    Agarwood is a wood containing resin from Agarwood, a plant of the family Aquilaria, is a traditional precious Chinese medicine and natural spice in China, Japan, India, Southeast Asia and other countries.
    Bai Muxiang can produce agarwood resin only when it is damaged by the outside world or infected by fungi.
    With the development of the agarwood market, the natural habitat of agarwood plants has been severely damaged, and now Baimuxiang has been listed as a national secondary endangered plant.
    In order to continuously utilize the resources of agarwood, the rapid aroma-forming technology has become the most effective way to increase the yield of agarwood, such as the microbial aroma method.
    Although the microbial aroma method has been proven to significantly increase the yield of agarwood, the function of new fungal resources and their fermentation products that promote aroma formation remains to be studied.

    Recently, Xu Jianchu and Wang Yuehu's team from Kunming Institute of Botany, Chinese Academy of Sciences published their latest research results in the journal Life.
    The team discovered a new species of agarwood endophytic fungus through agarwood samples collected in Yunnan.
    Based on the analysis of morphology and phylogeny, it was finally identified as two new species of the genus C.
    agaricula and C.
    yunnanensis.

    After further analysis of the components of the two new species of fermentation products, it was found that 4 out of the 5 sesquiterpenoids produced by the Agarwood bacteria are the reported volatile components of Agarwood, which indicates that the Agarwood bacteria are useful for catalysis.
    The potential of white wood incense to form fragrance.
    At the same time, the research also optimized the liquid fermentation conditions of Agarwood carbonaceous bacteria, and selected three culture media (MEB, PDB and RB) suitable for cultivating high-quality and high-yield Agarwood carbonaceous bacteria.

    This study revealed the interaction between endophytic fungi metabolites and host plants, laying a foundation for the application of endophytic fungi to build aroma and the use of endophytic fungi to promote aroma quality.
