Ultrasound has been applied for varied purposes as it provides additional mechanical energy to a system, and is still profitable and straightforward, which are advantages for industrial applications. In this work, ultrasonic treatments were applied to purified collagenase fractions from a fermented extract by Aspergillus terreus UCP 1276 aiming to evaluate the potential effect on collagen hydrolysis. The physical agent was evaluated as an inductor of collagen degradation and consequently as a producer of peptides with anticoagulant activity. The sodium dodecyl sulphate-polyacrylamide gel electrophoresis analyses were also carried out to compare the hydrolysis techniques. The ultrasound (40 kHz, 47.4 W/L) processing was conducted under the same conditions of pH and temperature at different times. The ultrasound-assisted reaction was accelerated in relation to conventional processing. Collagenolytic activity was enhanced and tested in the presence of phenylmethanesulfonyl fluoride inhibitor. Underexposure, the activity was enhanced, reaching more than 72.0% of improvement in relation to the non-exposed enzyme. A period of 30 min of incubation under ultrasound exposure was enough to efficiently produce peptides with biological activity, including anticoagulation and effect on prothrombin time at about 60%. The results indicate that low-frequency ultrasound is an enzymatic inducer with likely commercial applicability accelerating the enzymatic reaction.

超声辅助酶催化胶原蛋白的水解,以产生具有生物医学潜力的肽:来自土壤曲霉UCP1276的胶原酶。

超声波已被用于各种目的,因为它为系统提供了额外的机械能,并且仍然有利可图且简单易行,这对于工业应用而言是有利的。在这项工作中,采用超声波处理法对来自曲霉曲霉UCP 1276的发酵提取物中的纯化的胶原酶组分进行了评估,目的是评估其对胶原蛋白水解的潜在影响。该物理试剂被评估为胶原降解的诱导剂,因此被评估为具有抗凝活性的肽的生产者。还进行了十二烷基硫酸钠-聚丙烯酰胺凝胶电泳分析以比较水解技术。在相同的pH和温度条件下,在不同的时间进行超声处理(40 kHz,47.4 W / L)。相对于常规处理,超声辅助反应得以加速。在存在苯基甲烷磺酰氟抑制剂的情况下,增强了胶原蛋白水解活性并进行了测试。暴露不足时,活性得到增强,相对于未暴露的酶而言,提高了72.0%以上。在超声照射下孵育30分钟的时间足以有效产生具有生物学活性的肽,包括抗凝作用和对凝血酶原时间的影响,约为60%。结果表明,低频超声是一种酶促诱导剂,可能具有加速酶促反应的商业应用性。生物电磁学。2020; 41:113-120。©2019生物电磁学会。在存在苯基甲烷磺酰氟抑制剂的情况下增强了胶原蛋白水解活性并进行了测试。暴露不足时,活性得到增强,相对于未暴露的酶而言,提高了72.0%以上。在超声照射下孵育30分钟的时间足以有效产生具有生物学活性的肽,包括抗凝作用和对凝血酶原时间的影响,约为60%。结果表明,低频超声是一种酶促诱导剂,可能具有加速酶促反应的商业应用性。生物电磁学。2020; 41:113-120。©2019生物电磁学会。在存在苯基甲烷磺酰氟抑制剂的情况下,增强了胶原蛋白水解活性并进行了测试。暴露不足时,活性得到增强,相对于未暴露的酶而言,提高了72.0%以上。在超声照射下孵育30分钟的时间足以有效产生具有生物学活性的肽,包括抗凝作用和对凝血酶原时间的影响,约为60%。结果表明,低频超声是一种酶促诱导剂,可能具有加速酶促反应的商业应用性。生物电磁学。2020; 41:113-120。©2019生物电磁学会。在超声照射下孵育30分钟的时间足以有效产生具有生物活性的肽,包括抗凝作用和对凝血酶原时间的影响,约为60%。结果表明,低频超声是一种酶促诱导剂,可能具有加速酶促反应的商业应用性。生物电磁学。2020; 41:113-120。©2019生物电磁学会。在超声照射下孵育30分钟的时间足以有效产生具有生物学活性的肽,包括抗凝作用和对凝血酶原时间的影响,约为60%。结果表明,低频超声是一种酶促诱导剂,可能具有加速酶促反应的商业应用性。生物电磁学。2020; 41:113-120。©2019生物电磁学会。
