Environmental pollutions and biodegradation

African Journal of Food, Agriculture, Nutrition and Development, 2012
Innumerable novel organic compounds were synthesized during the past few decades [1]. Many of these compounds are used today as pesticides. This usage is causing serious pollution of aquatic bodies and consequently the agricultural soil and the ecosystem. There is excessive exploitation of the earth’s petroleum reserves.

Biodegradation of 17 β-estradiol by Serratia marcescens and Stenotrophomonas tumulicola co-culture isolated from a sewage treatment plant in Upper Egypt

Iranian Journal of Microbiology, 2023
Background and Objectives: 17 β- estradiol (E2) is an important pollutant of the aquatic system. It is responsible for sexual disruptions in the majority of aquatic organisms. This study aimed to search for bacteria with high potential degradation of E2

Introduction of Environmentally Degradable Parameters to Evaluate the Biodegradability of Biodegradable Polymers

PLoS ONE, 2012
Environmentally Degradable Parameter ((Ed)K) is of importance in the describing of biodegradability of environmentally biodegradable polymers (BDPs). In this study, a concept (Ed)K was introduced. A test procedure of using the ISO 14852 method and detecting the evolved carbon dioxide as an analytical parameter was developed, and the calculated (Ed)K ...

Biodegradation of indole at high concentration by persolvent fermentation with the thermophilic fungus Sporotrichum thermophile

, 2007
Indole and its derivatives form a class of toxic recalcitrant environmental pollulants. Sporotrichum thermophile was grown in a persolvent fermentation system containing a large amount of indole.

Biodegradability and the estimation of environmental concentration

Ecotoxicology and Environmental Safety, 1979
Abstract In order to assess the environmental acceptability of a chemical we need to estimate both the lowest concentration at which it will cause adverse effects and the highest concentrations which are likely to be present in the environment.

EVALUATION OF BIODEGRADABILITY AND ENVIRONMENTAL IMPACT OF BIOWASTE LEACHATE [PDF]

The holistic approach to environment, 2019
As the world’s population and urbanization have significantly increased in the past few decades, the generation of municipal solid waste has accelerated on global scale. The biowaste disposal, which is an integral part of municipal waste, leads to leachate production.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
