Biological Stability of Water-Based Cutting Fluids: Progress and Application

Chinese Journal of Mechanical Engineering, Год журнала: 2022, Номер 35(1)

Опубликована: Янв. 9, 2022

Abstract The application of cutting fluid in the field engineering manufacturing has a history hundreds years, and it plays vital role processing efficiency surface quality parts. Among them, water-based accounts for more than 90% consumption fluid. However, long-term recycling could easily cause deterioration, breeding bacteria to fail, increase costs, even endanger health workers. Traditional bactericides improve biological stability fluids, but they are toxic environment do not conform development trend low-carbon manufacturing. Low-carbon is inevitable direction sustainable use nanomaterials, transition metal complexes, physical sterilization methods on bacterial cell membrane genetic material effectively solve this problem. In article, mechanism action additives microbial metabolites was first analyzed. Then, denaturation traditional target protein effect were summarized. Further, nanomaterials disrupting potential discussed. effects lipophilicity atomic number complexes penetration also summarized, ultraviolet rays ozone destruction reviewed. other words, bactericidal performance, hazard, degradability, economics various comprehensively evaluated, improving proposed.

Solutions in microbiome engineering: prioritizing barriers to organism establishment

The ISME Journal, Год журнала: 2021, Номер 16(2), С. 331 - 338

Опубликована: Авг. 21, 2021

Abstract Microbiome engineering is increasingly being employed as a solution to challenges in health, agriculture, and climate. Often manipulation involves inoculation of new microbes designed improve function into preexisting microbial community. Despite, increased efforts microbiome inoculants frequently fail establish and/or confer long-lasting modifications on ecosystem function. We posit that one underlying cause these shortfalls the failure consider barriers organism establishment. This key challenge focus macroecology research, specifically invasion biology restoration ecology. adopt framework from summarizes establishment three categories: (1) propagule pressure, (2) environmental filtering, (3) biotic interactions factors. suggest most neglected factor we recommend number actions accelerate solutions.

Inter-bacterial mutualism promoted by public goods in a system characterized by deterministic temperature variation

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Сен. 5, 2023

Abstract Mutualism is commonly observed in nature but not often reported for bacterial communities. Although abiotic stress thought to promote microbial mutualism, there a paucity of research this area. Here, we monitor communities quasi-natural composting system, where temperature variation (20 °C–70 °C) the main stress. Genomic analyses and culturing experiments provide evidence that selects slow-growing stress-tolerant strains (i.e., Thermobifida fusca Saccharomonospora viridis ), mutualistic interactions emerge between them remaining through sharing cobalamin. Comparison 3000 pairings reveals mutualism common (~39.1%) competition rare (~13.9%) pairs involving T. S. . Overall, our work provides insights into how high can favour reduce at both community species levels.

Refining the stress gradient hypothesis in a microbial community

Proceedings of the National Academy of Sciences, Год журнала: 2019, Номер 116(32), С. 15760 - 15762

Microbial species aren’t often found alone, but rather in complex communities containing dozens to hundreds of other species. These affect one another many ways. Species can harm by producing antibiotics, stabbing and injecting toxins, or simply consuming resources that others require (1⇓–3). Microbes also impact positively. They can, for example, degrade antibiotics detoxify the environment, secrete iron-scavenging molecules allow take up iron, excrete metabolic byproducts consume (4⇓–6). The ecology evolution these interactions are becoming more well characterized, it’s unclear whether certain environmental conditions promote form interaction over another. In PNAS, Piccardi et al. (7) demonstrate stress toxic biocides causes between 4 microbial become positive. The gradient hypothesis (SGH) provides a framework predict when positive negative should be observed (8). SGH states facilitation common stressful environments, compared with benign environments where competition (Fig. 1 A ). Since it was proposed, has mainly been tested plant growing (e.g., drought stress) assessing changes nature magnitude their interactions. Metaanalyses have had mixed support (9, 10). Some authors argued predictive power limited lack specificity about which forms cause pattern, how gradients may influence combination (11). study simple community, … [↵][1]1To whom correspondence addressed.

Niche partitioning facilitates coexistence of closely related honey bee gut bacteria

eLife, Год журнала: 2021, Номер 10

Опубликована: Июль 19, 2021

Ecological processes underlying bacterial coexistence in the gut are not well understood. Here, we disentangled effect of host and diet on four closely related Lactobacillus species colonizing honey bee gut. We serially passaged through gnotobiotic bees liquid cultures presence either pollen (bee diet) or simple sugars. Although engaged negative interactions, they were able to stably coexist, both vivo vitro. However, was only possible pollen, sugars, independent environment. Using metatranscriptomics metabolomics, found that utilize different pollen-derived carbohydrate substrates indicating resource partitioning as basis coexistence. Our results show despite longstanding association, interactions can be recapitulated vitro providing insights about when combined with experiments.
