Several yeasts, which are eukaryotic microorganisms, have long been used in different industries due to their potential applications, both for fermentation and for the production of specific metabolites. Kluyveromyces marxianus is one of the most auspicious nonconventional yeasts, generally isolated from wide-ranging natural habitats such as fermented traditional dairy products, kefir grain, sewage from sugar industries, sisal leaves, and plants. This is a food-grade yeast with various beneficial traits, such as rapid growth rate and thermotolerance that make it appealing for different industrial food and biotechnological applications. K. marxianus is a respiro-fermentative yeast likely to produce energy by either respiration or fermentation pathways. It generates a wide-ranging specific metabolites and could contribute to a variety of different food and biotechnological industries. Although Saccharomyces cerevisiae is the most widely used dominant representative in all aspects, many applications of K. marxianus in biotechnology, food and environment have only started to emerge nowadays; some of the most promising applications are reviewed here. The general physiology of K. marxianus is outlined, and then the different applications are discussed: first, the applications of K. marxianus in biotechnology, and then the recent advances and possible applications in food, feed and environmental industries. Finally, this review provides a discussion of the main challenges and some perspectives for targeted applications of K. marxianus in the modern food technology and applied biotechnology in order to exploit the full potential of this yeast which can be used as a cell factory with great efficiency.

几种作为真核微生物的酵母因其潜在的用途而长期用于不同的行业，既可用于发酵，又可用于生产特定的代谢产物。马克斯克鲁维酵母是最吉祥的非常规酵母之一，通常从广泛的自然栖息地分离，例如发酵的传统乳制品，开菲尔谷物，制糖业的污水，剑麻叶和植物。这是一种具有各种有益特性的食品级酵母，例如快速生长速度和耐热性，使其吸引不同的工业食品和生物技术应用。马克斯K.是一种呼吸发酵酵母，可能通过呼吸或发酵途径产生能量。它产生范围广泛的特定代谢产物，并可能有助于各种不同的食品和生物技术产业。尽管酿酒酵母在各个方面都是使用最广泛的优势代表，但如今马克斯克鲁维酵母在生物技术，食品和环境中的许多应用才刚刚出现。这里回顾了一些最有前途的应用程序。概述了K. marxianus的一般生理学，然后讨论了其不同的应用：首先，K。marxianus的应用生物技术领域，然后是食品，饲料和环境行业的最新进展和可能的应用。最后，这篇综述讨论了K. marxianus在现代食品技术和应用生物技术中的目标应用面临的主要挑战和一些观点，以便充分利用这种酵母的潜能，该酵母可以高效地用作细胞工厂。 。
