专利号:US-11744867-B2 优先权日:2017-02-14 标 题 :Modulation of microbial synthesis of 4-ethylphenol and 4-ethylphenyl sulfate in behavior and disease 发明人:NEEDHAM BRITTANY D; MAZMANIAN SARKIS K; SHARON GIL; FUNABASHI MASANORI; FISCHBACH MICHAEL A; HSIAO ELAINE Y; PATTERSON PAUL H 权利人:CALIFORNIA INST OF TECHN; UNIV CALIFORNIA 摘要:Some embodiments relate to genetically engineered bacterial strains for modulation of levels of the bacterial metabolite 4-ethylphenol (4EP) and its sulfated form, 4-ethylphenyl sulfate (4EPS). In some embodiments, the bacteria reduce or inhibit production of 4EP or 4EPS in the gut of a subject. The bacteria can ameliorate, delay the onset, or reduce the likelihood of one or more symptoms associated with anxiety and/or autism spectrum disorder (ASD) in the subject.
专利号:US-11447742-B2 优先权日:2016-02-09 标题 :Compositions and methods for activation and overexpression of secondary metabolites in microorganisms 发明人:HAMILL DAKOTA BENJAMIN; COTTER JAKE J 权利人:PROSPECTIVE RES INC 摘要:Methods and compositions herein provide non-naturally occurring γ-butyrolactones (GBLs) in racemic mixtures that increase efficiency and effectiveness of screening for production of antibiotics, and enhance yields and express silent pathways. Non-naturally occurring GBLs were synthesized and found to stimulate antibiotic production in several different streptomycete strains. Antibiotic production by Streptomyces coelicolor was induced by a racemic mixture of non-cognate stereoisomers of VB-D, seven of which are non-naturally occurring. Further, novel A-factor-type GBL analogs stimulated antibiotic production in S. coelicolor . Synthesis in response to the treatment with the non-cognates GBL was observed for known compounds including undecylprodigiosin, desferrioxamine and streptorubin B, as was synthesis of a compound of unknown structure. A group of 37 additional microbial strains was screened by principal component analysis to determine optimal concentrations of each of a panel of four non-cognate synthetic GBLs for addition to cultures with optimal stimulation of secondary metabolites, and large scale fermentations were analyzed and product enhancement by the GBLs was observed.
