SourceDepartment of Biology, New Mexico State University, Las Cruces, NM 88003-8001, USA. AbstractAIMS:To identify factors associated with the Staphylococcus aureus pine-oil disinfectant-reduced-susceptibility (PD(RS)) mechanism and to describe one possible PD(RS) model.
METHODS AND RESULTS:Comparative genomic sequencing (CGS) and microarray analysis were utilized to detect mutations and transcriptome alterations that occur in a S. aureus PD(RS) mutant. Mutant analysis, antimicrobial gradient plates, growth studies and 3-hydroxy-3-methylglutaryl coenzyme A synthase assays were then performed to confirm the biological consequences of the 'omics' alterations detected in a PD(RS) mutant. CGS uncovered three mutations in a PD(RS) mutant in a(n): alcohol dehydrogenase (adh), catabolite control protein A (ccpA) and an NADPH-flavin oxidoreductase (frp). These mutations lead to increased growth rates; increased transcription of an NAD-dependent D-lactate dehydrogenase gene (ddh); and increased flux through the mevalonate pathway. PD(RS) mutants demonstrated reduced susceptibility to bacitracin and farnesol, and one PD(RS) mutant displayed upregulation of bacA, a bacitracin-resistance gene. Collectively, this evidence demonstrates altered undecaprenol metabolism in PD(RS) mutants.
CONCLUSIONS:The PD(RS) mechanism proposed results from increased catabolic capabilities and increased flux through the mevalonate pathway as well as altered bactoprenol physiology.
SIGNIFICANCE AND IMPACT OF THE STUDY:A novel mechanism that bacteria utilize to overcome the killing effects of PD formulations is proposed that is unique from the PD(RS) mechanism of the enterobacteraciae.
Pine-Sol contains surfactants and a powerful cleaning agent called pine oil that can break down the cell walls of bacteria, leading to their destruction. The ingredients in Pine-Sol disrupt the bacterial cell membranes, causing them to burst and die.
Pine nut oil is pressed from pine nuts; olive oil is pressed from olives. Pine nut oil is much more expensive than olive oil. Olive oil is used in many foods, from salads and pasta to breads and other baked goods, while pine nut oil is used in a few specialty recipes.
To make pine oil for candles at home, you can start by collecting fresh pine needles. Next, crush the pine needles to release their oils. Then, mix the crushed pine needles with a carrier oil, such as olive oil or coconut oil, and let it sit for a few days to infuse. Finally, strain out the pine needles and use the infused oil in your candle-making process.

An essential oil carries a distinctive scent of the plant from which it was extracted. Rosemary oil stimulates hair growth and is considered a strengthening tonic, while pine oil has stimulating effects on the adrenal cortex.

Pine-Sol originally contained pine oil, though it is now a mixture of everything but.
Yes, pine wood is less dense than oil, so it would float on top of oil due to its buoyancy. Oil is less dense than water, so pine wood would also float on water.
8-10% pine oil, alkyl alcohol ethoxylates, sodium petroleum sulfonate and isopropanol. I'm not sure of the elemental abbreviation of pine oil... Po? I'd just say it's 2LeMOnY 2BtRuE!
