ジャーナル フリーEffects of hydrogen-ion concentration upon the physiology of bacteria have been studied along two main paths, namely, on the growth rate of bacteria, and on the other physiological activities of them. The first has attracted much more attention of the bacteriologists than the second, but much is left to be desired in the technique. The second mostly concerns with the influence of initial pH of the medium on the fermentation by lactic acid bacteria, Bact. coli, etc. Such investigations as carried out by MEYERHOF(1) into the oxidation of ammonia and nitrite, or by ITANO (2) into the decomposition of broth media in relation to the afore-mentioned con-ditions are not many. Still fewer are the papers which have dealt with the decomposition of the fish muscle under such conditions.
The present papcr embodies my observations on the effects of pH on the rate of the decomposition as well as the rate of growth of bacteria in the fish muscle suspensions.抄録全体を表示PDF形式でダウンロード (137K) -

ジャーナル フリーBased on the tank experiments, polar diagrams were drawn for model plates of various shapes. As the configuration of the trawl rope is also known from calculations, the most effective angle of attack to keep a plate as deep as possible below the wa'er surface is deter-mined, when the length of a rope of a certain kind and a towing speed are given.抄録全体を表示PDF形式でダウンロード (145K) -

ジャーナル フリーWith the cotton cords having the same linear density but, consisting of the yarns of different sizes, it was found that the finer the yarns, the stronger the cord against repeated blows. The influence is, however, not so clear as in the case of breaking strength, and is more clearly seen with finer cords than the thicker.抄録全体を表示PDF形式でダウンロード (112K) -

ジャーナル フリー20, 600 individuals of Theragra chaigogramma (Pallas) were•angled in the waters 8 miles NW of Iwanai Harbour, Hokkaidô and 10 miles off Teradomari Harbour, Niigata Pref. from Dec. 1935 to Mar. 1936. With regard to 525 samples out of them, the body lengths and weights were measured, the age was determined counting the winter rings on vertebra, and the sex and mat rity were also determined (Table 1, 2 and Fig. 1). Following results are obtained.
(1) Sex ratio is nearly the same for both of the fishing grounds, namely male 40% and female 60% (2) In the opening fishing season, the shoals are mainly consisted from immature fishes, while, in the closing season the percentage of spent fishes markedly increases. (3) Shoals are composed of the 6 age groups of 3 to 8 years old. (4) On the both fishing grounds investigated, is the growth rate nearly the same.抄録全体を表示PDF形式でダウンロード (112K) -

ジャーナル フリーThe writer examined the epipode, which is a dorso-lateral outgrowth of the foot, of four important forms of Japanese abalones, viz., Haliotis gigantea Gmelin, H. gigantea sieboldi Reeve, H. gigantea discus Reeve and H. kamtschtkana Jonas. Figures A, B & C show that the first three cau be easily distinguished by this character. But the fourth can not be separated from the third since both are similar in the character under consideration.抄録全体を表示PDF形式でダウンロード (181K) -

ジャーナル フリー1) A cultural experiment was carried out in order to determine the morphology and embryology of either zoospores and gametes of Hormiscia penicilliformis (ROTH) FRIES and H. incrassata (KJELLM.) COLLINS.
2) In H. incrassata all kinds of the reproductive cells, namely the anisogametes, macro-and microzoospores are produced in one and the same filament. The macrozoospores are obovoid in shape, 30μ long, l6μ wide, provided with 4 cilia at the anterior end which is square pyramidal in shape, and extending posteriorly into a long tail. The tail is up to 30μ in length. The microzoospores are smaller, ovoid in shape, l6μ long, 10μ wide, with 4 cilia at the anterior end which is not pyramidal, and with a shorter tail.
3) The zoospores appear to be negatively phototactic. On germination they give rise directly to new filaments. Within three weeks the young filaments become composed of ten or more cells and already provided with the characteristic extramaterical rhizoids arising from some of the basal segments.
4) Sexual reproduction by 2-ciliated anisogametes. The macrogametes are spindle-shaped, 14μ long, 6μ wide, and bright green in color, while the microgametes much smaller, ovoid in shape, 4μ long, 2.5μ wide, and pale green.
5) The chromatophore of H. incrassata is coarsely reticulate with many large openings, containing a number of refractive globules, which the writer believes to be nuclei and not pyrenoids as interpreted by previous investigators. The chromatophore changes its form according to the reproductive condition of the segment. The breaking up of the chromato-phore into areolae precede the formation of the reproductive cells as has been described by some authors. In young sporangial segments the nuclei undergo mitotic division repeatedly.抄録全体を表示PDF形式でダウンロード (480K) -

