The main objective of the applicant's research program is to advance and carry out experimental work that should contribute to the understanding of the mechanistic action and biocatalysis in non-conventional media (NCM), in particular organic solvent media (OSM) and solvent free media (SFM), of selected immobilized enzymes of microbial origin. Although the research work carried out by the applicant addressedthe immobilization and biocatalysis of lipoxygenase/hydroperoxide lyase, the stability of these enzymes as well as the elucidation of their mechanistic action in NCM are still among the major challenges to be overcome. The acquired knowledge and experience in our laboratory in immobilization and biocatalysis of enzymes in non-conventional media led us to move to novel horizons in research, in particular the use of novel nanotechnology approach for enzyme immobilization as well as the modeling and bioinformatics for setting the experimental design for the elucidation of their structure-function in non-conventional media.

申请人研究计划的主要目的是进步和开展实验性工作，这些工作应有助于理解非惯性培养基（NCM）的机械作用和生物催化，特别是有机溶剂溶剂介质（OSM）和溶剂溶液的无培养基（SFM）（SFM），对所选的固定型微生物酶的微生物酶。尽管申请人进行的研究工作解决了脂氧酶/氢过氧化物裂解酶的固定和生物催化，但这些酶的稳定性以及其在NCM中的机械作用阐明仍然是要克服的主要挑战之一。我们在非惯性媒体中固定和生物催化的实验室中获得的知识和经验，使我们在研究方面迈向了新的范围，特别是使用新型的纳米技术方法来固定酶以及建模和生物信息学以设定其结构实现媒体的实验设计。
