Perturbations in gut microbiota composition in schizophrenia.

Schizophrenia is a severe, complex and long-term psychiatric disorder with unclear etiology. Gut microbes influence the central nervous system via the gut-brain axis. Consequently, investigations of the relationship between gut microbes and schizophrenia are warranted.

Biosynthesis of α-Pinene by Genetically Engineered from Low-Cost Renewable Feedstocks.

α-Pinene, an important biologically active natural monoterpene, has been widely used in fragrances, medicines, and fine chemicals, especially, in high-density renewable fuels such as jet fuel. The development of an α-pinene production platform in a highly modifiable microbe from renewable substitute feedstocks could lead to a green, economical avenue, and sustainable biotechnological process for the biosynthesis of α-pinene. Here, we report engineering of an orthogonal biosynthetic pathway for efficient production of α-pinene in oleaginous yeast that resulted in an α-pinene titer of 19.
