http://dx.doi.org/10.7508/gjesm.2015.01.001

Abstract
  Widespread use of pharmaceuticals has resulted in mixture concentrations ranging from mg/L in effluent to µg/L concentrations in surface water. In a 2008 study, 13 pharmaceuticals, ranging in amounts from 0.0028 to 0.1757 µg/l, were identified in the Tennessee River, USA and its tributaries. ...  Read More

2. Particle-size fractions-dependent extracellular enzyme activity in sediments and implications for resource allocation in a subtropical mangrove ecosystem

L. Luo; J.-D. Gu

Volume 1, Issue 1 , Winter 2015, Pages 15-26

http://dx.doi.org/10.7508/gjesm.2015.01.002

Abstract
  The distribution of extracellular enzyme activities in particle-size fractions of sediments was investigated in a subtropical mangrove ecosystem. Five enzymes involved in carbon (C), nitrogen (N), and phosphorus (P) cycling were analyzed in the sand, silt, and clay of sediments. Among these fractions, ...  Read More

4. An investigation on role of salinity, pH and DO on heavy metals elimination throughout estuarial mixture

A.R. Karbassi; M. Heidari

Volume 1, Issue 1 , Winter 2015, Pages 41-46

http://dx.doi.org/10.7508/gjesm.2015.01.004

Abstract
  One of the most paramount processes that play a considerable role in reducing the concentration of heavy metals during estuarine mixing is flocculation. Not only does such a process cause a huge percentage of metals to come into the particulate phase, but also it provides ample nutrients for the aquatic ...  Read More

6. Optimizing the production of Polyphosphate from Acinetobacter towneri

J. Aravind; T. Saranya; P. Kanmani

Volume 1, Issue 1 , Winter 2015, Pages 63-70

http://dx.doi.org/10.7508/gjesm.2015.01.006

Abstract
  Inorganic polyphosphates (PolyP) are linear polymers of few to several hundred orthophosphate residues, linked by energy-rich phosphoanhydride bonds. Four isolates had been screened from soil sample. By MALDI-TOF analysis, they were identified as Bacillius cereus, Acinetobacter towneri, B. megaterium ...  Read More

Volume 1, Issue 1 , Winter 2015, Pages 95-97

http://dx.doi.org/10.7508/gjesm.2015.01.008

Abstract
  Very little information exists in regards to the control options available for potato flea beetles, Epitrix spp. This short review covers both chemical and ecological options currently available for control of Epitrix spp. Synthetic pyrethroids are the weapon of choice for the beetles. However, the impetus ...  Read More
