https://www.selleckchem.com/products/YM155.html A novel cost-effective and widely applicable pH indicator was developed using anthocyanins extracted from the purple subtype of Ocimum sanctum L. and common lab filter paper. This pH indicator was successfully tested to monitor the pH of a wide range of buffers, solutions, irrigation water, and soil solution. Upon testing, the indicator displayed specific colors at corresponding pH ranges. Sucrose showed a stabilizing effect for the color of the extracted anthocyanins. Further, molecular analysis indicated that the leaves from the purple subtypes showed higher transcripts abundance for chalcone synthase, chalcone isomerase, anthocyanidin synthase, and dihydroflavonol 4-reductase than that of the green subtype. Similarly, transcription factors HY5 and a bHLH putatively involved in the biosynthesis of anthocyanins showed up-regulation in the purple subtype of O. sanctum.Burkholderia pyrrocinia B1213, a novel microbe isolated from a Baijiu-producing environment, displayed strong cellulolytic activity on agar plates with glucan as the carbon source and had an activity of 674.5 U/mL after culturing with barley. Genome annotation of B. pyrrocinia identificated a single endoglucanase (EG)-encoding gene, designated as BpEG01790. The endoglucanase BpEG01790 shows 98.28% sequence similarity with an endo-β-1,4-glucanase (EC 3.2.1.4) from Burkholderia stabilis belonging to glycoside hydrolase family 8 (GH8). The gene BpEG01790 has an open reading frame of 1218 bp encoding a 406 amino acid (AA) residue protein (43.0 kDa) with a 40-AA signal peptide. BpEG01790 was successfully cloned into pET28a( +) with and without the signal peptide; however, attempts to overexpress this protein in Escherichia coli BL21(DE3) cells using this expression system failed. BpEG01790 was also cloned into the pCold TF vector. Active BpEG01790 was successfully overexpressed with or without the signal peptide using the pCold TF vector expression system and
