A fluorescent lighting device includes an arc tube, an exhaust tube extending from the arc tube, and an amalgam. A resistive heater is located adjacent to at least one of the arc tube and the exhaust tube. A power supply circuit is operatively coupled with the resistive heater. When the fluorescent lighting device is switched from an OFF state to an ON state, the power supply circuit temporarily energizes the resistive heater, thereby heating the at least one of the arc tube and the exhaust tube while the resistive heater is energized, and automatically de-energizing the resistive heater after said heating.

Amalgam heater for fluorescent lamps

The invention relates to a new method for controlling the level and distribution of alkaloids produced by Claviceps purpurea variant strains capable of producing primarily ergocornine, .alpha.-ergocryptine and .beta.-ergocryptine under saprophytic conditions. According to the invention a compound of the biosynthesis path of isoleucine or a compound which promotes the formation of isoleucine by biochemical control is added to the fermentation broth. In other respects fermentation is performed under conditions known per se. By the method of the invention the ratio of .alpha.- and .beta.-ergocryptine formed in the fermentation broth can be adjusted to the optimum value.
