Abstract

BACKGROUND

Beta-glucan (β-glucan) is a polysaccharide containing β-glycosidic bonds that is an important structure part of different yeast cells.

AIM

The purpose of the study is to characterize β-glucan obtained from isolated from caprine mastitis

METHODS

The β-glucan was extracted by using utilizing an Alkaline-acidic extraction technique. The dry weight of extracted β-glucan was 7.47/150 g with 4.98%.

RESULTS

The findings demonstrated that the extracted β-glucan had similarity in the primary peak 5.78 of liquid samples using the method of high-performance liquid chromatography when compared to the standard form of β-glucan. However, scanning electron microscopy studies revealed that the standard of β-glucan was distinct in morphology but similar to β-glucan isolated from in terms of particle sizes in the range of 1.60-2.65 m and the lack of cell wall traces. The findings of an investigation using energy-dispersive X-ray fluorescence spectroscopy (EDS/EDX) of extracted and standard β-glucan, showed the principal elements discovered were carbon (C), oxygen (O), and nitrogen (N). Aluminum (Al), silicon (Si), nickel (Ni), and gold (Au) were also present, but in less amounts.

CONCLUSION

The extracted β-glucan displayed a high degree of similarity and purity to the standard β-glucan, according to the findings of Fourier transform infrared spectroscopy (FT-IR) research.

摘要

背景

β-葡聚糖(β-glucan)是一种含有β-糖苷键的多糖,是不同酵母细胞的重要结构部分。

目的

本研究的目的是表征从山羊乳腺炎中分离得到的β-葡聚糖。

方法

采用碱性-酸性提取技术提取β-葡聚糖。提取的β-葡聚糖干重为 7.47/150 g,得率为 4.98%。

结果

研究结果表明,与β-葡聚糖标准品相比,利用高效液相色谱法对液体样品进行检测时,提取的β-葡聚糖在主峰 5.78 处具有相似性。然而,扫描电子显微镜研究表明,标准β-葡聚糖在形态上与从乳腺炎中分离得到的β-葡聚糖相似,但在粒径范围为 1.60-2.65 μm 时,没有细胞壁痕迹。通过能量色散 X 射线荧光光谱法(EDS/EDX)对提取的和标准β-葡聚糖进行研究的结果表明,发现的主要元素是碳(C)、氧(O)和氮(N)。还存在铝(Al)、硅(Si)、镍(Ni)和金(Au),但含量较少。

结论

根据傅里叶变换红外光谱(FT-IR)研究的结果,提取的β-葡聚糖与标准β-葡聚糖具有高度的相似性和纯度。
