Influence of ε-caprolactam on growth and physiology of environmental bacteria

Epsilon-Caprolactam- and Nylon Oligomer-Degrading Bacterium Brevibacterium epidermidis BS3: Characterization and Potential Use in Bioremediation

“…We have shown that the ability of Pseudomonas bacteria to utilize CAP is determined by plasmids (CAP plasmids), which carry genetic information required for the complete mineralization of the xenobiotic [ 11 , 28 ]. Later works described caprolactam-utilizing bacteria of the genera Alcaligenes , Corynebacterium , Acinetobacter , Achromobacter , Arthrobacter , Microbacterium , Bacillus, and others [ 6 , 8 , 9 , 10 , 29 ]. A phylogenetic study of CAP degraders isolated from nylon-6 production wastes attributed them to three phyla: Proteobacteria (Beta- and Gammaproteobacteria), Actinobacteria, and Firmicutes [ 7 ].…”

“…At present, the wastewater is incinerated, and the solid wastes are buried, which leads to the polluting soils and ground waters by caprolactam and its by-products. In several works, CAP is shown to cause dermatitis, fever, and seizures in humans, to induce DNA damage and cause chromosomal aberrations in mammals [ 3 , 4 , 5 ], as well as to inhibit the growth of microorganisms that play important roles in maintaining the ecological equilibrium of soils [ 6 ]. Due to its toxic effect on living organisms, this pollutant poses a hazard to the environment and human health.…”

Draft Genome Sequence of Caprolactam-Degrading Pseudomonas putida Strain SJ3

“…( 5 ). Because of its mass production, vast quantities of wastewater are generated during the manufacturing process, which is mostly discharged into natural water reservoirs without treatment ( 6 ).…”

Determination of optimal growth conditions for gram-positive bacterium Gulosibacter sp. BS38, destructor of toxic xenobiotic epsilon-caprolactam

“…В настоящее время производственные отходы сжигаются или подвергаются захоронению, что приводит к загрязнению почв и грунтовых вод токсичными поллютантами. По литературным данным, КАП вызывает дерматиты, лихорадку и судороги у людей [1], индуцирует хромосомные аберрации у млекопитающих [2], а также ингибирует рост микроорганизмов, играющих важную роль в поддержании экологического равновесия почв [3]. Отсутствие системных исследований микробных деструкторов КАП является фактором, сдерживающим развитие экологичных и экономически выгодных технологий биологической очистки производственных отходов и биоремедиации загрязненных почв.…”
