Morpholinium 5-chloro-2-nitrobenzoate

Acta Crystallographica Section E Structure Reports Online, 2001
In the title compound, C4H10NO+·C7H3ClNO4−, two cations and two anions are connected by N—H⋯O hydrogen bonds to afford a ring with descriptor R44(12), which is located on an inversion center. There are four C—H⋯O interactions which connect the ring units to form a three-dimensional network.

Hepatoprotective Properties of Opuntia ficus indica Cladodes Against NiSO4‐Induced Oxidative Stress and Liver Damage

Food Science &Nutrition, Volume 13, Issue 10, October 2025.
Our study suggests that Opuntia ficus indica cladode juice exhibits hepatoprotective properties, mitigating liver damage induced by nickel exposure. The polyphenol content was determined using spectrophotometric analysis and HPLC‐MS. Experimental hepatotoxicity was induced by intraperitoneal (i.p.) injection of NiSO4.

Perfoliate Pondweed Meadows in Northern Coastal Areas—Reservoirs of Diverse Bacteria With Pathogenic Traits and Complex Carbon Metabolism

Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.
The perfoliate pondweed, Potamogeton perfoliatus, is a common macrophyte in freshwater and subarctic coastal areas. This species builds extensive meadows that play a role as a filter removing nutrients traversing from land to sea and maintaining essential ecosystem functions.

Bioavailability of pollutants and chemotaxis [PDF]

, 2013
The exposure of bacteria to pollutants induces frequently chemoattraction or chemorepellent reactions. Recent research suggests that the capacity to degrade a toxic compound has co-evolved in some bacteria with the capacity to chemotactically react to it.

Piperidiniump-nitrobenzoate

Acta Crystallographica Section E Structure Reports Online, 2001
A new type of hydrogen-bond pattern for piperidinium p-substituted benzoates is reported; this is found in piperidinium p-nitro­benzoate, C5H12N+·C7H4NO4−, (I). In the crystal of (I), the cations and anions are linked by N—H⋯O hydrogen bonds around a center of symmetry to form a cyclic dimer of the formula unit.

Transcriptomic Analyses Unveil Hydrocarbon Degradation Mechanisms in a Novel Polar Rhodococcus sp. Strain R1B_2T From a High Arctic Intertidal Zone Exposed to Ultra‐Low Sulphur Fuel Oil

Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.
Cold‐adapted Rhodococcus sp. strain R1B_2T from Arctic Tupirvik Beach (Northwest Passage) degrades short‐ to long‐chain hydrocarbons in summer seawater (−1°C to 5°C) via a synergistic activity of key hydrocarbon degradation genes (alkB, CYP153, almA, and ladA), with rhlABCR‐linked rhamnolipid production supporting biodegradation.

Benzyl 2,6-dihydroxy-3-nitrobenzoate

Acta Crystallographica Section E Structure Reports Online, 2007
Crystals of the title compound, C14H11NO6, were obtained by the reaction of benzyl 2,6-dihydroxy­benzoate with nitric acid and crystallization of the product from ethyl acetate. In the mol­ecule, the nitro group is essentially coplanar with the attached benzene ring [O—N—C—C = 176.75 (11)°], indicating conjugation with the π-electron system.
