More recent studies have documented the occurrence of a specific U VB-absorbing compound with an absorption maximum at 294 nm in the green macroalga Ulva pertusa (Han and Han 2005). UVB-radiation strongly induced this compound and its accumulation resulted in a higher photosynthetic performance under U V exposure,... 

Protoplast fusion has also been successfiilly used to produce novel mold isoprenoids, such as citreoanthrasteroids and citreohybridones (Nakada 2000). Long chain aldehydes, valuable as a bio-flavor, have also been secured along similar procedures fiom tMli cultures of the green seaweed Ulva pertusa, regenerated fiom protoplasts (Fujimura 1990).

Katayama reported volatiles of some air-dried green marine algae at the early stages of gas chromatography (GC) development (3). In recent years, we have explored volatile compounds in fifty or more species of wet and undecomposed seaweeds in Japan green seaweeds Ulva pertusa. Monostroma nitidum, and Enteromorpha clathrata brown seaweeds Laminaria japonica and Undaria pinnatifida, and red seaweeds Porphyra tenera and Porphyra yezoensis by GC and GC-mass spectrometry (MS).

Compounds having greater than 1 odor unit value are assumed to contribute to the chararacteristic aroma in the food. Compounds having less than 1 odor unit value are assumed not to contribute to the characteristic aroma or are less important. Guadagni et al. and Tamura et al. applied this method to the volatiles in apple essence (S) and in Ulva pertusa (10), respectively.

The effect of various algae such as Undaria pinnatifida, S. horneri, Eisenia hicyclis, Cryptonemia scmitziana, Gelidium amasii, and Ulva pertusa Kjellman on bone calcification in the femoral-metaphyseal tissues of rats have been studied. As a result, bone calcium content was significantly increased (Yamaguchi et al., 2001). 

Volatile compounds of Laminaria japonica, Kjellmania crassifolia, Gracilaria verrucosa and Ulva pertusa showed antimicrobial activities [117]. 

Aroma profiles of fresh Ulva pertusa were examined and it was found that 7-heptadecene, hexanal, ( )-2-octenal, ( )-2-nonenal, (Z, )-2,6-nonadienal, ( , )-2,4-decadienal, (Z,Z)-8,ll-heptadecadienal, (Z,Z,Z)-8,11,14-... 

Volatile fractions obtained from Ulva pertusa were tested for anthelmintic activity using santonine solution as the control. Dimethylsulfide fraction was the most powerful against the earthworms which were killed at 1,000, 2,000, and 4,000 times dilutions as compared to santonine, terpene, and carbonyl fractions [118]. The effects of volatile constituents of marine algae Ulva pertusa, Enteromorpha, Codium, and Sargassum) on muscle contraction of earthworms were also investigated. Middle... 

Volatile oil of Ulva pertusa showed feeding attractants activity [120].
