ENGINEERED CYANOBACTERIA WITH ENHANCED LIPID PRODUCTION

NºPublicación: US2019071699A1 07/03/2019

Solicitante:
MORGAN STATE UNIV [US]

Resumen de: US2019071699A1

A recombinant strain of F. diplosiphon was made by transforming wild type F. diplosiphon with a pGEM-7Zf (+) plasmid containing sterol desaturase gene (SD) via electroporation. The recombinant strain was designated B481-SD and overexpressed the sterol desaturase gene to result in enhanced lipid production. Selection made on NaCl enabled growth of the transformant to thrive up to 50 g L−1 NaCl. This strain was designated B481-SDH.

NºPublicación: US2019045812A1 14/02/2019

Solicitante:
INDUSTRY UNIV COOPERATION FOUNDATION HANYANG UNIV [KR]

Resumen de: US2019045812A1

The present invention relates to a new alga having an improved ability to produce a pigment, and when a mutant of the present invention is used, a carotenoid-based pigment, specifically, a xanthophyll can be produced by consuming less energy, so that it is possible to efficiently produce the pigment at the industrial level. Further, the pigment can be applied as a raw material for a food, a health functional food and a medicine, which include the pigment. In particular, since a DNA fragment is not likely to be inserted into a target base sequence or a base sequence other than the target, it is expected that the procedure of constructing the mutant is not regulated as a GMO, so that it is expected that the procedure of constructing the mutant can create a big economic effect in terms of an industry which produces lutein and zeaxanthin by using microalgae.

The domestic wastewater treatment process of the present application consists in connecting two or more bioreactors in series, and conveying water through the chamber-segmented central tube of the first bioreactor, the wastewater passing through the mixture of bioadsorbent material contained in the chambers and leaving the central tube and entering the bioreactor through perforations provided in the lower portion of the central tube. Subsequently, the water passes through the space between the central tube and the inner wall of the bioreactor, where the wastewater comes into contact with the microalgae. The water leaves the first reactor through the upper portion and enters the next reactor through the upper portion of the central tube, where the process is repeated.
