• Selenium (Se) hyperaccumulation has a profound effect on plant–arthropod interactions. Here, we investigated floral Se distribution and speciation in flowers the effects of pollen quality plant–pollinator Floral were compared Stanleya pinnata, an hyperaccumulator, Brassica juncea, comparable nonhyperaccumulator. Pollen germination was measured from plants grown with varying concentrations visitation between high low Se. pinnata preferentially allocated to flowers, as nontoxic...
The organ-specific accumulation, spatial distribution, and chemical speciation of selenium (Se) were previously unknown for any species cactus. We investigated Se in Opuntia ficus-indica using inductively coupled plasma mass spectrometry, microfocused x-ray fluorescence elemental mapping (μXRF), K-edge absorption near-edge structure (XANES) spectroscopy, liquid chromatography-mass spectrometry (LC-MS). μXRF showed concentrated inside small conic, vestigial leaves (cladode tips), the cladode...
On the basis of fact that algae have ability to volatilize substantial quantities selenium (Se), we investigated concept including an algal pretreatment unit into a constructed wetland system for removal Se from river water entering Salton Sea. Of six different strains tested, most effective in terms volatilization and column was Chlorella vulgaris strain (designated Cv). Cv removed 96% (supplied as selenate) microcosm within 72 h, with up 61% being by atmosphere. X-ray absorption...
Environmental contextElevated levels of selenium and arsenic in the environment as a result anthropogenic activities are creating significant concerns for health aquatic ecosystems. How biofilms, or microbial communities, interact with chemically modify species has been examined. The results demonstrate that induce structural changes concurrently undergo extensive biotransformation, most cases to less bioavailable species. AbstractArsenic both elements concern especially when released into...
Selenium (Se) is an element of growing environmental concern, because low aqueous concentrations can lead to biomagnification through the aquatic food web. Biofilms, naturally occurring microbial consortia, play numerous important roles in environment, especially biogeochemical cycling toxic elements systems. The complexity forming multispecies biofilms presents challenges for characterization conventional microscopic techniques require chemical and physical modifications sample. Here,...
Brassica plants accumulate selenium (Se) especially in seeds when grown soils laden with Se. We report a chemical analysis of Se (canola, Indian mustard, and white mustard) their hydraulically pressed seed meals, which are used as supplement livestock animal feeds. Complementary techniques were to measure total concentrations, map the localization Se, quantify different forms. Seeds meals contained an average 1.8 2.0 μg g(-1) DW, respectively. Selenium was primarily located cotyledons roots...
시판되는 발효식초 7종을 대상으로 품질특성을 비교 분석하였다. pH는 감식초가 가장 높았으며, 양조식초, 무화과 식초, 쌀식초, 사과식초, 현미식초, 매실식초 순으로 나타났다. 총산의 경우 매실식초가 6.33~6.57%의 범위를 보여 타 시료에 비해 조금 높은 결과를 보였다. 유리아미노산 함량은 양조식초>무화과식초>감식초>쌀식초>매실식초>사과식초 나타났으며, <TEX>${\gamma}$</TEX>-aminobutyric acid(GABA) 함량이 무화과식초와 감식초에서 높게 분석되었다. 항산화성분인 총 폴리페놀 감식초>무화과식초>양조식초>쌀식초 플라보노이드 함량 역시 그 경향이 함량과 일치하였다. 이상의 결과로 보아 현재 상업적으로 대량 판매를 하지 않는 식초가 식초에 유기산 성분과 GABA 풍부한 기능성 식초를 제조하는데 좋은 대안이 될 것으로 사료된다. The quality characteristics of commercial fermented vinegars made...

Methods Octyl methoxycinnamate UVB filter)...
The Lactococcus lactis NRRL B‐1821 prolidase gene was cloned and overexpressed in Escherichia coli . Under suboptimum growth conditions, recombinant soluble active produced; contrast, inclusion bodies were formed under conditions preferred for cell growth. Recombinant retained more than half its full activity between 30 60 °C, completely inactivated after min at 70 °C. CD analysis confirmed that 67 enzyme weak alkali to acidic showed maximum pH 7.0. Although these characteristics are similar...
An engineered aquatic ecosystem was specifically designed to bioremediate selenium (Se), occurring as oxidized inorganic selenate from hypersalinized agricultural drainage water while producing brine shrimp enriched in organic Se and omega-3 omega-6 fatty acids for use value added nutraceutical food supplements. Selenate successfully bioremediated by microalgal metabolism into (seleno-amino acids) partially removed via gaseous volatile formation. Furthermore, filter-feeding that accumulated...
본 연구는 고흥산과 수입산 석류의 화학적 성분분석 및 생리활성 기능을 분석하여 기능성 물질의 소재 개발과 착즙 후 버려지는 부산물 활용 방안에 기여하고자 하였다. 석류 과즙 중 주요 유기산은 citric acid, malic acid가 확인되었으며 유리당으로는 fructose, glucose가 확인되었다. 폴리페놀 함량은 고흥산 과피에서 149.91 mg/g으로 가장 높았고 낮은 함량을 보인 과즙보다는 약 100배 정도 높게 함유되어 있었다. 부위별 ellagic acid 분석한 결과 14.22 미국산에 비해 두 배 이상 나타났으며, 미국산 모두 과즙이나 씨 보다는 함량이 월등히 나타났다. 추출물은 농도 의존적으로 항산화 활성이 증가하였으며, 과피, 씨, 순으로 높은 활성도를 나타냈다. 추출물의 전립선암 세포증식 억제능을 산지에 관계없이 과즙, 암세포 성장억제능이 나타났으며 특히 과즙과 씨에서는 고흥산이 비해서 더 우수하였으며 과피 추출물에서는 미국산이 우수하였다.
