Flavonoids are plant secondary metabolites with great potential in the food industry. Metabolic engineering of is a sustainable production technique. However, the current naringenin production yield is low because of inefficient enzymatic activity. Hence, this study uses gene source screening as a tool to identify the best gene source for enzymes such as 4-coumarate: coenzyme ligase (4CL) and chalcone synthase (CHS). For the first time, the 4CL gene from and the CHS gene from were expressed in and this combination provided the highest yield of naringenin, which was 28-fold higher as compared to the reference strain. The combinations obtained similar performance in the Y-28 strains, where the highest production was 28.68 mg/L. Our results demonstrated that the selection and combination of enzymes from the correct gene source could greatly improve naringenin production. For the future, this could help commercialize flavonoid production, which would result in natural food preservatives and additives.

Erythropoiesis, a remarkably dynamic and efficient process responsible for generating the daily quota of red blood cells (approximately 280 ± 20 billion cells per day), is crucial for maintaining individual health. Any disruption in this pathway can have significant consequences, leading to health issues. According to the World Health Organization, an estimated 25% of the global population presents symptoms of anemia.

We present a laboratory module that uses isolation of antibiotic-resistant bacteria from locally collected stream water samples to introduce undergraduate students to basic microbiological culture-based and molecular techniques. This module also educates them on the global public health threat of antibiotic-resistant organisms. Through eight laboratory sessions, students are involved in quality testing of water sources from their neighborhoods, followed by isolation of extended-spectrum beta-lactamase-producing .

Mycofactocin is a redox cofactor essential for the alcohol metabolism of mycobacteria. While the biosynthesis of mycofactocin is well established, the gene , which encodes an oxidoreductase of the glucose-methanol-choline superfamily, remained functionally uncharacterized. Here, we show that MftG enzymes are almost exclusively found in genomes containing mycofactocin biosynthetic genes and are present in 75% of organisms harboring these genes.

The nature of biological research is changing, driven by the emergence of big data, and new computational models to parse out the information therein. Traditional methods remain the core of biological research but are increasingly either augmented or sometimes replaced by emerging data science tools. This presents a profound opportunity for those circadian researchers interested in incorporating big data and related analyses into their plans.
