摘要
鸡蛋蛋清具有独特的物理特性和丰富的化学因子,有可能在防止微生物感染、保证卵黄内营养物质免受破坏、保持胚胎活性等方面发挥重要作用。本研究以孵化早期鸡胚蛋蛋清为研究对象,深入挖掘孵化蛋清抗菌特性及其作用机制,旨在揭示蛋清抗菌因子在孵化条件下的作用特点及相互作用关系。主要开展以下三个方面的研究:(1)孵化早期蛋清抗菌防御体系变化及其对鸡蛋蛋清抗菌功能的影响;(2)孵化早期蛋清抗微生物防御作用机制研究;(3)蛋清蛋白质抗菌相互作用关系研究。具体研究内容和结果如下:
     研究测定了孵化早期蛋清基本理化性质及体外抗菌活性的变化。结果表明,蛋清pH值在孵化约48h后上升至最高值,而蛋白高度下降到最低值;之后,蛋清pH值开始降低,蛋清开始浓缩,浓蛋清及稀蛋清粘度均快速上升。孵化早期蛋清的理化性质的变化直接影响蛋清的体外抗菌功能。孵化第2d胚蛋蛋清抗菌功能明显增强,尤其是抑制革兰氏阴性菌肠炎沙门氏菌的作用。孵化2d后,随孵化时间的延长,胚蛋蛋清的抑菌功能明显减弱,到孵化第5d时,胚蛋蛋清抑制革兰氏阴性菌的作用能力几乎消失。
     卵转铁蛋白和溶菌酶是蛋清内含量最丰富的两种抗菌功能性蛋白质。研究通过SDS-PAGE和RP-HPLC技术对不同孵化阶段蛋清内卵转铁蛋白和溶菌酶含量及活性变化进行了测定。结果显示,随着孵化时间的延长,卵转铁蛋白的浓度不断增加,而溶菌酶的浓度变化很小。表明溶菌酶在禽蛋孵化早期可能存在一定程度上的降解。蛋清总铁结合力不断增强,在孵化第5d时,达到最高值23.78±0.65mg/mL。蛋清溶壁活性在孵化Od时约为30397±2280U/mg,孵化2天后降至15036±2574U/mg。随后,蛋清溶壁活性开始缓慢增加,这种变化可能与孵化蛋清内动态变化的pH有关。
     研究采用凝胶层析结合MALDI-TOF MS技术对孵化早期蛋清内小分子量(LMW)蛋白质(肽)组成变化进行监测,从而揭示孵化早期蛋清蛋白质体系的稳定性。研究显示,孵化早期蛋清内LMW蛋白质组成是高度动态变化的。孵化早期(0~5d)蛋清内共出现114个LMW蛋白质信号峰,荷质比分布范围为1035.88~7112.91m/z,不同孵化阶段蛋清内LMW蛋白质组成差异很大。其中,共有28、26、35、35、20、17种LMW蛋白质分别出现在孵化0d、1d、2d、3d、4d、5d蛋清内。研究证实,孵化早期蛋清内部分大分子蛋白质会发生降解。
     孵化早期浓蛋清的液化、粘度的下降可能与蛋清内部蛋白质分子间的相互作用或蛋白质的降解有关。比较研究孵化早期浓稀蛋清抗菌特性发现:孵化早期浓蛋清与稀蛋清pH、溶菌酶、卵转铁蛋白含量无明显差异。浓稀蛋清转铁活性、溶壁活性、抗菌活性的变化趋势一致。孵化早期蛋清的液化可能减弱其物理防御作用,甚至导致蛋清抗菌蛋白质溶菌酶的降解或影响蛋清内部蛋白质间的相互作用关系,然而孵化过程中形成的碱性pH环境及逐渐增强的卵转铁蛋白活性可能弥补这种减弱作用。
     采用cFDA和PI染料对孵化蛋清作用后的肠炎沙门氏菌进行荧光染色,并在荧光显微镜下进行检测分析。结果表明,在蛋清的环境应激之下,肠炎沙门氏菌表现出三种生存状态:活菌、死菌、膜受损状态。采用流式细胞仪技术对不同群体特征的菌群进行定量分析发现,不同孵化阶段蛋清抑制肠炎沙门氏菌的作用效力存在较大差异。蛋清抑制肠炎沙门氏菌的主要作用机制可能是破坏细菌膜结构,这种作用在孵化温度条件下得到增强;孵化过程中形成的碱性pH环境能够促进蛋清破坏细菌膜结构的作用效力。
     通过SEM技术观察孵化蛋清作用后肠炎沙门氏菌细胞形态结构变化发现,细菌细胞表面表观结构发生变化。采用细胞活性荧光探针(SYT09/PI)对孵化蛋清处理后的肠炎沙门氏菌菌群进行荧光染色后发现,经孵化蛋清处理后的细菌群体呈现红、绿两种荧光,进一步证明孵化蛋清能够对肠炎沙门氏菌膜结构产生损伤,使其在蛋清内呈现不同的活性状态。研究采用流式细胞仪技术对经蛋清处理后呈现不同活性状态的细菌群体进行定量分析。结果表明,与新鲜鸡蛋蛋清相比,孵化1d、2d、3d鸡蛋清对肠炎沙门氏菌膜结构的破坏作用能力均有所增强。其中,孵化2d蛋清作用效力最强。孵化早期蛋清还能够抑制肠炎沙门氏菌hilA基因的表达,减弱其黏附及入侵Caco-2细胞活性。
     采用细菌活性荧光探针(SYT09/PI)标记技术结合流式细胞仪技术,体外模拟研究了蛋清抗菌因子卵转铁蛋白、溶菌酶在孵化早期过程中的协同抗菌作用效果。研究发现,在体外条件下,卵转铁蛋白能够破坏肠炎沙门氏菌的膜结构;溶菌酶抑制肠炎沙门氏菌的作用能力相对较弱。当环境pH增加时,卵转铁蛋白、溶菌酶抗肠炎沙门氏菌的作用活性均增强。卵转铁蛋白与溶菌酶联合使用时,对肠炎沙门氏菌具有协同抗菌作用,并且碱性pH(9.5)条件能够促进两者的协同抗菌作用效果。卵白蛋白本身不具备抑制肠炎沙门氏菌的作用效果,然而在碱性条件下,卵白蛋白的浓度变化能够影响溶菌酶及卵转铁蛋白的协同抗菌作用效果。可见,孵化早期禽蛋蛋清蛋白质及其作用环境之间存在复杂的抗菌相互作用关系。
