In this study 152 bacterial strains were isolated from the contaminated oils in the southwest of Iran. Hemolysis was used as a criterion for the primary isolation of biosurfactant producing-bacteria. Fifty five strains had haemolytic activity , among them tweleve strains were good biosurfactant producers by measuring surface tension and emulsification(More)
Asparagus bojnurdensis is described as a new species from the North-East of Khorasan province. The new species is compared with its closest relative A. verticillatus. It is similar to A. verticillatus in having unequal cladodes, branched stem, cladode with acute apex, cladode straight and scale leaves. A. bojnurdensis is also similar to A. khorasanensis in(More)
