BACKGROUND In Europe, Acacia and Eucalyptus, originate large amounts of biomass, due to their need by industries and other biological control, that can be used to extract antimicrobial substances. MATERIALS AND METHODS Foliar aqueous, ethanolic and methanolic extracts of Acacia baileyana (Cootamundra wattle), Acacia dealbata (silver wattle), Acacia melanoxylon (black wattle) and Eucalyptus ni...

The diversification of gall-inducing Australian Kladothrips (Insecta: Thysanoptera) on Acacia has produced a pair of sister-clades, each of which includes a suite of lineages that utilize virtually the same set of 15 closely related host plant species. This pattern of parallel insect-host plant radiation may be driven by cospeciation, host-shifting to the same set of host plants, or some combin...

For a fixed C∗-algebra A, we consider all noncommutative dynamical systems that can be generated by A. More precisely, an Adynamical system is a triple (i, B, α) where α is a ∗-endomorphism of a C∗-algebra B, and i : A ⊆ B is the inclusion of A as a C∗-subalgebra with the property that B is generated by A∪α(A)∪α(A)∪ · · · . There is a natural hierarchy in the class of A-dynamical systems, and t...

background: a bulk of contraceptives on the market is women-oriented today. the aim of this study was to investigate the effect of a medicinal herb, acacia nilotica on various parameters of male fertility using a rat model. methods: male wistar rats (n=40) were randomly divided in to two groups. one group received acacia nilotica, while the other acted as controls. ten animals from each group w...

Dart, P. J. (University of Sydney, Sydney, Australia), and F. V. Mercer. Fine structure of bacteroids in root nodules of Vigna sinensis, Acacia longifolia, Viminaria juncea, and Lupinus angustifolius. J. Bacteriol. 91:1314-1319.-In nodules of Vigna sinensis, Acacia longifolia, and Viminaria juncea, membrane envelopes enclose groups of bacteroids. The bacteroids often contain inclusion granules ...

Abstract This paper succinctly describes and then illustrates the species Paris polyphylla S mith var. nullopetalina J. L. Liu et Y. Yuan, which is a new variety of Trilliaceae found in Sichuan Province Southwestern China. It closely related to Smith panxiensis Liu, stenophylla Franch minora S. F. Wang. The distinguishing features that can be used identify this are as follows: leaf blade narrow...

The leaves of Acacia nilotica (L.) Delile was extracted with methanol and aqueous medium and studied for in vitro antimicrobial property. The methanol extract was found to be most active against all the bacterial species tested except S.aureus. Active methanol extract was further studied for HPTLC fingerprint and by phytochemical analysis. HPTLC analysis confirmed segregation of four individual...

The adsorption technique using chemically treated powder of bark of Acacia arabica was applied for the removal of toxic heavy metals from polluted waste water. The extent of adsorption found to be dependent on the pH and the time of contact. The adsorbent is effective for the quantitative removal of various toxic metals from the contaminated aqueous sample. The method is quite feasible, economi...
