In experiments seeking for suitable industrial media for the submerged culture of Eremothecium ashbyii, glucose, sucrose, cane molasses, malt extracts, peptone, meat extracts, corn steep liquor, cereal germs and their extracts, beans and sardine meals were tested. A medium containing 3% (as sugar) of molasses and 5% of dried sardine meals was found to be most suitable.

The significance of the initial pH of medium and a few conditions of the inoculum was studied. (1) The optimum of initial pH was 6.4-6.8,but no considerable change in riboflavin production was found between pH 6-7. (2) One per cent of inoculum was sufficient for over 3-4 days culture. (3) No change in riboflavin production was induced by changes in the media, for the inoculum. (4) When the inoculum cultured for 36 hours was used after 7 or 14 days, the riboflavin production was decreased and the mycelial growth was increased. (5) The riboflavin production was not influenced by successive inoculation with fresh seed. (6) Inoculating one after another using a part of the submerged culture caused no change in the riboflavin production.

(1) Nutrients of carbon and nitrogen sources were added stepwise to the medium and changes in the riboflavin production were investigated. (2) Sugar was a little more effective when given in an increasing amount than the amount was constant. The effect fell when given decreasingly.

The effects of thiamine and cocarboxylase on the human subject were compratively studied, the following responses being taken as indices : Sawada's urinary reaction, Miyaji's hepatic-function test, the rate of increase in the thiamine content of blood, the amount of thiamine excreted in urine, the percentage of thiamine detectable in red blood cells after its administration, the detoxicating power on santonin, and the production of esterified thiamine due to insulin injection. The results were as follows : No difference was found between the two with regard to level of thiamine in blood, urine and red blood cells. Cocarboxylase was more effective than thiamine in the power of detoxicating santonin and in the results of the urinary reaction and hepatic-function test. The amount of esterized thiamine was found to increase slightly by administration of insulin.

Using our fluoromicroscopic method, variations of riboflavin of retina in relation to the morphological changes of it were observed histochemically. It is noticed that riboflavin distribution varies in close connection with the movement of pigment granule in pigment epithel cells. It is consdered that riboflavin of rods, being supplied from pigment granule at light adaptation, is concerned in the formation of rhodopsin with co-existing vitamin A in them at dark adaptation.

Investigation on the seasonal variation of vitamin B_<12> content in activated sludge was made three times a month for a year with the samples in the sewage treatment plant of Kyoto. The results that periodic variation is recognized in the vitamin content. That is to say, the highest vitamin content of over 10 μg/g on dry basis is observed in the samples of September to November, the lowest of 5-6 μg/g in June, and small peaks also in May and February. The results obtained with the samples of Kyoto are nearly in agreement with those in the sewage treatment plants of Nagoya, previously reported. (Vitamins 8,443,1955)

IS VITAMIN B_<12> FORMED IN ACTIVATED SLUDGE PROCESS DURING AERATION ?

Several experiments were carried out in order to know whether or not vitamin B_<12> would be formed during aeration in the municipal activated sludge plant. Since much larger amount of vitamin B_<12> is contained in the sludge added as seed at the entrance of the aerator as compared with the vitamin presumably formed during aeration, it might be impossible to determine the amount of vitamin increased during the treatment. On the other hand, calculating from the amount and vitamin B_<12> content of activate sludge discharged and those of sewage entering into the plant, the presumably formed vitamin B_<12> is supposed to be the order of one tenth mμg per ml of sewage and the vitamin added as return sludge is in the order of one tenth μg. On the basis of this reduction, it is supposed to be impossible to determine by the microbioassay method the amount of the vitamin formed during aeration process experimentally.
