Abstract

Agroindustry is a major supplier of biomass so far not satisfactorily used, being responsible for a large portion of the so-called industrial waste. The high availability of lignocellulosic fibers opens up a great opportunity for technological advances that add value to the products of the agribusiness. For example, the production of alcohol from lignocellulosic residues has been considered, worldwide, as a viable way of producing a fuel that would replace petroleum-derived fuels. Among the ligninolytic enzymes (laccases, lignin peroxidase, manganese peroxidase and versatile peroxidase), laccases seem to be the most suitable enzymes to be used on large scale in the transformation of lignocellulosic fibers thanks to the existence of a considerable number of producing microorganisms, to the ease of production of these enzymes through submerged cultures and in solid state, the broad substrate specificities of the laccases and their ability to use atmospheric oxygen as an electron donor. Laccases are enzymes capable of DOI: https://doi.org/10.31692/IICIAGRO.0157

甘蔗甘蔗渣经不同漆酶预处理后，酶的糖化程度提高

农业工业是迄今未得到满意利用的生物质的主要供应者，造成了很大一部分所谓的工业废物。木质纤维素纤维的高可用性为技术进步开辟了一个巨大的机会，为农业综合企业的产品增加了价值。例如，在世界范围内，从木质纤维素残留物中生产酒精被认为是生产替代石油衍生燃料的一种可行方法。在木质素分解酶(漆酶、木质素过氧化物酶、锰过氧化物酶和多功能过氧化物酶)中，漆酶似乎是最适合大规模用于木质纤维素纤维转化的酶，这是因为存在相当数量的生产微生物，而且这些酶易于通过液体培养和固态生产。漆酶广泛的底物特异性和它们利用大气中的氧作为电子供体的能力。漆酶是一种能够处理DOI: https://doi.org/10.31692/IICIAGRO.0157的酶
