Streptococcus thermophilus grows as chains of variable length which can be broken by processes such as freezing or freeze-drying. This makes survival rates difficult to establish by the agar plate method. Our studies showed that in the presence of cations (Mg
2+, Li
+, and Na
+), these bacteria grew as shorter chains and their enumeration was more precise. A maximal length chain reduction was obtained with sodium concentrations over 80 HIM. Moreover, growth was strongly stimulated by the buffering effect of sodium salts such as acetate and hydrogen carbonate. Finally, this shortening effect of sodium occurred in 17 out of the 20
Streptococcus thermophilus strains tested.

Both microperoxidase and cytochrome
c could be immobilized on a gel for HPLC without losing their activity, the specificity of each immobilized catalyst being similar to that of the free catalyst. With up to 40% of methanol, the chemiluminescence increased as the alcohol concentration increased, while the count decreased with more than 10% methanol for the free cytochrome
c. When used as the reactant for flow injection analysis, they do not need to occupy the cell for the emission of chemiluminescence. The immobilized reactant can measure from 400 pmol to 10 nmol of
tert-butylhydroperoxide (
t-BuOOH) without staining the emission cell.

The anti-urokinase-IgG-resistant plasminogen activator secreted by human embryonic lung diploid fibroblasts, IMR-90 cells (ATCC, C.CL186) was purified to homogeneity from serum-free conditioned medium by a four-step procedure. The fibroblast plasminogen activator was identified as tissue plasminogen activator (t-PA) by the N-terminal sequence of the purified material and the complete amino acid sequence deduced from its complementary DNA (cDNA). The apparent molecular weight was in the range of 64, 000 to 68, 000 by SDS-PAGE and was in the range of 69, 000 to 72, 000 by gel filtration. The fibroblast t-PA showed a stricter substrate specificity than urokinase in enzymatic hydrolysis of various chromogenic substrates. Compared to urokinase, the fibrobrast t-PA was more stable by heating at 95°C for five min and was stable from pH 5 to 10. The fibrobrast t-PA had a higher affinity for fibrin than urokinase.

A cDNA library corresponding to mite protein was screened using anti-
Der f II, a major allergen from the house dust mite
Dermatophagoides farinae, antibody. Three possible clones were obtained that contained cDNA fragments coding for
Der f II, and the nucleotide sequences of the fragments were determined. There were minor differences observed affecting the deduced amino acid sequence among the three cDNA fragments. The amino acid sequence of the purified native
Der f II protein could be analyzed to 45 residues from the N-terminus. As a result of comparison, all the three cDNA fragments code for a mature protein with a derived molecular weight of about 14, 000. The amino acid sequence was not homologous to any known protein sequences and it contained six cysteine residues and no
N-glycosylation sites.

Occurrence of scale and slime in closed systems for industrial water frequently causes trouble. To avoid such trouble, we are trying to develop sensitive sensor systems constructed with piezoelectric quartz crystals for the earliest detection of scale and slime. The proportional relationship between weight gain on the electrode's surface of the crystal and decrease of the oscillation frequency is well-known. However, it is very difficult to stabilize the oscillation frequency in such an environment as salt-containing water. In this study, we can keep the frequency stable by controlling the voltage imposed on the oscillation circuit. Using this ingenious sensor system in test plants, we can achieve favorable results in the detection and measurement of scale and slime.

The lethal action of high pressure on the cells suspended in M/15 buffer was appreciably counteracted by 8/15 M buffer but not by 8/15 M NaCl solution.

The digest had no binding activity toward five kinds of anti-β-lactoglobulin monoclonal antibodies with distinct epitope specificity, while it contained the full content of α-lactalbumin. The result shows that moderately high pressures could be useful to control enzymatic proteolysis and to selectively digest the useless proteins contained in food.

The surface tension (σ) of batter prepared with one or two of the major ingredients of wheat flour, egg and sucrose was measured by the maximum bubble pressure method. The surface tension of the soft- and hard-wheat flour suspension decreased as the solid content of wheat flour was increased, finally reaching 48.2 and 52.7 dyn/cm, respectively. The surface tension of the wheat flour suspension was lower than that of its supernatant, which suggests that the precipitate reduced the surface tension. Gelatinization of the wheat flour suspension lowered its surface tension. The surface tension of the whole egg dispersion decreased markedly to about 53 dyn/cm as the solid concentration was increased from 0 to 1%, and remained almost constant as the concentration was increased further. This tendency was almost the same as that of the egg yolk dispersion. The surface tension of mixtures of two ingredients such as egg and wheat flour, and egg and sucrose was almost equal to that of the ingredient with the lower surface tension at the same concentration as in the mixture.

