Derivatives Of

In the present work, four derivatives of salicylaldehyde (salicylaldehyde-hydrazone, phenylhydrazone, semicarbazone and thiosemicarbazone) were synthesized using both conventional (95% ethanol) and green (crude glycerol from biodiesel production) solvents. The obtained compounds were identified by elemental microanalysis, as well as FTIR, UV/Vis and 1H-NMR spectroscopic methods. Yields of 93?98% of the compounds in crude glycerol were achieved within 10?25 min. The derivatives of salicylaldehyde and crude glycerol were used as a nitrogen and carbon source, respectively, in the medium for antibiotic (hexaene H-85 and azalomycine B) production by Streptomyces hygroscopicus CH-7. The highest concentrations of hexaene H-85 and azalomycine B were achieved in the medium containing salicylaldehyde-thiosemicarbazone (198 and 69 ?g/cm3, respectively). Derivatives of salicylaldehyde also impacted the strain morphology. In the media with salicylaldehyde- phenylhydrazone and salicylaldehyde-thiosemicarbazone, S. hygroscopicus CH-7 grew like large dispersive pellets with long twisted filaments that produced the highest yield of the antibiotics.

Recirculation System

Duckweed was used to treat effluent from a shrimp farm in a batch wise and recirculation system. The result showed that duckweed could efficiently remove nutrients in the effluent, especially ammonia, which seemed to be the preferred nitrogen source of the plant. Red tilapia was used in the recirculation system and showed high potential in removal of uneaten shrimp feed.

To access better removal of nutrients with algae-based techniques, a dominant alga from real municipal wastewater was identified and its capacity in removing low concentrations of nitrogen (NH+4 or NO−3) and phosphorus (PO3−4) was evaluated. Results showed that Oedogonium brevicingulatum, a filamentous green alga, was confirmed as the dominant alga in the secondary effluent of a municipal wastewater treatment plant by polymerase chain reaction-denaturing gradient gel electrophoresis. Low concentrations of NH+4 or NO−3 (≤5 mg N L−1) and PO3−4 (≤0.5 mg P L−1) were 100% removed by the algae in a 7-d test. The maximum nutrient removal rate (Vmax) and the half-saturation constant (Km) for NH+4 (10.03 ± 0.95 mg g−1d−1 and 0.19 ± 0.03 mg L−1) and NO−3 (8.43 ± 0.21 mg g−1 d−1 and 0.27 ± 0.11 mg L−1) indicated the uptake capability for NH+4 is higher than that for NO−3. Meanwhile, it showed higher affinity for PO3−4 (Vmax: 1.42 ± 0.02 mg g−1 d−1; Km: 0.02 ± 0.00 mg L−1) with NH+4 as nitrogen source than that (Vmax: 1.24 ± 0.15 mg g−1 d−1; Km: 0.06 ± 0.03 mg L−1) with NO−3 as nitrogen source. Moreover, nutrient removal efficiencies were observed steady when nitrogen/phosphorus ratio ranged from 5:1 to 20:1. These results suggest that the dominant algae from municipal wastewater have potentials to be applied in nutrient removal.
