Can the biological stage of a mechanical-biological treatment plant that is designed for mixed municipal solid waste be successfully utilized for effective composting of selectively collected biowaste?

Waste Manag 2022 Jun 24;149:291-301. Epub 2022 Jun 24.

Regional Municipal Waste Treatment Plant in Elbląg, Poland.

Although the requirements for overall recycling rates can only be met when organic recycling is not overlooked, information is scarce regarding adaption to biowaste composting of existing mechanical-biological treatment (MBT) plants originally designed for stabilization of organic municipal solid waste (OFMSW). Thus, this study aimed to assess the suitability of the operational conditions in the biological part of a full-scale MBT plant now used for stabilization of OFMSW (working line: closed-module-covered-pile-open-pile) with a view to producing compost from biowaste. Temperatures above 75 °C were maintained in the closed module and reached again in the covered pile, indicating that intensive organic-matter mineralization occurred in both stages. Read More

Assessing multiple fecal sources to surf zone waters of two recreational beaches by bacterial community analysis.

Water Res 2022 Jun 19;221:118781. Epub 2022 Jun 19.

Bren School of Environmental Science & Management, University of California, Santa Barbara, USA. Electronic address:

Fecal sources to recreational surf zone waters should be identified to protect public health. While watershed origins of human and other fecal sources are often discoverable by quantitative polymerase chain reaction (qPCR) of fecal markers using spatially stratified samples, similarly assessing wastewater treatment plant (WWTP) outfall and other offshore contributions to surf zones is challenged by individual marker fate and transport. Here, bacterial communities were assessed for relatedness between all hypothesized fecal sources and surf zone waters for two urban California recreational beaches, by sequencing genes encoding 16S rRNA and analyzing data using SourceTracker and FEAST.

Topoisomerase VI participates in an insulator-like function that prevents H3K9me2 spreading.

Proc Natl Acad Sci U S A 2022 Jul 27;119(27):e2001290119. Epub 2022 Jun 27.

BIAM, UMR 7265, Aix Marseille Univ, CEA, CNRS, Marseille, F-13009 France.

The organization of the genome into transcriptionally active and inactive chromatin domains requires well-delineated chromatin boundaries and insulator functions in order to maintain the identity of adjacent genomic loci with antagonistic chromatin marks and functionality. In plants that lack known chromatin insulators, the mechanisms that prevent heterochromatin spreading into euchromatin remain to be identified. Here, we show that DNA Topoisomerase VI participates in a chromatin boundary function that safeguards the expression of genes in euchromatin islands within silenced heterochromatin regions.