This investigation was carried out to learn whether or not tryptophan-niacin conversion is affected by the type of tryptophan, namely protein, small peptides, and mixtures of amino acids. Growing rats were fed with a nicotinic acid-free diet containing 20% egg white (EW; tryptophan content, 0.2085%), 25% egg white proteolysate-5 (EWP-5; tryptophan content, 0.2087%), or 18.13% mixtures of amino acids (AA; tryptophan content, 0.2085%) for 10 days. Urine samples were collected on the last day of the experiment. The body weigh gain and food intake during the experiment were almost the same among the animals in the three groups, and the content of total nicotinamide in the liver in the three groups was within the normal range. Under these conditions, the apparant tryptophan-niacin conversion [urinary excretion of nicotinamide +

In order to evaluate the species-dependent difference in the protective effect of dietary fiber against amaranth (Food Red No. 2) toxicity, rats and chicks were fed with a large amount (5 to 6% of the diet) of amaranth with or without the addition of 5% dietary fiber in diets containing different carbohydrates. The dietary fiber (GDF) was prepared from "gobo, " the roots of edible burdock (
Arctium lappa L.). Feeding amaranth together with the raw corn starch, sucrose, maltose or glucose diet to rats caused severe diarrhea, enlargement of the cecum, and decreased body weight gain and feed efficiency. However, rats concurrently fed with 5% amaranth and 5% GDF were almost free from these adverse effects of amaranth irrespective of the dietary carbohydrates. In contrast with rats, there was little or no growth retardation in chicks when fed with 6% amaranth in the mono- and disaccharide-based diets. Only when 6% amaranth was added to the corn starch diet did the chicks show reduced body weight gain to a statistically significant extent. However, the depression of growth rate by amaranth was not ameliorated in the chicks even when the amaranth-containing diet was supplemented with 5% GDF. From these results, it is suggested that chicks are less susceptible to amaranth toxicity than rats, and that they are different from rats in the mechanism by which dietary fiber exerts its beneficial effect on amaranth toxicity.

Drainage in foam was analyzed by the capillary model proposed by Haas and Johnson. Foam was produced by introducing air into an oval hum in solution through a spinneret. The electric conductivity at selected positions in the foam and the drained liquid height below the foam were measured at constant intervals. The measured electric conductivity was converted to the liquid volume fraction by Prager's equation. The capillary model described well not only the liquid leakage rate from foam but also the liquid volume fraction in foam. The ratio of the liquid volume fraction in foam to the volume fraction of the Plateau border was much larger than the value estimated from Haas and Johnson's result. It was confirmed that a time constant,
T, involved in the model was suitable for estimating foam stability only by one parameter. However,
T is affected not only by material characteristics but also by the foam height. On the other hand, since the ratio of the liquid volume fraction in foam to the volume fraction of the Plateau border reflects the material characteristics, it may be used for comparing the foam stability between materials with the same viscosity and density.

3 cells/g after 30 days of fermentation. The fermentation mixture did not putrefy. The liberation rate and yield of total amino acids and glutamic acid from raw materials obtained by the SY addition method were greater than or the same as those of the ethanol addition method, and were higher than those obtained by the NaCl addition method. This method can be used by replacing glucose with starch as an ethanol source and by replacing soy beans with sardine fish meat.

Synthetic moracin M, 2-(3', 5'-dihydroxyphenyl)-6-hydroxybenzofuran (4), as the basic skeleton of moracins, indicated weak activity as an oviposition stimulant. The increase in susceptibility of already-infested mulberry leaf is discussed in relation to the production of phytoalexins. All these compounds except ω-hydroxy moracin N (3) are known as phytoalexins in the mulberry tree.

The effect of overnight fasting on the dietary protein-dependent change in the fatty acid composition of tissue lipids was studied in rats fed with casein or soybean protein (20%) diets containing 5 or 2% corn oil. The activity of the Δ6-desaturase of liver microsomes, a key enzyme of linoleate metabolism to arachidonate, was depressed significantly by overnight fasting, and the protein effect disappeared, irrespective of the level of dietary fat. The proportion of linoleate in liver phosphatidylcholine was decreased, whereas that of arachidonate was increased after overnight fasting in rats fed with a low fat diet, resulting in an elevation of the linoleate desaturation index. Although the effect of fasting became obscure on a high fat diet, the protein effects were maintained even after fasting. A similar trend was also observed in various lipid fractions. Thus, the effect of dietary protein on the polyunsaturated fatty acid profile was not modulated by overnight fasting, particularly when a minimal amount of linoleic acid was supplied.

The N-terminal amino acid sequence predicted was identical with the sequence of the first 20 N-terminal amino acid residues of the protein obtained by Edman degradation. Comparison of the predicted amino acid sequence of E1 protein with those of the four other known β-D-fructofuranosidases from
