Application

D-(+)-Glucose monohydrate is commonly used as an ingredient in many microbial culture media for the growth and identification of bacteria, yeasts, and molds from various pharmaceutical, environmental, and food and beverage samples.

General description

D-(+)-Glucose monohydrate, commonly known as glucose or dextrose, has several microbiological applications. It is used as a carbon source in microbial culture media to promote the growth and propagation of variety of microorganisms. Glucose is a simple sugar and a primary energy source for bacterial cell metabolism. Glucose monohydrate can also be used as a supplement in media to enhance the growth and productivity of microorganisms used in fermentation processes, for example, in the production of antibiotics, organic acids, and enzymes. It plays an important role in diauxic growth, which refers to the phenomenon in which bacterial cells preferentially utilize glucose as a carbon source before switching to other energy sources. In addition, glucose is a common component in numerous selective and differential media formulations used in the identification and characterization of microorganisms.

Circularization for in vitro reporting of cleavage effects by sequencing (CIRCLE-seq) is a sensitive and unbiased method for defining the genome-wide activity (on-target and off-target) of CRISPR-Cas9 nucleases by selective sequencing of nuclease-cleaved genomic DNA (gDNA). Here, we describe a

Macroautophagy/autophagy, a defense mechanism against aberrant stresses, in neurons counteracts aggregate-prone misfolded protein toxicity. Autophagy induction might be beneficial in neurodegenerative diseases (NDs). The natural compound trehalose promotes autophagy via TFEB (transcription factor EB), ameliorating disease phenotype in multiple ND

The Mre11-Rad50-Xrs2 (MRX) complex detects and processes DNA double-strand breaks (DSBs). Its DNA binding and processing activities are regulated by transitions between an ATP-bound state and a post-hydrolysis cutting state that is nucleolytically active. Mre11 endonuclease activity is stimulated by
