A new Asiatic lily cultivar “Fantasia” was derived from a cross between “Gran-paradiso” and line “No. 96-13” made in 1997. The cultivar was selected mainly for cut flower. “Gran-paradiso” is a orange red cultivar, while “No. 96-13” is a red-purple colored hybrid line. The selection and the survey for the flower characteristics were conducted from 1998 to 2005 in vinyl tunnels and greenhouses of National Institute of Highland Agriculture. The flowering date of “Fantasia” is July 22. The flower has no fragrance and its medium sized flower is 13.4 cm in width. The orange (O28A) colored petals have no spots. The bulb weight of “Fantasia” is about 68 g and its bulb size is about 18.6 cm in circumference.

A new Asiatic lily cultivar “Dajeong” was derived from a cross between “Prato” and “Positano” made in 1997. The cultivar was selected mainly for cut flower. Both “Prato” and “Positano” are well known for their flower color of orange red and yellow, respectively. The selection and the survey for the flower characteristics were conducted from 1998 to 2005 in vinyl tunnels and greenhouses of National Institute of Highland Agriculture. The flowering date of “Dajeong” is July 23. The flower has no fragrance and its medium sized flower is 12.0 cm in width. The medium orange and yellow (ON25 + YO23B) colored petals have no spot. The bulb weight of “Dajeong” is about 55.4 g and its bulb size is about 16.4 cm in circumference.

“Miso”, A new Asiatic lily cultivar was derived from a cross between “Kinks” and a line “A61” made in 1997. Both “Kinks” and “A61” are yellow flower cultivars, while “A61” is a hybrid line. The cultivar was selected mainly for cut flower. The selection and the survey for the flower characteristics were conducted from 1998 to 2005 in vinyl tunnels and greenhouses of National Institute of Highland Agriculture. The flowering date of “Miso” is July 26. The flower has no fragrance and its medium sized flower is 13.7 cm in width. The yellow (Y9A) petal have no spot. The bulb weight of “Miso” is about 42 g and its bulb size is about 15 cm in circumference.

Optimal biodegradation kinetics models to the initial nonylphenol ethoxylates-30 concentration were investigated and had been fitted by the linear regression. Microorganisms capable of degrading nonylphenol ethoxylates-30 were isolated from sewage near Ulsan plant area by enrichment culture technique. Among them, the strain designated as EL-10K had the highest biodegradability and was identified as Pseudomonas from results of taxonomical studies. The optimal conditions for the biodegradation were 1.0 g/l of nonylphenol ethoxylates-30 and 0.02 g/l of ammonium nitrate at pH 7.0 and 30℃. The highest degradation rate of nonylphenol ethoxylates-30 was about 89% for 30 hours incubation on the optimal condition. Biodegradation date were fit by linear regression to equations for 3 kinetic models. The kinetics of biodegradation of nonylphenol ethoxylates was best described by first order model for 0.1 ㎍/l nonylphenol ethoxylates-30 ; by Monod no growth model and Monod with growth model for 0.5 ㎍/ml and 1.0, 5.0 ㎍/ml, respectively.
