Extinction Coefficients of Chlorophyll a and b in N,N .

We found inconsistencies in the commonly used data for chlorophyll analysis in 80% acetone. Recently developed extinction coefficients for chlorophyll b in N,N -dimethylformamide (DMF) based on values from 80% acetone are low as a result of these inconsistencies. We determined extinction coefficients of chlorophyll a (Chl a ) and chlorophyll b (Chl b ) in DMF for wavelengths of 618 to 665 .

Molecular Mechanism of N,N-Dimethylformamide Degradation .

N, N -Dimethylformamide (DMF) is one of the most common xenobiotic chemicals, and it can be easily emitted into the environment, where it causes harm to human beings. Herein, an efficient DMF-degrading strain, DM1, was isolated and identified as Methylobacterium sp. This strain can use DMF as the sole source of carbon and nitrogen. Whole-genome sequencing of strain DM1 revealed that it has a .

This paper reports and discusses the beneficial effects on the quality of electrospun polycaprolactone nanofibers brought about by pretreatment of the solvent with non-thermal plasma. Chloroform/dimethylformamide 9:1 (CHCl3:DMF 9:1) and pure chloroform were pretreated by a few minute exposure to the plasma generated by an atmospheric pressure plasma jet (APPJ).

Evolution experiments were performed with LB agar plates to which dimethylformamide (DMF) at 50, 60, 70, 80, and 90 g/liter and kanamycin at 25 μg/ml had been added. The size of every evolving population was limited to 10 6 cells. Colonies were counted after 3 days of growth, and 10 colonies were selected for the next plating.

For one, you may not have that level of vacuum control to work with, or you might be relying on facility water for your coolant. Using the rule of 20 on an adjustable temperature scale works too. For example, if your vapor temperature is 30°C, you can set your bath 20°C higher at 50°C and your coolant 20°C lower at 10.

The rotovap had a hot bath set at 75 °C, speed fixed at 80 revolutions per minute, cooling coil running with ice water, and was placed under vacuum until about 150 mL of the liquid (predominantly water) was collected in the trap. The process of adding 150 mL of DMF and removing 150 mL of liquid via the rotovap was repeated several times.