ジャーナル フリーGelidiun, one of the important marine products of Japan, has been studied by many authors concerning its propagation. But, on the matter of the life-history of this alga, the investigation has not yet been fully done. Therefore I set about to clear out some points of this problem, especially, the germination and development of this seaweed at the first step udder a special adjustment planned by Mr. S. MIYAGI. The results of my observations may be summarized as follows:-
Season of the spore-formation : The sporophytes mature earlier than the gametophytes; tetraspores liberate from the mother plants from June to August and carpospores from August to October as a rule, but some of the plants ripe in May and some in November.
Development of the new plants : The new plants germinate in summer and at first they develope to small creeping fronds with many small buds growing out here and there. And these buds begin to grow up to erect fronds which form the reproductive organs afterwards in them.
Vicissitude of the plants : The plants mostly grow from winter to early summer and after then they densely branch and form the reproductive organs.
After libration of the spores, the mother fronds still live and grow continuously for a few years, and repeatedly form spores every year.抄録全体を表示PDF形式でダウンロード (436K) -

ジャーナル フリーThe relation between typhoid germ and shellfishes, especially oysters, has been intensively studied by many authors, and definite rules and regulations have been put in force for keeping the oysters free from the contamination by human excrement. But the bloody-clam has not yet been dealt with from the view-points of sanitary science.
The material was obtained from several districts of northern as well as southern Japan (Aomori, Miyagi, Tiba, Tôkyô, Aiti, Kumamoto Prefectures, Hokkaidô and Korea.) during a period from January to February, 1936. Bacteriological analysis done according to Dr. TOHYA-MA'S improved method show that the B. coil score of shell oysters under 50 amounts to 96% of the total, including 60% of the score 0 and also 88% of the score under 5. The remaining 4% of the total belong to the score over 50 by American standard. (see Table 1)抄録全体を表示PDF形式でダウンロード (142K) -

ジャーナル フリーThe transmission of light in water has been observed at Lake Osoresan and off Asamusi, Mutu Bay, by means of KI-methods after PEARSALL and after MCCREA. The transmission of these waters is not so uniform as usually expected, and it markedly decreases with the depth.
The compensation point and the lower limit of assimilation in Ulva pertusa KJELLMAN were also determined.抄録全体を表示PDF形式でダウンロード (218K) -

ジャーナル フリーWith a view to a acertaining whether or not such marine animals as fish and whale have this substance, the writers made experiments with the livers of the bonito and the whale. The basal ration used in the experiment were composed of casein 25g, salt (MCCOLLUM and SIM-MOND'S salt mixture No. 115+ few amounts of NaF and KJ), starch 40g, lard 15g, cane sugar 17g, codliver oil 9g, dried yeast 8g.
The results obtained are shown Figs. 1-3. The substance under consideration were found to exist in the insoluble as well as soluble parts of the bonito-liver and also in the extract of the whale-liver obtained by digesting it with papain.抄録全体を表示PDF形式でダウンロード (205K) -

ジャーナル フリーThe present paper deals with the determination of the Ascorbic acid in various organs of marine animals (Table 1 and 2) and in the marine products (Table 3), using TILLMAN'S 2•6-di-chlorphenol-indophenol titration. The materials were grounded with trichloracetic acid, extract-ed with 5% trichloracetic acid solution, and were filterd (method of BIRTH, HARRIS and RAY). 0•05 c.c. of the pigment solution was titrated with the filtrate. The Tillman's solution was al-ways titrated with the crystallised ascorbic acid. The mean value of the two titrations were summarised in Table 1-3. The ascorbic acid is present in various organs of the fish, the crus-tacea and the mollusca. Of these organs, the spleen, the lens and the kidney are richest in the ascorbic acid and muscle is poorest in it. “Asakusanori”, the commercial preparation of the seaweed Porphyra tenera, is rich in it, ca 800mg%.抄録全体を表示PDF形式でダウンロード (251K) -

ジャーナル フリーThe muscle of the sardine was grounded, boiled fer 5 minutes at 98°C was wrapped with a cloth and was pressed in the perforated iron-cylinder (inside diameter 8•8cm., height 10•0cm pore-diameter 0•6cm) with a hydraulic press.
As shown in Figs. 1 and 2, the amount of expressed oil reaches an asymptotic condition at a pressure of 50kg/cm2. It is to be seen in Table 1 that the oil content in the pressed residue is constant irrespective of the pressure applied in case the body length of the specimens is equal. At the pressure of 50 kg/cm2 the percentages of oil in the pressed cake and of nitrogen in expressed juice remains almost unchanged when the temperature in heating the material is above 90°C (Fig. 3).抄録全体を表示PDF形式でダウンロード (192K) -
