The objective of this study was to evaluate different pretreatment methods prior to oxygen delignification on extractives removal and O-delignification selectivity. Four different pretreatment methods were used including ultrasonic treatment, hot water soaking, soda addition-preheating, and applying a high-shear mechanical pretretament. Acacia mangium and mixed hardwood (MHW) kraft pulps were u...

OBJECTIVE To evaluate the anti-plaque and anti-gingivitis properties of Acacia arabicacontaining toothpaste in an adult population. METHODS Sixty subjects with gingivitis were randomly assigned to a test group (Acacia arabica-containing toothpaste) or control group (regular toothpaste). An analysis of plaque index (PI), gingival index (GI) and bleeding on probing index (BOP%) were carried out...

Sensitivity of Methicillin Resistant Staphylococcus aureus (MRSA) isolates purified from post operative wounds (n=100) from patients in surgical wards of Mayo, SIMS and Jinnah Hospital in Lahore-Pakistan was evaluated for antibiotics and plant extracts. The minimum inhibitory concentrations of ethanol extracts of medicinal plants (Opuntia delinii, Acacia nilotica and Aloe vera) and antibiotics ...

Medicinal plants are frequently used for the treatment of various infectious diseases. The objective of this study was to evaluate the antibacterial activity and mode of action of Acacia nilotica and the antibiogram patterns of foodborne and clinical strains of Escherichia coli and Salmonella. The mechanism of action of acacia extracts against E. coli and Salmonella was elucidated by observing ...

White rot fungi are good lignin degraders and have the potential to be used in industry. In the present work, Phellinus sp., Daedalea sp., Trametes versicolor and Pycnoporus coccineus were selected due to their relatively high ligninolytic enzyme activity, and grown on Acacia mangium wood chips under solid state fermentation. Results obtained showed that manganese peroxidase produced is far mor...

BACKGROUND AND THE PURPOSE OF THE STUDY Extrusion-spheronization is an established technique for the production of pellets for pharmaceutical applications. In this study, the feasibility and influence of the incorporation of acacia, by itself and in combination with tragacanth, on the ability of formulations containing 2 model of drugs (ibuprofen and theophylline) to form spherical pellets by e...

Vermicomposting of the pre-composted leaf litter of acacia (Acacia auriculiformis) was studied in reactors of identical volume but with surface area: height ratios varying from 4 to 250. In separate sets of experiments with these reactors, epigeic earthworm species Eudrilus eugeniae and anecic earthworm species Lampito mauritii were employed at densities of 75 and 150 adult animals per litre of...

N2-fixing, drought tolerant and multipurpose Acacia and Prosopis species are appropriate trees for reforestation of degraded areas in arid and semiarid regions of the tropics and subtropics. Acacia and Prosopis trees form N2-fixing nodules with a wide range of rhizobia, for example African acacias mainly with Sinorhizobium sp. and Mesorhizobium sp., and Australian acacias with Bradyrhizobium sp...

Human population pressures upon land resources have increased the need to assess impacts of land use change on soil quality. In order to assess effects of land use changes on soil quality properties in a tropical forest ecosystem of Bangladesh, soil samples were collected from adjacent well-stocked Shorea robusta natural forest, land reforested with Acacia, grassland and cultivated land. Land u...

In swarming season, honeybee queens emit two kinds of queen piping signals: tooting and quacking. These signals are considered to be important for swarming, honeybees distinguish between the through differences in their temporal structures. this study, we revealed that species, Apis cerana mellifera, had different The A. consisted almost one long syllable, while mellifera was constructed from s...
