The effect of arsenate (As 5+ ) on growth and chlorophyll a production in Chlorella vulgaris, its removal by C. vulgaris and the role of glutathione (GSH) and phytochelatins (PCs) were investigated. C. vulgaris was tolerant to As 5+ at up to 200 mg/L and was capable of consistently removing around 70% of the As 5+ present in growth media over a wide range of exposure concentrations. Spectral an...

The aim of the present study was to investigate selenite effects in the unicellular green algae Chlorella vulgaris as a primary producer and the relationship with intracellular bioaccumulation. The effects of selenite were evaluated by measuring the effect of different selenite concentrations on algal growth during a 144 h exposure period. It was found that lower Se concentrations (≤ 75 mg L(-1...

Natural, products were studied to combat reproductive alterations of lead. The current work aimed to disclose the efficacy of Chlorella vulgaris and Zingiber officinale to alleviate lead acetate induced toxicity. Sixty adult male Wistar rats were distributed into four groups. Group 1 was considered control, group 2 received 200 mg/l PbAc water, group 3 received 50 mg/kg/rat of C. vulgaris extra...

two laboratory and greenhouse experiments were carried out to compare and evaluate the nutrition of phaseolus vulgaris l. plant with foliar spray and root media. in laboratory, effect of four treatments; n- nutrition solution; urban solid waste leachate (uswl); vermi-compost extract and control (distilled water) on germination and seeding growth of phaseolus vulgaris l. was examined for 10 days...

Summary Allelopathic effects of different plant allelochemicals have become the focus studies that aim to determine new pesticidal compounds. Plant extracts with chemical compositions can be obtained using methods extraction, whereas dealing allelopathic properties use biotests obtain fast and precise results. Such were undertaken after noticing industrial hemp (Cannabis sativa L.) on surroundi...

Allelopathy is described as the interference to plant growth resulting from chemical interactions among plants and other organisms mediated through release of bioactive secondary metabolites. Since only a few studies have been reported about role seed allelopathy, an experiment was designed evaluate seeds Portulaca oleracea L. crop species common bean (Phaseolus vulgaris L.), onion (Allium cepa...

The aim of this paper is to evaluate the efficiency of nutrients removal by Chlorella vulgaris (C. vulgaris). The study is comprised of five different fractions, having different quantities of C. vulgaris. From the batch reactor operations it was observed that increasing the content of C. vulgaris in the wastewater caused an apparent increase of removal rates in biochemical oxygen demand (BOD),...
