Here we report a newly isolated bacterial strain BA11 from soil, capable of fermenting glycerol to 1,3 PDO, and has been identified to be a strain of Klebsiella pneumoniae. Strain BA11 was fast growing showing peak 1,3 PDO production in 6 h of cultivation with productivity of 1.2 g/L-h without the addition of Vitamin B12. Based on the optimum glycerol utilization (75%) and 1,3 PDO production (8.3 g/L) and yield (0.56 mol/mol glycerol utilized), the most appropriate glycerol concentration for cultivation was 20 g/L. The strain BA11 could tolerate the pH range of 6 to 8.5 as no inhibitory effects were seen on growth as well as 1,3 PDO production. Strain BA11 was most active and could produce high 1,3 PDO in the incubation temperature range of 25 to 40 oC. The production of 1,3 PDO was maximum (9.3 g/L) under aerobic condition with 95.8% glycerol utilization. Addition of glucose to the glycerol fermentation led to increased cell mass but no improvement in the 1,3 PDO production.}, keywords = {Aerobic fermentation,Anaerobic enrichment,Isolation,Molar yield,pH tolerance,productivity}, url = {https://www.gjesm.net/article_10775.html}, eprint = {https://www.gjesm.net/article_10775_385687a820ed7320591bde5b28131176.pdf} } @article { author = {Karbassi, A.R. and Pazoki, M.}, title = {Environmental qualitative assessment of rivers sediments}, journal = {Global Journal of Environmental Science and Management}, volume = {1}, number = {2}, pages = {109-116}, year = {2015}, publisher = {GJESM Publisher (Professor J.

After the library studies and field studies, six samples of water and sediment were taken from the river in order to evaluate heavy metal pollution in sediments. To determine the geochemical phases of metals in sediment samples the 5-step method was used for chemical separation. For quantitative assessment of the severity of contamination in the sediments, the geochemical indicators such as enriched factor (EF) and the accumulation index (Igeo) were used. Also, the statistical analyses including methods such as correlation analysis cluster analysis the (CA), were conducted.The results of the experiments showed that the organic matter deposited varies with the average of 2.49 and ranges between 1.95% and 3.43%. Samples showed concentrations of metals such as calcium, iron, manganese, copper and nickel at all the sampling points were below the global average, whereas the concentration of copper was slightly higher than the global scale. Enriched factor (EF) was calculated for the elements revealed that heavy metals are classified as non-infected. The Geo-accumulation Index showed that the studied elements were uninfected peers. Based on the results of multivariate statistical analysis it was concluded that metals such as manganese, copper, iron, nickel and zinc are mainly natural and calcium metal is likely to have an organic origin.}, keywords = {Khuzestan Province,pollution,sedimentation,Shavoor River,water}, url = {https://www.gjesm.net/article_10772.html}, eprint = {https://www.gjesm.net/article_10772_a717b3eed48427b43eebbdb842d520a7.pdf} } @article { author = {Younis, U. and Bokhari, T.Z. and Malik, S.A. and Raza Shah, M.H. and Athar, M. and Niaz, S.}, title = {Particulate matter effect on biometric and biochemical attributes of fruiting plants}, journal = {Global Journal of Environmental Science and Management}, volume = {1}, number = {2}, pages = {117-124}, year = {2015}, publisher = {GJESM Publisher (Professor J.
