Current status of Colletotrichum capsici strains, causal agents of Brown blotch disease of cowpea in Burkina Faso

Brown blotch disease, caused by Colletotrichum capsici, is an important disease of cowpea with a significant yield losses ranging from 42 to 100% in West Africa. In this study, a specific polymerase chain reaction (PCR) primer set CC1F1/CcapR was used to characterize and to study the phylogenetic relationship of thirty eight strains of Colletotrichum species. This primer set is capable of amplifying only C. capsici from...

In vitro seed germination and seedling development of the orchid Coelogyne stricta (D. Don) Schltr.

Coelogyne stricta (D. Don) Schltr., an orchid of high ornamental and medicinal values, is native to Nepal at 1400 to 2000 m elevations. In vitro seed germination and seedling development was carried out on 0.8% (w/v) agar solidified Murashige and Skoog (MS) medium, supplemented with various combinations of α-naphthalene acetic acid (NAA) and 6-benzylaminopurine (BAP). MS medium supplemented with 1 mg/L BAP and 1...

Adsorption of copper, zinc and lead on biosurfactant produced from cassava wastewater

The remediation of soils contaminated by hydrophobic compounds, especially petroleum derivatives, using surfactants has been fairly studied. The use of these compounds in heavy metal contaminated areas is incipient and their mechanism of action has not been totally elucidated yet. The biosurfactants are compounds with surfactant characteristics produced by living organisms and have several environmental advantages, like...

Investigating the antioxidant properties and rutin content of Sea buckthorn (Hippophae rhamnoides L.) leaves and branches

The present study focused on the antioxidant properties and rutin content of leaves and branches of Hippophae rhamnoides L. (Sea buckthorn) in Turkey. Dried leaves (leaf tea), processed (PB) and unprocessed branches (UB) of Sea buckthorn (SBT) were extracted with ethanol and prepared in forms of aqueous extract (AE). All samples were analyzed for their contents of rutin, total phenolics (TPC), total flavonoids (TFC) and...
