Abstract: Objective: The Antimicrobial activity is the potential to inhibit the growth of microbes such as bacteria and fungi. The present study was carried out to investigate the antimicrobial activity present in the leaves, stem and pods of Prosopis cineraria. Methods: The Agar well diffusion method was used to test the antimicrobial activity of various parts of Prosopis cineraria. Four fungal and four bacterial strains were used as test microbes. Results: The study was revealed that all the three parts of the plant Prosopis cineraria showed the inhibitory zone against the microorganisms. The highest zone of inhibition was showed by P. cineraria pods against P. funiculosum (16±0.92 mm) and by P. cineraria leaves against S. griseus (20±1.10mm). Conclusion: The antimicrobial activity found in the various parts of the plant may be due to the presence of secondary metabolites isolated from the plant such as flavonoids and steroids.

Abstract: The relationship between the high heating values (HHVs) and the elemental contents of some freshwater biomass were studied. The results obtained from the ultimate analysis show that the HHVs of the freshwater biomass is a function of total carbon and hydrogen contents but, a weak function of oxygen, nitrogen and sulphur. Analyses of the experimental results shows that, the HHVs of the biomass tested are not linearly related to their total hydrogen contents but, directly related to their total Carbon contents. HHV’s calculated from theoretical correlations using the elemental contents of C, H, N, S and O compared well with that of the American Standard of Testing Materials (ASTM) results and also in good agreement with the widely reported values in the acceptable range of 17-21 MJ/kg.

Abstract: Polychaetes nereids groups are the most common in shallow marine habitats and abundant in benthic communities. This group was proved to tolerate a high burden of heavy metals within their tissues. The current work assesses the effect of water criteria; sea water temperature, hydrogen ion concentration (pH), dissolved oxygen concentration, turbidity, conductivity and salinity on the uptake and storage of four heavy metals; Mn,, Pb, Cd and Cu in tissues of the marine polychaete worm Nereis succinea collected from two sites at Hurghada, Red sea; the Marine Biological Station (MBS) and the Fishing Port at Sakala (FPS). Bioaccumulation Factors (BAFs) were determined to evaluate the capability of the investigated annelid worm to accumulate heavy metals, so as to be used as sentinel species for monitoring metal pollutants. Population density of the investigated polychaete was determined at both studied sites as related to water criteria. ANOVA statistical analysis has indicated significant higher concentration of Mn, Pb, Cd and Cu in water at FBS than MBS (P<0.01) and high tissue concentration of Mn, Cd, Pb and Cu at individuals collected from FBS (P<0.01). The highest value of annual mean of BAF at Nereis tissues were recorded for Cu (1023.09±816.55), while the lowest BAF was for Pb (162.97±118.03). Polychaete abundance was significantly higher at MBS. Significant effect was found for water criteria on metal bioaccumulation and population density of Nereis. Data were discussed to evaluate the sensitivity of N. succinea to heavy metal pollutants and its possible use as biological monitor for metal contaminants at marine habitats.
