Isolation and screening of polyhydroxyalkanoates producing bacteria from pulp, paper, and cardboard industry wastes.

International journal of biomaterials

Bhuwal AK, Singh G, Aggarwal NK, Goyal V, Yadav A.
PMID: 24288534
Int J Biomater. 2013;2013:752821. doi: 10.1155/2013/752821. Epub 2013 Oct 29.

Background. Polyhydroxyalkanoates (PHAs) are storage materials that accumulate by various bacteria as energy and carbon reserve materials. They are biodegradable, environmentally friendly, and also biocompatible bioplastics. Unlike petrochemical-based plastics that take several decades to fully degrade, PHAs can be...

A tripeptide-based self-shrinking hydrogel for waste-water treatment: removal of toxic organic dyes and lead (Pb.

Chemical communications (Cambridge, England)

Basak S, Nandi N, Paul S, Hamley IW, Banerjee A.
PMID: 28513651
Chem Commun (Camb). 2017 May 30;53(43):5910-5913. doi: 10.1039/c7cc01774j.

A triphenylalanine-based superhydrogel shows automatic syneresis (self-compressing properties) with time and this self-shrinking behavior has been successfully utilized to remove toxic lead ions and organic dyes from waste-water efficiently with the ability to re-use for a few times.

Biomethanation of Syngas Using Anaerobic Sludge: Shift in the Catabolic Routes with the CO Partial Pressure Increase.

Frontiers in microbiology

Sancho Navarro S, Cimpoia R, Bruant G, Guiot SR.
PMID: 27536280
Front Microbiol. 2016 Aug 03;7:1188. doi: 10.3389/fmicb.2016.01188. eCollection 2016.

Syngas generated by thermal gasification of biomass or coal can be steam reformed and purified into methane, which could be used locally for energy needs, or re-injected in the natural gas grid. As an alternative to chemical catalysis, the...

Development and testing of an in-stream phosphorus cycling model for the soil and water assessment tool.

Journal of environmental quality

White MJ, Storm DE, Mittelstet A, Busteed PR, Haggard BE, Rossi C.
PMID: 25602554
J Environ Qual. 2014 Jan;43(1):215-23. doi: 10.2134/jeq2011.0348.

The Soil and Water Assessment Tool is widely used to predict the fate and transport of phosphorus (P) from the landscape through streams and rivers. The current in-stream P submodel may not be suitable for many stream systems, particularly...

Heavy metals in vegetables: screening health risks involved in cultivation along wastewater drain and irrigating with wastewater.

Sharma A, Katnoria JK, Nagpal AK.
PMID: 27218003
Springerplus. 2016 Apr 19;5:488. doi: 10.1186/s40064-016-2129-1. eCollection 2016.

Irrigation of agricultural land with wastewater leads to continuous buildup of metals at these sites which gets accumulated in the vegetables and crops growing on these sites. Not just the crops irrigated with wastewater are hazardous, in present study,...

Metatranscriptomic and metagenomic description of the bacterial nitrogen metabolism in waste water wet oxidation effluents.

Heliyon

Crovadore J, Soljan V, Calmin G, Chablais R, Cochard B, Lefort F.
PMID: 29062974
Heliyon. 2017 Oct 18;3(10):e00427. doi: 10.1016/j.heliyon.2017.e00427. eCollection 2017 Oct.

Anaerobic digestion is a common method for reducing the amount of sludge solids in used waters and enabling biogas production. The wet oxidation process (WOX) improves anaerobic digestion by converting carbon into methane through oxidation of organic compounds. WOX...

Dispersive solid phase microextraction with magnetic graphene oxide as the sorbent for separation and preconcentration of ultra-trace amounts of gold ions.

Talanta

Kazemi E, Dadfarnia S, Haji Shabani AM.