Egg albumen has unique physical and chemical properties and contains a network of defenses against microbial infection. It was considered to play an important role in antibacterial defence of the egg yolk and the avian embryo. The antimicrobial system can be activated by incubation due to the changes of physical and chemical properties of egg albumen during egg incubation. The research object of this diploma paper was egg albumen collected from the early incubation stages. And the purpose of this research was to reveal the underline antimicrobial mechanisms and the interaction relationship of egg albumen proteins during early incubation. Including the studies:(1) The changes of antibacterial system and antibacterial activity of egg albumen during egg incubation.(2) The antimicrobial mechanisms of action of egg albumen during egg incubation.(3) In vitro study of the antimicrobial proteins network of egg albumen. Specific content and the results are as follows:
     The changes in basic properties and in vitro antimicrobial activity of egg albumen during early incubation were determined. The result has shown that the pH of egg albumen was increased and reached its highest level after48hours incubation while the albumen height decreased to the lowest. Afterwards, the pH was decreased slowly and the viscosity of thick and thin egg albumen increased rapidly. The antimicrobial activity of egg albumen was also changed during the early incubation. The egg albumen collected from the second day of incubation has shown a significant increase of antimicrobial activity, especially to Salmonella enteritidis. However, the antimicrobial activity of egg albumen was decreased as incubation progressed. The antimicrobial effects of egg albumen on gram-negative bacteria would almost disappear after5days of incubation.
