标题:Sequences for production of 2,4-diacetylphloroglucinol and methods
发明人：THOMASHOW LINDA S; BANGERA MAHALAXMI; WELLER DAVID M; COOK R JAMES
权利人:US AGRICULTURE; UNIV WASHINGTON
摘要:DNA sequences which function specifically in the synthesis of 2,4-diacetylphloroglucinol (Phl) are described. The sequences include phl genes which encode phl gene proteins and coding and regulatory sequences for production of Phl as well as sequences containing phl genes, which sequences have the capability of conferring or enhancing Phl biosynthetic capability in bacterial strains. The transformed strains are useful as biocontrol agents against fungal pathogens.

权利人:PROCTER & GAMBLE
摘要:Personal care compositions, such as oral care and skin care compositions containing a flavor/perfume system comprising one or more coolants. The pleasant cool sensation provided by a coolant is enhanced in terms of quicker onset, greater intensity, impact or longer duration, which improves appeal and acceptability of the compositions to consumers.
