The signal of the chemical substances on the marker pen used appears on the channel with an m/z value of 322.1918, 323.1953, 546.4010, and etc, from the single cell deconvolution sampling layer class_4. This test data was tested by chuxiaoping from PANOMIX’s R&D laboratory.

Despite covering less than 0.1% of coastal regions, they have the capacity to bury up to 10% of marine organic matter and can bury the same amount of carbon 35 times faster than tropical rainforests. On land, the soil’s ability to sequestrate carbon is intimately linked to microbial metabolism. Despite the growing attention to the link between plant production, microbial communities, and the carbon cycle in terrestrial ecosystems, these processes remain enigmatic in the sea. Here, we show that seagrasses excrete organic sugars, namely in the form of sucrose, into their rhizospheres. Surprisingly, the microbial communities living underneath meadows do not fully use this sugar stock in their metabolism. Instead, sucrose piles up in the sediments to mM concentrations underneath multiple types of seagrass meadows. Sediment incubation experiments show that microbial communities living underneath a meadow use sucrose at low metabolic rates. Our metagenomic analyses revealed that the distinct community of microorganisms occurring underneath meadows is limited in their ability to degrade simple sugars, which allows these compounds to persist in the environment over relatively long periods of time. Our findings reveal how seagrasses form blue carbon stocks despite the relatively small area they occupy. Unfortunately, anthropogenic disturbances are threatening the long-term persistence of seagrass meadows. Given that these sediments contain a large stock of sugars that heterotopic bacteria can degrade, it is even more important to protect these ecosystems from degradation.

1-Naphthol, or ?-naphthol, is a colorless crystalline solid with the formula C10H7OH. It is an isomer of 2-naphthol differing by the location of the hydroxyl group on naphthalene. The naphthols are naphthalene homologues of phenol, with the hydroxyl group being more reactive than in the phenols. Both isomers are soluble in simple alcohols, ethers, and chloroform. They can be used in the production of dyes and in organic synthesis.; 1-naphthol (1N) is a metabolite of carbaryl and naphthalene that is an intermediate in Metabolism of xenobiotics by cytochrome P450. It is generated by spontaneous reaction from (1R,2S)-Naphthalene epoxide then is it converted to 1,4-Dihydroxynaphthalene. Although 1-Naphthol is not persistent in the body, a single urine sample may adequately predict exposure over several months to chlorpyrifos, which is a broad-spectrum organophosphate insecticide. In adult men, TCPY and 1N were associated with reduced testosterone levels (PMID: 16357596, 15579421). Naphthalen-1-ol is found in black walnut. 1-naphthol (1N) is a metabolite of carbaryl and naphthalene that is an intermediate in Metabolism of xenobiotics by cytochrome P450.
