Paraffin oxidation in Pseudomonas aeruginosa. I. Induction of paraffin oxidation.

The induction of paraffin oxidation in intact cells of Pseudomonas aeruginosa was investigated. Oxidation of (14)C-heptane by cell-free extracts of adapted cells showed that the activity of whole cells is a reliable reflection of the synthesis of the first enzyme in the degradation of n-alkanes. Induction was significantly affected by glucose and could be completely repressed by malate. The ami...

Preventing Paraffin-Related Injury

Paraffin (called kerosene in North America and other parts of the world) is the most commonly used fuel in ‎non-electrified dwellings worldwide. It is especially popular in Africa and South Asia. Although paraffin ‎offers many advantages-especially its comparatively low cost to produce-it poses two major risks of ‎injury. First, paraffin poisoning is common, either through ingestion or through ...

Comparison of Paraffin Bait, Humic Acid Vitamin B Agar and Paraffin Agar Methods to Isolate Nocardia from Soil

Abstract Background and Objective: The Isolation of Nocardia species is complex and time-consuming, which is due to rapid growth of adjacent bacteria. Because of the importance of a specific medium with the ability of controlling intrusive microorganisms, this study aimed at comparing three laboratory methods to introduce the reliable isolation technique for Nocardia species. Material and Met...

Paraffin Actuated Surface Micromachined Valves

A new, active, normally-open blocking microvalve that uses the thermal expansion of a sealed, thin paraffin patch for actuation has been fabricated and tested. The entire structure is batch-fabricated by surface micromachining the actuator and channel materials on top of a single substrate. The paraffin actuated microvalves are suitable for applications requiring many devices on a single die, l...
