Also disclosed herein are process for preparing the cyanobacterial extract and uses of the cyanobacterial extract.
Resumen de: US2025011678A1
The present invention relates to a bio-oil extraction method with an improved oil recovery rate by using a cooling process. The bio-oil extraction method of the present invention, in which a process of cooling a suspension obtained by disrupting cells of a culture solution containing microalgae is further carried out, exhibits a high oil recovery rate, and does not comprise adding other additives to increase an oil recovery rate, thus enabling oil recovery and the use of remaining by-products as feed, whereby sustainable production is possible, and the recovered oil can be effectively used as a feed composition, a food composition, or the like.

The present disclosure provides a modified promoter capable of flexibly adjusting the expression level of a gene encoding a protein. The disclosed modified promoter is a base sequence (SEQ ID NO: 1) of a 348 base upstream of an initiation codon of an slr1841 gene, or a base sequence having 80% or more homology with the base sequence represented by SEQ ID NO: 1. And a promoter modified by at least one method selected from the group consisting of (i) substitution of one or more bases contained in the base sequence with another base, (ii) deletion of one or more bases from the base sequence, and (iii) insertion of one or more bases into the base sequence.
Resumen de: CN119265268A
The invention discloses a method for promoting microalgae to treat ethanol wastewater to recover lipids by adding acetic acid bacteria, relates to the field of recovering lipids by using microalgae, and particularly relates to a method for simultaneously removing ethanol and recovering lipids by using ethanol wastewater as a substrate and adding acetic acid bacteria (acetobacter pasteurianus CICC 20056) and chlorella (chlorella sorojin chlorella FACHB-24) to construct a bacteria-algae symbiotic system. In the system, the acetobacter pasteurianus metabolizes ethanol in the wastewater into acetic acid by using oxygen generated by photosynthesis of the microalgae, the microalgae store the acetic acid as a substrate into lipid, and the acetic acid and the lipid form a mutualistic symbiotic relationship, so that the ethanol in the ethanol-containing wastewater is efficiently removed, and the lipid accumulation efficiency of the microalgae is remarkably improved.
