Vinyl chloride (VC) and 1,4-dioxane (DX) are carcinogens and co-occurring groundwater pollutants. Co-contaminants often affect the ability of microorganisms to biodegrade individual constituents. One of the mechanisms by which microbial cells overcome toxic inhibition is by transforming the inhibitory compounds. In this study, while VC inhibited DX biodegradation, it was surprisingly utilized as a growth substrate by Pseudonocardia dioxanivorans CB1190. Increasing concentrations of VC decreased DX biodegradation rates, whereas increasing DX did not have a strong effect on VC biodegradation.
Non-ribosomal peptides (NRPs) and polyketides (PKs) are among the most profuse families of secondary metabolites (SM) produced by bacteria. These compounds are believed to play an important ecological role in microbe-microbe and microbe-plant interactions in soil and roots microbiomes. Over the years, screening of NRPs and PKs in soil bacteria has resulted in high rates of rediscovery, mainly due to challenges associated with bacterial isolation.
In the last decade, the consumption trend of organic food has increased dramatically worldwide. Since only a few pesticides are authorized in organic crops, concentrations are expected to range at zero or ultra-trace levels. In this context, the aim of the present study was to investigate the need for an improvement in the residue controls at very low concentrations (
The concern regarding alternate sources of energy is mounting day-by-day due to the effect of pollution that is damaging the environment. Algae are a diverse group of aquatic organisms have an efficiency and ability in mitigating carbon dioxide emissions and produce oil with a high productivity which has a lot of potential applications in producing biofuel, otherwise known as the third-generation biofuel.
