Keywords

Saccharomyces Cerevisiae, Ergosterol, Fermentation, Fed-Batch

Abstract

The parameters during ergosterol fermentation were studied. The relationship between dissolved oxygen, our, ph and residual sugar concentration and the biomass and ergosterol content of Saccharomyces cerevisiae were compared, and the intrinsic relationship between these parameters was studied. Research shows that dissolved oxygen can more accurately reflect the growth status of yeast and is a better control parameter in the fermentation process. Controlling dissolved oxygen at about 12% can effectively increase the production of ergosterol per unit volume of fermentation broth.

Variant Memes, Strong Memes, Weak Memes, Alienation, Naturalization

Abstract

In today’s era of information globalization and economic integration, global culture is increasingly integrated. As a bridge of cross-cultural communication, translation not only conveys language information, but also conveys cultural information. From a completely new perspective, the translation process is defined as the process of meme variation, and the target language memes are defined as “variant memes”. Through analysis, it is concluded that “variant memes” also include strong memes and weak memes. reasons, and gives a new definition of powerful memes in “variant memes”. Then, it explores how to effectively use foreignization and domestication translation methods in translation from the perspective of strong memes and weak memes. After analysis of a large number of examples, it is concluded that in the translation process, if the “variant memes” obtained through foreignization are strong memes, the foreignization translation method should first be considered. If they are weak memes, the domestication translation method or foreignization and domestication should be used. combined approach.

Keywords

Yellow-Haired Rat, Cabergoline, Infertility Control, Social Behavior

Abstract

Abstract Sterility control can not only directly reduce the fertility rate of pest rat populations, but also affect individual social behavior, causing changes in hierarchical relationships and social structures within the population, thereby interfering with population reproduction. In order to explore the effects and duration of effect of different doses of cabergoline on the behavior of male rats, healthy male yellow-haired rats were intragastrically administered with 50 mg/kg and 100 mg/kg cabergoline, and on the 1st and 1st days after administration. Encountered with normal male rats on the 18th day, and encountered normal female rats on the 4th and 21st days, compared before administration (encountered with normal male rats and female rats on the 4th and 1st days before cabergoline administration respectively) and differences in individual behavior after administration. The results showed that: cabergoline reduced the time for male rats to explore and attack normal male rats, and reduced the time and frequency of male rats to attack normal female rats; 100 μg/kg cabergoline reduced the frequency of male rats to explore normal female rats. , and the frequency of grooming and resting of male rats was significantly reduced. This indicates that cabergoline can interfere with the social behavior of yellow-haired rats toward individuals of the same and opposite sex. In addition, on the 18th and 21st days after drug treatment, the social behavior of male individuals, same-sex and opposite-sex individuals was not significantly different from that before treatment, indicating that the effect of the drug on behavior will gradually disappear with time after drug withdrawal.

The Occurrence Of Ergot Disease In Some Grass Plants And The Characteristics Of Its Pathogenic Fungi

dina L-(+)-Ergothioneine, Uncategorized

Keywords

Ergot Disease, Grass Grass, Transmission, Fungicide

Abstract

The ergot fungus Claviceps sp. that infects grass plants not only causes ergot disease in plants and reduces crop yields, but also causes poisoning of humans and livestock. In central Xinjiang and parts of eastern Qinghai, ergot disease has been found in grasses of three groups and five genera that livestock like to eat. In some areas, the incidence rate is as high as 65%. Insects such as ladybugs, blowflies and ants are also active on the diseased plants. The study obtained 18 isolated strains from 6 species of Gramineae diseased plants in 5 genera, and observed the colony morphology, growth rate, spore morphology and size of the isolated strains. These cultural characteristics and morphological characteristics are similar to the asexual generation of the fungus Sphacelia of the genus Claviceps. By studying the sensitivity of these isolated strains to pesticides, it was found that carbendazim had a significant inhibitory effect on the bacteria. It is worth noting that ergot disease of grasses occurs on a large scale in tourist areas and pastoral areas.

Discussion On The Expanded Functional Sulfur Requirements Of Rapeseed Leaves And Its Use As A Diagnosis Of Sulfur Deficiency

dina L-(+)-Ergothioneine, Uncategorized

Keywords

Functional Sulfur Requirement, Rapeseed, Leaf Expansion

Abstract

An artificial climate chamber was used to conduct a controlled flow experiment on Canola (Brassicanapus L.) at the seedling stage to explore the effects of insufficient sulfur supply on the dynamic changes of different plant growth parameters. The results showed that the change of leaf area per unit weight (i.e. A/W) is the most sensitive indicator parameter reflecting the sulfur nutritional status of plants. Based on the changes in relative yield increase rate, the functional sulfur (S) requirement for rape leaf expansion was calculated to be 0.32%. This value can more effectively reflect the sulfur abundance and deficiency status of the plant (organ) than the traditional method, that is, the critical value calculated by using the change in dry matter weight (DM) of the whole plant or a certain organ. When the supply of sulfur, which has weak reuse ability, is insufficient, the first thing to be affected is the expansion rate of young leaves, and the dry matter of the plant (or leaves) is often affected by the net assimilation rate (EA) and relative growth rate (RW). A relative increase occurs within a certain period of time after sulfur deficiency, resulting in a cumulative effect. Therefore, the expanded functional sulfur requirement of rapeseed leaves can be used as a diagnostic indicator of sulfur deficiency in rapeseed.
