We present a method to visualize cuticle in live C. elegans using the red fluorescent lipophilic dye DiI (1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate), which is commonly used in C. elegans to visualize environmentally exposed neurons. With this optimized protocol, alae and annular cuticular structures are stained by DiI and observed using compound microscopy.

Bioremediation is an environmentally sustainable process that employs living organisms—primarily microorganisms—to degrade or neutralize pollutants from contaminated environments. In oil spills and hydrocarbon pollution, bioremediation involves the use of hydrocarbon-degrading bacteria to transform toxic compounds into less harmful substances. This approach leverages natural microbial metabolic processes and is considered both cost-effective and ecologically favorable compared to physical or...

A sustainable auto regulating bacterial system for the remediation of oil pollutions was designed using standard interchangeable DNA parts (BioBricks). An engineered E. coli strain was used to degrade alkanes via β-oxidation in toxic aqueous environments. The respective enzymes from different species showed alkane degradation activity. Additionally, an increased tolerance to n-hexane was achieved by introducing genes from alkane-tolerant bacteria.

Aromatic Hydrocarbon Cations: Structural Overview

Cycloheptatriene is a neutral monocyclic unsaturated hydrocarbon that consists of an odd number of carbon atoms and an intervening sp3 carbon in the ring. The three double bonds in the ring correspond to 6 π electrons, which is a Huckel number, and therefore satisfies the criteria of 4n + 2 π electrons. However, the intervening sp3 carbon disrupts the continuous overlap of p orbitals. As a result, cycloheptatriene is not aromatic. Removing one hydrogen from the intervening CH2 group with both...
FAQs
Specialized epidermal cells produce the compounds before they are deposited on the cuticle, linking cellular activity to the surface profile. Once present, their long-chain hydrocarbon composition supports two functions at once: limiting water loss and carrying chemical information. Variation in chain length, structure, and abundance can therefore affect how a surface is interpreted during ecological and social interactions.
Profiles vary with species, developmental stage, environment, and physiological state. These sources of variation make chemical composition useful for distinguishing organisms and for tracking biological condition or change. They also mean that comparisons should account for life stage and circumstances, because observed differences may reflect more than species identity alone.
Recognition depends on differences in chemical profiles rather than on a single universal hydrocarbon signal. In insects, these profiles can provide information used in mate recognition, species identification, and nestmate discrimination. The same chemical variation can also influence broader social interactions, making surface chemistry relevant to behavioral studies and the organization of insect groups.
Extraction followed by gas chromatography provides a chemical profile of the compounds present on an arthropod's cuticle. Researchers can compare the types, structures, chain lengths, and relative abundances represented in different samples. These comparisons help associate surface chemistry with species, developmental stage, environmental conditions, physiological state, or observed behavior.
CHC profiling supports several areas of biology, including insect ecology, evolutionary biology, systematics, behavior, and pest management. Its value comes from connecting measurable surface chemistry with organismal identity, condition, interactions, and environmental context. The approach can therefore contribute both to studies of how insects relate to one another and to efforts focused on managing pest species.
CHC data should be interpreted alongside species identity, developmental stage, environment, and physiological state. Each factor can contribute to differences in chain length, structure, or abundance, so a chemical contrast may have several possible biological meanings. Considering this context improves interpretation of profiles used in ecological, behavioral, evolutionary, and systematic research.
