Anoxic incubation of sediment in gas-tight plastic bags: a method for biogeochemical process studies

Plastic Bags: Hazards and Mitigation

Failure to sterilize in plastic bags.

The ideal container for discarded cultures and other contaminated materials which require autoclaving to render them safe should be reasonably cheap, resistant to corrosion, leak-proof, and capable of allowing the passage of steam to all parts of its contents. Perhaps because of the difficulty of meeting all these requirements with the metal containers which have traditionally been used some la...

Biogeochemical Cycle of Methanol in Anoxic Deep-Sea Sediments

The biological flux and lifetime of methanol in anoxic marine sediments are largely unknown. We herein reported, for the first time, quantitative methanol removal rates in subsurface sediments. Anaerobic incubation experiments with radiotracers showed high rates of microbial methanol consumption. Notably, methanol oxidation to CO2 surpassed methanol assimilation and methanogenesis from CO2/H2 a...

Toward a Thorough Approach to Predicting Klinkenberg Permeability in a Tight Gas Reservoir: A Comparative Study

Klinkenberg permeability is an important parameter in tight gas reservoirs. There are conventional methods for determining it, but these methods depend on core permeability. Cores are few in number, but well logs are usually accessible for all wells and provide continuous information. In this regard, regression methods have been used to achieve reliable relations between log readings and Klinke...

Community’s perception of utilization and disposal of plastic bags in Eastern Ethiopia

Plastics, one of the most abundant materials in the world today, are one of the main sources of pollution. People’s perception of using and disposing plastic bags is primordial as they tend to be a major part of household solid waste. This study aims to determine community’s perception of usage and disposal of plastic bags in Eastern Ethiopia. A quantitative cross-sectional study has been condu...
