Gas Chromatography‐Mass Spectrometry‐Based Phytochemical Profiling and Bioactivity‐Guided Fractionation of Psidium guineense Stem Extracts: In Vitro and In Silico Insights Into Antioxidant, Antidiabetic and Antibacterial Potentials

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Psidium guineense (Myrtaceae) is traditionally used for various medicinal purposes, although its stem remains underexplored. This study provides the first integrated phytochemical, pharmacological and computational evaluation of the stem extracts to elucidate their antioxidant, antidiabetic and antibacterial potential.

PECTIC GLYCOSIDASES OF ASPERGILLUS NIGER

The Journal of General and Applied Microbiology, 1954
Separation of GPG free from DPG in the manner of the adsorption of the latter on pulpified filter paper (Tab. 1), described in the previous report, is successfully achieved by fractional adsorption (Tab. 2). There is little difference between the properties of GPG thus obtained and of DPG. The optimum pH for the activity to liberate the reducing groups

Establishment of a Single‐Cell Minimal Medium: A Case Study for Microfluidic Cultivation of Corynebacterium glutamicum

Biotechnology and Bioengineering, Volume 123, Issue 6, Page 1648-1660, June 2026.
Conventional bulk media are often unsuitable for single‐cell cultivation and analysis because they provide excess nutrients or lack essential components. Redesigning the medium allows for controlled, defined growth, enabling the development of a robust minimal medium that supports quantitative and reproducible single‐cell analysis across different ...
