“…FND3, and Paracoccus sp. YM3 efficiently removed 80% methomyl within 7 days as compared to the 40-day degradation period of Flavobacterium and Alcaligenes [76,77,85,87]. Interestingly, some bacteria can degrade methomyl as well as other pesticides, such as aldicarb, oxamyl, fenamiphos, and Imidacloprid [75,79,84,86].…”

“…CBS 237.37, was isolated to degrade methomyl, carbaryl, carbofuran, and carbofuran [88]. In addition, two strains of genetically engineered bacteria have also been successfully used to degrade methomyl [85,86]. Taking into account the contamination of the environment with various pesticides and the adaptability of indigenous micro-organisms to the environment, genetic engineering techniques may accelerate the application of degrading micro-organisms in situ.…”

Methomyl is a broad-spectrum oxime carbamate commonly used to control arthropods, nematodes, flies, and crop pests. However, extensive use of this pesticide in agricultural practices has led to environmental toxicity and human health issues. Oxidation, incineration, adsorption, and microbial degradation methods have been developed to remove insecticidal residues from soil/water environments. Compared with physicochemical methods, biodegradation is considered to be a cost-effective and ecofriendly approach to the removal of pesticide residues. Therefore, micro-organisms have become a key component of the degradation and detoxification of methomyl through catabolic pathways and genetic determinants. Several species of methomyl-degrading bacteria have been isolated and characterized, including Paracoccus, Pseudomonas, Aminobacter, Flavobacterium, Alcaligenes, Bacillus, Serratia, Novosphingobium, and Trametes. The degradation pathways of methomyl and the fate of several metabolites have been investigated. Further in-depth studies based on molecular biology and genetics are needed to elaborate their role in the evolution of novel catabolic pathways and the microbial degradation of methomyl. In this review, we highlight the mechanism of microbial degradation of methomyl along with metabolic pathways and genes/enzymes of different genera.

Rational lifestyle engineering using computational methods and synthetic biology has made it possible to genetically improve industrial performance of microbial cell factories for the production of a range of biobased chemicals. However, only an estimated 1 in 5,000 to 10,000 innovations make it through the Valley of Death to market implementation.To gain in-depth insights into the views of industry and academia on key bottlenecks and opportunities to reach market implementation, a qualitative and exploratory study was performed by conducting 12 in depth interviews with 8 industrial and 4 academic participants. The characteristics that any cell factory must have were schematically listed, and commonly recognised opportunities were identified.We found that academics are limited by only technical factors in their research, while industry is restricted in their research choices and flexibility by a series of technical, sector dependent and social factors. This leads to a misalignment of interest of academics and funding industrial partners, often resulting in miscommunication. Although both are of the opinion that academia must perform curiosity-driven research to find innovative solutions, there is a certain pressure to aim for short-term industrial applications. All these factors add up to the Valley of Death; the gap between development and market implementation. A third party, in the form of start-up companies, could be the answer to bridging the Valley of Death.

Bioremedijacija se koristi potencijalom mikroorganizama pri uklanjanju onečišćenja iz okoliša. Metabolički putovi kojima se onečišćujuća tvar razgrađuje u manje toksične tvari vrlo su kompleksni. Naprednim tehnikama molekularne biologije mehanizmi bioremedijacije izučavaju se na razini gena. Gen zaslužan za proizvodnju proteina koji razgrađuje onečišćujuću tvar može se izolirati i unijeti u drugi organizam, čime nastaje organizam s poboljšanim bioremedijacijskim svojstvima. Brojna se svjetska istraživanja temelje na genetičkom inženjerstvu na mikroorganizmima, no najveću prepreku upotrebe takvih organizama u bioremedijaciji čine zakonski okviri te nedovoljno poznavanje posljedica njihova oslobađanja u okoliš.
