor's direct interview by the standardized questionnaire by the British Medical Research Council's Committee, chest X-ray test, pulmonary function test by McKenson's Vitalor and other optional medical examinations. At the same time, some apparently normal subjects and some other who had less severe symptoms of sputum, cough and/or short breath were likewise medically checked up as the controls. From this investigation, it became clear that the prevalence of chronic bronchitis is influenced by age, smoking and air pollution (sulfur dioxide). The relation among age, smoking and air pollution with the prevalence of chronic bronchitis is mathematically analysed as follows: Y=1.94α+10−4 · 3 · N(x −20)2−3.18 where Y: prevalence of chronic bronchitis, N: smoking quantity per day, α: sulfur dioxide, x: age.

    Hydrocarbon fermentations using Candida lipolytica. I: Basic growth parameters for batch and continuous culture conditions (1971)

    Notes: Candida lipolytica (strain ATCC 8661) was grown on a simple defined medium with n-dodecane as sole carbon source under batch and continuous fermentation conditions. The composition of cellular material recovered from the fermentations, the oxygen demand of the cells, and the effect of operating conditions on cell growth were evaluated experimentally. These basic data are presented and discussed.

    Hydrocarbon fermentations using Candida lipolytica. II: A model for cell growth kinetics (1971)

    Notes: A mechanistic model is presented for the growth kinetics of a yeast grown by submerged aerobic fermentation using a liquid hydrocarbon as sole carbon source. The model is based on the assumption that cell growth is governed by the extent of probable cell attachment at the hydrocarbon oil-droplet surfaces in a four-phase dispersion. An analytical expression has been developed for the model. It is shown that for the case of relatively small oil droplets, the model predicts the present and previous experimental data for growth of yeasts (Candida species) in n-alkane systems. The model is further examined for maximal growth in terms of substrate dilution rate and agitation power consumption for a continuous fermentation process.
