Enzyme immobilization has demonstrated effective means for extending protein stability and shelf life. However, current methods negatively affect the enzyme activity, particularly for application purposes. Herein, the amino functionalized graphene oxide (GO–NH2) was synthesized and used to covalently immobilize lactase. FT-IR, UV-Vis, SEM, TEM and XPS were employed to confirm and characterize the immobilized lactase. At the resulting optimal temperature, the immobilization rate achieved 61% and the immobilized lactase maintained approximately 95% of catalyst activity. Compared with the free lactase, used as a control, the immobilized lactase was significantly more stable within acidic or basic environments, higher temperature conditions and had multiple recycle use characteristics. Furthermore, the immobilized lactase had a preserved 87% activity after storage at 4 °C for 30 days, while the free lactase was almost deactivated after 20 days under the same storage conditions. This work conforms that the amino-functionalized graphene oxide is a potential support material for lactase immobilization and can be extended to use with a variety of enzymes for a number of applications.

In today’s new era of digital technology-driven innovation, the continuous development of information technology has brought reforms and innovations to the education field, and has injected new vitality into the modernization of education in my country. The use of information technology to promote educational reforms is incorporated into education related policies. Innovation is the driving force of national development, and it is also the focus of international competition and talent training under the background of economic globalization. The construction of new liberal arts is an innovative development measure for China’s higher liberal arts education in the new era. It is the emphasis and requirement of liberal arts in the development of science and technology today. In the context of the new liberal arts, the training of art design professionals should be cross-integrated with computer science, information technology and other disciplines, combined with the development and needs of regional digital industries, breaking professional boundaries, and mastering cutting-edge technology on the premise of adhering to the core values of art and design education. At the same time, reconstruct the talent training model. This article elaborated on the development trend of digital and informatization of art design education in the talent training and discipline construction of the art design major, and the official team of Cocos Engine-Yaji Software to build the Cocos Digital Technology Industry College to create a new mode of efficient integration of production and education., To build a unique digital art talent training system, to effectively connect the talent chain and the industrial chain, to promote the industrialization of academic achievements, to cultivate application-oriented talents that meet the needs of the digital industry, and to promote the construction of a new liberal arts major in art design.

In recent years, the tourism industry in southern Jiangxi, which focuses on Hakka elements, is developing rapidly with a strong momentum. Hakka culture is one of the keywords of the tourism image in southern Jiangxi. The traditional Hakka needlecraft culture in southern Jiangxi is an integral part of Hakka culture. As a tourism creative industry, the traditional Hakka needlecraft culture in southern Jiangxi is regarded as a kind of afterwork. The cultural value of the industry era is affirmed, and its economic value has changed greatly. Thesand gained a new economic basis. Their value orientation is no longer the situation of “good quality and low price”, but because they are rich in humanistic value, emotional value and local characteristics. e female red cultural creative products have been re-recognized through the economic value of tourism development, And get “value for money” brand positioning, this culture has an irreplaceable role in promoting the economy, has great economic value. Compared with the “hard power” of politics and economy, culture is a “soft power”, and its influence and penetration to economy and society are continuous. Hakka needlecraft culture is a treasure of folk art in Jiangxi and even the whole Hakka family. As one of the “soft power” of culture, folk craft has the value of promoting local economic development.

Art education in colleges and universities is an important part of China’s higher education. It takes art as the content and educates people. Through educational activities, it fosters college students to form correct aesthetic concepts, improve their personal personality, and stimulate their imagination and creativity. The integration of art education into Hakka cultural inheritance has the problem of compatibility between the law of cultural inheritance and the law of education. Efforts should be made to activate static local cultural resources into dynamic educational and cultural capital. Hakka culture curriculum system should be integrated with traditional cultural characteristics and art education concepts. The contents should be closely related to art education, and the Hakka spirit of simplicity and diligence should be transmitted through the connotation of Hakka culture. The “cultural resources into curriculum resources”, “cultural elements into cultural creativity” double path teaching implementation, to achieve the value of Hakka cultural resources inheritance.
