The current study was conducted on the investigation of environmental conditions in the local stores and their impact on contamination of aflatoxin B<sub>1</sub>. Three models of economic crops: maize, wheat, and rice samples were collected from Baghdad and Wasit silos for six consecutive months. Sixty samples of the three grain crops were collected from the stores, (12) samples of cornand (24) samples each of wheat and rice, all samples with three replicates planted on the (PDA) medium. Then, Agricultural and ELISA tests were done. The results showed that the concentration of aflatoxin B<sub>1</sub> by ELISA technique in corn crop was more affected by the pollution compared with other crops. The concentration of aflatoxin B<sub>1 </sub>in cornmeasured 46.2ppb, while rice crops scored less concentration of toxin reached to1.8 ppb.https://eajbsh.journals.ekb.eg/article_16821_2d136eeca59ee19cdfed839aea806506.pdfEgyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences, H.

C. gariepinus </em>of the initial weight of 6.96 ± 0.01g was evaluated over a 56 days period. Five experimental diets were formulated at 0 mg/g (control), 10 mg/g, 20mg/g, 30 mg and 40 mg/g inclusion levels of <em>O. gratissimum</em>. The leaf of <em>O. gratissimum </em>was treated by soaking in water for 72 hours and sun-dried. All diets were isonitrogenous with each treatment having two replicates. Fish fed the 40 mg/g <em>O. gratissimum </em>leaf meal also recorded the best growth performance in body weight gain and specific growth rate (SGR). Statistically, there was significantly increased growth and nutritional performance of fish in this study with increasing inclusion levels of <em>O. gratissimum</em> (P<0.05). There was no adverse effect of <em>O. gratissimum </em>supplementation on the histometric index of fish in this study (P>0.05). There was also significant increase in the gustation of fish with increasing <em>O. gratissimum </em>supplementation (P<0.05). Therefore, the present study suggests that <em>O. gratisimum</em> leaf meal may be supplemented up to 40mg/g level to increase gustation and growth performance of <em>C. gariepinus</em>.https://eajbsh.journals.ekb.eg/article_16822_df5e93b486d69e6e97be79c70288405d.pdfEgyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences, H.

Differences in the composition of the surfaces of the style and the trichomes of the samples under study could be classified into three types of style and seven types of trichomes, which can be reliably used in the classification of genus, and these differences have been made into a key to classification based on the results obtained.https://eajbsh.journals.ekb.eg/article_16823_8bee35479b59b1cf9ff67c449d710e26.pdfEgyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences, H.

M.El-ZabalawyEnvironment and Bio-Agriculture Department, Faculty of Agriculture, Al-Azhar Univrsity, Nasr City, Cairo, EgyptEman T.El-KenanyBotany and Microbiology Department, Faculty of Science, Alexandria University, Alexandria, EgyptJournal Article20181017The discharge of chromium (VI) into aquatic ecosystems has become a matter of concern in all the tannery areas over the last few decades.In this study, biomass of <em>Padina pavonia</em> (Linnaeus) Gaillon, <em>Sargassum hornschuchii </em>C. Agardh, <em>Cystoseira sp.</em> C. Agardh<em>, </em><em>Ulva lactuca </em>L. and <em>Gelidium crinale </em>(Turner) Gaillon were tested for bioremediation of chromium (VI). The results clarified that the amount of metal removed by algae from solution is obviously affected by biomass concentration and the metal removal increased with increasing the biomass of the tested algae. It is also observed that there is consistent increase in the chromium (VI) removal by all tested algae with time in approximately all used concentrations, especially from 4 to 8 hours. Meanwhile, the relative metal removal percentages decreased by increasing the initial metal concentrations and higher removal for metal was observed at lower concentrations. Accordingly, a bioremediation process based on algae biomass is sustainable keeping in account the cost effectiveness and associated environmental benefits.https://eajbsh.journals.ekb.eg/article_16824_09464a635b457c4205b2d1e8074e84a8.pdf
