## Abstract **BACKGROUND:** The performance of a three‐stage process for polyhydroxyalkanoate (PHA) bioproduction from olive oil mill effluents (OME) has been investigated. In the first anaerobic stage OME were fermented in a packed bed biofilm reactor into volatile fatty acids (VFAs). This VFA‐ric

The Production of oil of American Wormse

The Production of oil of American Wormseed, U. S. P., in Illinois**This investigation was undertaken because the supply of wormseed oil has been for several years vcry inadequate to the demand, and this condition has prevented extensive use of the oil in the treatment of domestic animals—a field in which it is much needed. Owing to the low individual value of such animals as hogs, for example, it is not economical to treat them with a drug of such high price as wormseed oil. This paper is a report of the first year’s work in producing this oil at the Experiment Station of the Moorman Mfg. Co., Quincy, Ill. It is planned to continue the work on a much larger scale, covering every phase of the problem. Anyone wishing to produce the oil can obtain the full cooperation of this company on request.
