A comparison of screening methods for antioxidant activity in seaweeds
The inhibition of lipid peroxidation and radical scavenging effects were studied to evaluate the antioxidant activity for extracts of 17 species of seaweed. The antioxidant effect was evaluated byExpand
Antioxidants from carbon dioxide fixing Chlorella sorokiniana
Analysis of the biomass shows that protein, carbohydrate and lipids comprised 68.5, 11.9 and 10.0% of dry matter, respectively, and two fractions with radical scavenging activity were isolated from the aqueous extract of C.sorokiniana H-84. Expand
Changes in eicosapentaenoic acid content of Navicula saprophila, Rhodomonas salina and Nitzschia sp. under mixotrophic conditions
Three species of microalgae able to produce eicosapentaenoic acid(EPA) were collected from brackish and sea water around Japan and Navicula saprophila displayed the greatest productivity of EPA and the EPA content of its biomass was enhanced under mixotrophic conditions in the presence of acetic acid.

The possible role of squalene and its peroxide of the sebum in the occurrence of sunburn and protection from the damage caused by U.V. irradiation.
To clarify the role of squalene peroxide in the occurrence of skin damage from sunburn, the optimum condition of squAlene peroxidation and the effect ofSqualenes peroxide on cutaneous tissue were examined and good correspondence was recognized among the spectrum of natural daylight, U.V. irradiation, and absorption spectrum of Squalene and erythema curve.

Enhanced eicosapentaenoic acid production by Navicula saprophila
Changes in the eicosapentaenoic acid (EPA) content of Navicula saprophila grown photoautotrophically and mixotrophically with the addition of acetate were examined in terms of their growth progress.Expand
Development of a highly sensitive chemiluminescence flow-injection analysis sensor for phosphate-ion detection using maltose phosphorylase
A chemiluminescence flow-injection analysis biosensor has been constructed for phosphate-ion detection. This system is coenzymeless and employs a maltose phosphorylase, mutarotase, andExpand
Highly sensitive chemiluminescence flow-injection detection of the red tide phytoplankton Heterosigma carterae
Abstract Two chemiluminescent flow-injection analysis systems for the detection of the red tide Phytoplankton Heterosigma carterae (formerly known as Heterosigma akashiwo ) have been developed. InExpand
Time-resolved fluorescence receptor assay for benzodiazepines
Abstract A novel non-isotopic receptor binding technique for the detection of benzodiazepines is described. A benzodiazepine labeled with europium chelate was prepared and employed as a labeledExpand
Determination of Damaged Starch and Diastatic Activity in Wheat Flour Using a Flow-Injection Analysis Biosensor Method
ABSTRACT The determination of damaged starch and diastatic activity in flour was studied using a flow-injection analysis (FIA) biosensor system. The system consisted of an oxygen electrode and anExpand
Isolation and characterization of a green alga Neochloris sp. for CO2 fixation
A green alga Neochloris sp. TS4F isolated from a pond at Ueno Park, Tokyo, is tolerant of the concentration of 10% CO 2 bubbling at 35°C. This microalga can fix CO 2 at the rate of 0.027 g L 1 h 1 byExpand