     The most abundant and well characterized antimicrobials in egg albumen are ovotransferrin and lysozyme. The changes of ovotransferrin and lysozyme content in egg albumen were quantified via high-performance liquid chromatography (HPLC). The results showed that the concentration of ovotransferrin in egg albumen was increased closely with the time of incubation but that of lysozyme remained substantially unchanged and was very similar to that of the non-incubated eggs. We supposed that egg incubation conditions may result in the degradation of lysozyme content. In contrast to lysozyme, ovotransferrin content has shown higher stability during the early incubation periods. The iron ion binding capacity and specific lysozyme activity of the egg albumen during early incubation stages was also investigated. The concentration of ovotransferrin determined on the iron-binding capacity was increased gradually and reached nearly23.78±0.65mg/mL after5days of incubation, which implied an increased iron binding capacity. The specific lysozyme activity in egg albumen decreased from30397±2280to15036±2574U/mg during the first two days of incubation. However, in the later stages of incubation, an increase of the enzymatic activity has been found. We inferred that the possible reason for the changes of lysozyme activity in egg albumen during incubation may be due to the dynamic changes of pH in egg albumen.
     To further understand the stability of egg albumen proteins during early incubation, an off-line peptidomics approach combining gel chromatography and MALDI-TOF MS was used to map the low molecular weight (LMW) protein profile of egg albumen during early incubation. The observed changes in the LMW protein profile during development were highly dynamic.114mass signal peaks of LMW proteins ranging from1,035.88to7,112.91m/z were detected during the early incubation stages (0-5d). Among them,28,26,35,35,20, and17peaks of proteins were present specifically in egg albumen within0,1,2,3,4,5days of incubation. The research result has confirmed that some large molecular weight proteins would degraded into small fragments during the early incubation stages.
     Carboxyfluorescein diacetate (cFDA) and propidium iodide (PI) were used in this study to determine the changes of physiological state of Salmeonella enteritidis cells treated by egg albumen. Following egg albumen treatment, Salmonella enteritidis was discriminated into three subpopulations by Fluorescence microscopy and Flow cytometric assessment:viable, dead and membrane-compromised cells. The incubation temperature and pH were both significant factors in anti-Salmonella enteritidis properties of egg albumen. Besides, the main target for antimicrobial factors in egg albumen on Salmonella enteritidis cells would be membrane integrity and the action mechanism of egg white was bacteriostatic rather than bactericidal effect during early incubation.
     The morphological changes of Salmeonella enteritidis cells treated with egg albumen were investigated by using SEM. The result showed that bacteria cells grown in incubated egg albumen were abnormal in shape and size indicating a disruption of the membrane integrity. As to Salmeonella enteritidis cells treated with incubated egg albumen and double-stained with SYTO9and PI, both green and red fluorescence can be detected. These studies confirmed previously mentioned idea that the main target for antimicrobial factors in incubated egg albumen on Salmonella enteritidis cells would be membrane integrity. Flow cytometric technique was used to quantify different bacteria subpopulations treated with egg albumen incubated for different periods. The result showed that the ability of egg albumen to disrupt bacteria membrane integrity would changed as incubation progressed and the egg albumen incubated for two days has shown to possess the most strong ability. At the same time, egg albumen from the early incubation stages could inhibit the expression of hilA gene of Salmonella enteritidis and minimize its adhesion and invasion activity to Caco-2cell.
     The synergistic antimicrobial activity of ovotransferrin and lysozyme to Salmonella enteritidis was determined by using the SYTO9/PI double staining technique in combination with flow cytometry. The result showed that ovotransferrin could disrupt the membrane integrity of Salmonella enteritidis cells and the inhibitory effect of lysozyme to Salmonella enteritidis was weak. Alkaline pH would enhance the antimicrobial activities of ovotransferrin and lysozyme to Salmonella enteritidis and promote the synergistic antimicrobial activity of them. Ovalbumin was the most abundant protein in egg albumen which constitutes a special protein environment for the antimicrobial proteins. It showed little antimicrobial activity on Salmonella enteritidis. However, we found that ovalbumin increased the synergistic activities of ovotransferrin and lysozyme under alkaline pH, which indicated that a complicated interaction relationship was existed between egg albumen proteins and albumen physicochemical environment during egg incubation.
