Background: There is emerging recognition of the risks of harmful chemical pesticides, fertilizers and 'nutrients' by cannabis growers. One group of chemicals, Plant Growth Regulators (PGRs), many of which have been banned from food crops for decades, have been found unlisted in a number of fertilizers and supplements marketed at cannabis growers.
Methods: This paper predominately uses data from a 2020-21 convenience web survey of mainly small-scale, recent (last 5yrs) cannabis growers from 18 countries (n = 11,479).
Background: The COVID-19 pandemic and the accompanying measures to mitigate infection affected many areas of society, including the supply and use of cannabis. This paper explored how patterns of behaviour among people who cultivate cannabis were affected by the COVID-19 pandemic and restrictions.
Methods: An anonymous web survey of people who cultivated cannabis was conducted from Aug 2020 to Sep 2021, spanning 18 countries and 11 languages (N = 11,479).
Actinomycetes are a prolific source of bioactive natural compounds many of which are used as antibiotics or other drugs. In this study we investigated the genomic and biochemical diversity of 32 actinobacterial strains that had been deposited at the DSMZ-German Collection of Microorganisms and Cell Cultures decades ago. Genome-based phylogeny and DNA-DNA hybridization supported the assignment of these strains to 26 novel species and two novel subspecies and a reclassification of a species.
