Sediment, which is central as a sink for organic material and nutrient cycling, provides habitat for feeding, resting, and nesting of sea cucumbers in aquaculture systems. We conducted a 2 mo experiment to investigate the optimal sea mud to sand ratios in sediment for sea cucumber Apostichopus japonicus (Selenka, 1867) aquaculture. Sea mud (<0.08 mm) and sand (0.08−0.5 mm) were used to prepare ...

This study was designed to explore the relationship between deterioration of sea cucumbers and intestinal flora’s diversity change during preservation using 16S rRNA gene sequencing. We show that body wall cucumber develops white spots on day 4, epidermis dissolves 7. The distinctive OTUs remain relatively low four days storage but increase potential gut microbiota biomarkers are Psychrobacter-...

In this study, we sequenced the genomes of two Shewanella spp., newly isolated from the gut of the sea cucumber Apostichopus japonicus (Selenka, 1867). The whole-genome sequences reported here will expand the repertoire of genomic information for the members of the genus Shewanella and will provide important insights into their roles within microbial communities.

(1) Background: Cucumbers are highly sensitive to drought and UV-B radiation, which may also act synergistically. Silicon is a beneficial element for plants, as it can alleviate negative effects of different environmental constraints. Studies revealed that fertilisation cucumbers with silicon showed variety positive effects, increased plant vitality. The aim this study was investigate the role ...

Human urine obtained from separating toilets was tested as a fertiliser for cultivation of outdoor cucumber (Cucumis sativus L.) in a Nordic climate. The urine used contained high amounts of nitrogen with some phosphorus and potassium, but numbers of enteric microorganisms were low even though urine had not been preserved before sampling. The cucumber yield after urine fertilisation was similar...
