3-Methylxanthine production through biodegradation of theobromine by Aspergillus sydowii PT-2.
Zhou B, Ma C, Zheng C, Xia T, Ma B, Liu X. Zhou B, et al. BMC Microbiol. 2020 Aug 27;20(1):269. doi: 10.1186/s12866-020-01951-z. BMC Microbiol. 2020. PMID: 32854634 Free PMC article.
Previous studies confirmed that several microbial isolates from Pu-erh tea could degrade and convert caffeine and theophylline. We speculated that these candidate isolates also could degrade and convert theobromine through N-demethylation and oxidation. ...

Comparison of characteristic components in tea-leaves fermented by Aspergillus pallidofulvus PT-3, Aspergillus sesamicola PT-4 and Penicillium manginii PT-5 using LC-MS metabolomics and HPLC analysis.
Ma C, Li X, Zheng C, Zhou B, Xu C, Xia T. Ma C, et al. Food Chem. 2021 Jul 15;350:129228. doi: 10.1016/j.foodchem.2021.129228. Epub 2021 Feb 10. Food Chem. 2021. PMID: 33618088
Microbiota influenced quality formation of ripened Pu-erh tea. To understand the effect of each tea-derived fungal strain, tea-leaves were fermented by Aspergillus pallidofulvus PT-3 (ApaPT), Aspergillus sesamicola PT-4 (AsePT) and Penicillium manginii PT-5 (PmaPT), respec …
