In a new study published in Nature Communications, a team of researchers led by Jay Keasling, CEO of the Department of Energy’s Joint BioEnergy Institute (JBEI), report that brewer’s yeast can be engineered to alter the flavor of beer. In this case, the scientists incorporated recombinant DNA derived from yeast, mint, and basil so the brewer’s yeast would biosynthesize aromatic monoterpene molecules that impart hoppy flavor. The benefits of this are two-fold: bioengineering can lead to flavor palette expansion while increasing the sustainability of the brewing process.
ESOC Hosts Antioch High School Students for Mock Interviews
Antioch High School juniors who are taking part in the Biotech Partners program, are getting ready for their interviews in order to get summer internships. Emery Station Operations Center’s operational staff was on hand this week to help the students practice their job application skills during mock interviews.
Using Nature’s Blueprint for Sustainable Indigo Dyeing Process
Indigo has been prized since antiquity for its vibrancy and deep blue hue and, for more than a century, its unique properties have been leveraged to produce the popular textile blue denim. However, the dyeing process requires chemical steps that are environmentally damaging. A team of researchers in the Molecular Biophysics and Integrated Bioimaging (MBIB) and Biological Systems and Engineering (BSE) Divisions, at JBEI, and UC Berkeley have developed a promising sustainable indigo dyeing process that relies on genetically engineered bacteria, mimicking the natural biochemical protecting group strategy employed by the Japanese indigo plant Polygonum tinctorium.
Area Scientists to Present Talks at 2018 AAAS Annual Meeting
Several Berkeley Lab scientists will present talks at the 72nd annual meeting of the American Association for the Advancement of Science (AAAS), the world’s largest general scientific society, to be held February 15 through 19 in Austin, Texas. Among them are four representing the Biosciences Area: Mary Maxon, Blake Simmons, Trent Northen, and Susannah Tringe.
Crystallization Screen Created by Berkeley Lab Biosciences Scientists Reaches the Market
X-ray crystallography has been the most successful technique used to solve macromolecular structures, contributing several thousand new entries to the Protein Data Bank (PDB) every year. The protein crystal is the critical starting point for X-ray data collection, and consequently, its properties are correlated with the quality of the data and the level of detail that can be extracted for a macromolecular structure. However, proteins require solutions of specific composition to form crystals for structure determination studies. These specifications are usually determined from exposing the protein to several different solutions in a crystallization screen.
A team of researchers in the Molecular Biophysics and Integrated Bioimaging (MBIB) Division led by Paul Adams and Jose Henrique Pereira have developed a new crystal screen, the Berkeley Screen, with 96 conditions proven to be highly effective at producing crystals for structural determination. The Berkeley Screen is now available to the wider crystallography community commercially.
