Flavonoid, pterocarpans and steroid from Erythrina fusca Lour. growing in Bangladesh: isolation, antimicrobial free-radical scavenging activity

The lichen Anaptychia fusca and several Stereocaulon species have been chemically investigat­ ed with regard to their content o f unknown ninhydrin-positive compounds. N ew aliphatic and alicyclic, amino components isolated from water extracts o f these lichen species have been charac­ terised as aminopentitol, aminohexitol and aminocyclitetrol. To our knowledge, this is the first time that com...

Carotenoids, Chlorella fusca, Chlorophylls, Iron Stress, Vanadate The pigment composition of Chlorella fusca has been investigated in the absence and in presence of vanadate and during iron stress. 1. Fe-deficiency generally decreases algal pigment content without change of the ratio chloro­ phyll a/b. 2. A twofold vanadate induced increase of the chlorophylls is accompanied by a similar enhanc...

Busseola fusca (Lepidoptera: Noctuidae) is an important pest of maize and sorghum in sub-Saharan Africa. One century after its first description by Fuller in 1901, inaccurate information based on earlier reports are still propagated on its distribution (e.g., absent from the lower altitudes in East Africa) and host plant range (e.g., feeding on a large range of wild grass species). This review ...

the aim of this study was measuring the amount of heavy metals (nickel, cobalt, cadmium, chromium and zinc) in different tissues of black fish (capoeta fusca). for this reason, in july 2010, 24 black fish was caught at the central part qanats of birjand. the results showed that between the whole length and the weight of fish and concentration of heavy metals in different observed tissues there ...

Podosphaera fusca is the main causal agent of cucurbit powdery mildew in Spain. Four Bacillus subtilis strains, UMAF6614, UMAF6619, UMAF6639, and UMAF8561, with proven ability to suppress the disease on melon in detached leaf and seedling assays, were subjected to further analyses to elucidate the mode of action involved in their biocontrol performance. Cell-free supernatants showed antifungal ...

Fungi were isolated from soil samples corresponding to pesticide-contaminated soil (CS) and noncontaminated soil (NCS) in the Annaba vicinity (Algeria) and identified. The number of isolates obtained from CS and NCS were 263 and 288, respectively. The most frequent species (Aspergillus fumigatus, A. niger, A. terreus, Absidia corymbifera, and Rhizopus microsporus var microsporus) were not sensi...

background: this study aims to investigate the patterns of bioaccumulation and depuration of copper in the selected kidney and liver of capoeta fusca. methods: the fish were collected between september and november 2010 from a qanat in birjand. they were exposed to two types treatments with copper (0.25 and 0.75 mg/l) for a period of 41 days. the fish under study were exposed to the above-menti...

ABSTRACT Overwintering of tobacco thrips, Frankliniella fusca, was investigated on common winter annual host plants infected with Tomato spotted wilt virus (TSWV). Populations of tobacco thrips produced on TSWV-infected plants did not differ from those produced on healthy plants, whereas populations varied greatly among host plant species. The mean per plant populations of F. fusca averaged 401...

Thermobifidas are thermotolerant, compost inhabiting actinomycetes which have complex polysaccharide hydrolyzing enzyme systems. The best characterized enzymes of these hydrolases are cellulases from T. fusca, while other important enzymes especially hemicellulases are not deeply explored. To fill this gap we cloned and investigated endomannanases from those reference strains of the Thermobifid...
