General description

Sodium arsenate dibasic heptahydrate (As(V)) is an arsenic compound.

Application

Sodium arsenate dibasic heptahydrate may be used as a reference standard for the quantification of arsenic compounds in rice- and seafood-based samples by ion chromatography-inductively coupled plasma/ mass spectrometry. The samples for analysis were prepared by ultrasonic-assisted enzymatic extraction (UAEE).

Aminoglycoside antibiotics require proton motive force (PMF) for bacterial internalization. In non-respiring populations, PMF drops below the level required for drug influx, limiting the utility of aminoglycosides against strict and facultative anaerobes. We recently demonstrated that rhamnolipids (RLs), biosurfactant molecules
