Estimation and comparison of effective compounds (mineral contents, amino acids compositions, fatty acids distributions, protein, fat and total fiber contents) in two algae species Sirophysalis trinodis and Polycladia myrica collected from Qeshm Island were done. The samples washed up with tap water and then were dried in an oven at 40 ◦C for 3 days. The dried algae samples were pulverized and ...
اثر 3 تیمار غذایی، شامل جلبک chlorella vulgaris در 2 غلظت 106 و 107 سلول در میلی لیتر و یک تیمار از مخمر saccharomyces cerevisiae، بر رشد، پروتئین و پروفیل اسیدهای آمینه کل و آزاد روتیفر brachionus calyciflorus پس از 10 روز تغذیه بررسی شد. نرخ رشد ویژه روتیفر تغذیه شده با جلبک نسبت به مخمر معنی دار بود (05/0 < p), ولی تفاوت معنی داری بین دو غلظت جلبک مشاهده نشد. حداکثر تراکم روتیفر (7/10±1790 ...
Regression analysis of the relationship between the size of interphase and mitotic digestive cells of green hydra, and the numbers and total volume of the symbiotic Chlorella algae they contain showed a partial correlation only, suggesting that numbers of algae per cell are not regulated by limiting them to a specific proportion of the host cell, and that the variation observed in numbers of al...
هدف از این مطالعه بررسی خواص ضداکسیدانی عصاره هیدروالکلی سه گونه جلبکی سبز، قهوه ای و قرمز بود. بالاترین و کمترین مقدار فنل را جلبک laurencia snyderia (69/0±9/113 میلی گرم اسید گالیک در گرم عصاره) و جلبک سبز entromorpha intestinalis (05/6±36/72 میلی گرم اسید گالیک در گرم عصاره) داشت. بیشترین مقادیر فلانوئید کل (95/1±05/41 میلی گرم روتین در گرم عصاره) را جلبک قرمز l. snyderia و با این وجود کمتری...
