امروزه فلزات سنگین به یکی از خطرناک ترین مسائل زیست محیطی جهانی تبدیل شده اند. آلودگی فلزات سنگین در اکوسیستم های آبی بر ریزجلبک ها و زوپلانکتون ها تأثیر گذار است، بیومس و فراوانی گونه ها را تغییر داده و روابط درون گونه ای را به سمت غالبیت گونه های کمتر حساس به پیش می برد. در این تحقیق اثر تنش کوتاه مدت غلظت های مختلف فلز سنگین کادمیم بر دو میکرو آلگ سیانوباکتری anabaena sp. و جلبک سبز chlorell...

In this researchsaccharomyces cerevisiae (baker’s yeast) was used as a cheap, readily accessible, selective, efficient, and green bio-catalyst in a chemo selective reduction of carbonyl group to hydroxyl group. In this green procedure three substrates e.g. (3-(3-nitrophenyl)aziridin-2-yl)-1-phenyl-methanone, pyruvate ester, and 2-acetyl-γ-butyrolactone were r...
Com este estudo, objetivaram-se isolar e identificar leveduras presentes na microbiota intestinal de Litopenaeusvannamei cultivados em estuário tropical testar in vitro a capacidade probiótica adsorvente aflatoxina B1(AFB1)por cepas Saccharomyces cerevisiae isoladas. Foram adquiridos 40 camarões da espécie L. vannamei, fizeram-se o isolamento identificação intestinais por sequenciamento molecul...
abstract: this study was aimed at probiotication of tomato and carrot juices using lactobacillus plantarum, lb. fermentum, lb. casei, lysinibacillus sphaericus and saccharomyces boulardii. to enhance the stability, the probiotic cultures were micro-encapsulated using alginate coated chitosan beads. tomato and carrot juice samples were pasteurized for 20 min at 63 °c. lb. fermentum, lb. plantara...
In this paper, comparative molecular studies between authentic Saccharomyces cerevisiae strains, related species, and the strain described as Saccharomyces boulardii were performed. The response of a S. boulardii strain and a S. cerevisiae strain (W303) to different stress conditions was also evaluated. The results obtained in this study show that S. boulardii is genetically very close or nearl...
The effects of agrochemicals pollution on soil nutrients, microbes as well plants cultivated the were studied. Insecticide and herbicide used to impact samples across concentration gradients. Bean maize seeds planted in separate experiments monitor plants. microbial diversity physicochemical characteristics before after determined using standard methods. Chlorophyll contents leaves also plantin...
background and purpose: microorganism-based synthesis of nanostructures has recently been noted as a green method for the sustainable development of nanotechnology. nowadays, there have been numerous studies on the emerging resistant pathogenic bacteria and fungal isolates, the probable inability of bacteria and fungi to develop resistance against silver nanoparticles’ (snps) antibacterial, ant...
this study was conducted to evaluate the effect of prebiotic short saccharomyces cerevisiae yeast cell wall (ycw) on growth , nutrition and survival rates , blood indices of rainbow trout (oncorhynchus mykiss) were studied . 600 pieces of salmon with an average weight of (1 ± 20) g 4 treatments and 3 replications (each replication 50 pieces of fish) groups. treatments 1, 2, 3 and 4, respectivel...
