Cytokinins enhance the metabolic activity of in vitro-grown catmint (Nepeta nuda L.).

The phytohormones cytokinins are essential mediators of developmental and environmental signaling, primarily during cell division and endophytic interactions, among other processes. Considering the limited understanding of the regulatory mechanisms that affect the growth and bioactivity of the medicinal plant Nepeta nuda (Lamiaceae), our study aimed to explore how cytokinins influence the plant's metabolic status. Exogenous administration of active cytokinin forms on in vitro N.

Jewel Orchid's Biology and Physiological Response to Aquaponic Water as a Potential Fertilizer.

is commonly known as a jewel orchid due to its variegated leaves. Easy maintenance of the orchid allows it to be used as a test system for various fertilizers and nutrient sources, including aquaponic water (AW). First, we applied DNA barcoding to assess the taxonomic identity of this terrestrial orchid and to construct phylogenetic trees.

Electrofiltration improves dead-end filtration of hyaluronic acid and presents an alternative downstream processing step that overcomes technological challenges of conventional methods.

Hyaluronic acid (HA) dispersion obtained from the bacteria was concentrated by electrofiltration. In the conventional downstream processing of HA, extraction and precipitation lead to increase in environmental issues, structural changes, and time and energy related costs. Using electrofiltration as an alternative technology delivers solutions to these limitations.

Accumulation of CdS nanoparticles by yeasts in a fed-batch bioprocess.

The yeasts Schizosaccharomyces pombe and Candida glabrata were successfully cultivated in a fed-batch process at cadmium levels up to 100 mg l(-1). S. pombe incorporated 20 mg C dg(-1) dry biomass within 24h.
