Research ArticleOpen accessAll words, across the recordPlant Growth Promoting Activity of Actinomycetes Isolated from Soybean RhizosphereAris Tri Wahyudi, Jepri Agung Priyanto, Resti Afrista et al.Plant Growth Promoting Rhizobacteria (PGPR) is considered as the biological agent for improving plant growth. One Group of PGPR that have an important role in growth promoting of plant is Actinomycetes. The objective of this study was to isolate and screen Actinomycetes isolated from soybean rhizosphere as growth promoter of soybean in vitro. Fifty-three Actinomycetes isolates have successfully been isolated … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 5 Jan 2019 · 14,604 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordRemediation of Methyl Tert-Butyl Ether (MTBE) Contaminated Water by Using In situ Catalytic and Biological Combined TechniquesA. Nikpay, H. Kazemian, M. SadeghiThe hydrolysis reaction of Methyl Tert-Butyl Ether (MTBE) into biodegradable products was studied on as-synthesized and commercial H-MFI zeolites. The effect of synthesis procedure and SiO2/Al2O3 ratio was investigated. The results obtained were indicated that H-MFI zeolites were effective in MTBE hydrolysis and increasing of the Si/Al ratio promotes the hydrolysis reaction. The amount of produced TBA was always lower … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,634 accessesView PDFCite
