Internal tubing involved in the venting and vacuum mechanism of CooperVision's models 8000-V, 7500, and 6500 units were cultured. Several species of bacteria were found including Staphylococcus epidermidis. The clinical implications of this are discussed as well as a solution to the possibility of intraoperative bacterial contamination from the reported source.

The role of carbon and nitrogen ratio on sewage sludge microbiota for producing polyhydroxyalkanoates.

Engineering Department, University of Palermo, Viale delle Scienze, Ed. 8, 90128, Palermo, Italy.
The products of an advanced sewage sludge fermentation process can be used to generate polyhydroxyalkanoates (PHAs), precursors of bioplastics considered excellent candidates for replacing petroleum-derived plastics. The aerobic feast-anoxic famine cycling strategy has proven to be an efficient method for enriching sewage sludge microbiota with PHA-producing microorganisms. This work evaluated the effect of different carbon to nitrogen ratios (C/N) of 3.

The limited understanding of microbial response mechanism remains as a bottleneck to evaluate the long-term remediation effectiveness of in situ chemical oxidation in contaminated groundwater. In this study, we investigated long-term response of bacterial communities throughout five remediation stages of pre-oxidation, early-oxidation, late-oxidation, early-recovery and late-recovery. By analyzing bacterial biomass, taxa, diversity and metabolic functions, this work identified the consistently suppressed glyceraldehyde-3-phosphate dehydrogenase pathway and the enrichment of naphthalene degradation pathways for secondary products, suggesting persistent oxidation stress and enhanced microbial utilization of lower-molecular weight carbon sources at the oxidation and early-recovery stages.

Sexual reproduction and recruitment enhance the genetic diversity and evolution of reef-building corals for population recovery and coral reef conservation under climate change. However, new recruits are vulnerable to physical changes and the mechanisms of symbiosis establishment remain poorly understood. Here, , a broadcast spawning hermaphrodite reef-building coral, was subjected to settlement and juvenile growth in flow-through seawater at 27.

As bacterial contamination crises escalate, the development of advanced membranes possessing both high flux and antibacterial properties is of paramount significance for enhancing water sterilization efficiency. Herein, an ultrathin layer of TbPa (an imine-linked covalent organic framework) and nanosized CuO clusters, sequentially deposited onto polyethersulfone membranes, demonstrate exceptional water flux performance, reaching a permeance level of 16000 LHM bar. The deposited TbPa, generating uniformly distributed reduction sites under illumination, facilitates the uniform formation of CuO clusters.

Hyperaccumulators harbor potentials for remediating rare earth elements (REEs)-contaminated soils. However, how they thrive in low-nutrient abandoned REEs mining sites is poorly understood. Three ferns (REEs-hyperaccumulators Dicranopteris pedata and Blechnum orientale, and non-hyperaccumulator Pteris vittata) along with their rhizosphere soils were collected to answer this question by comparing differences in soil nutrient levels, soil and plant REEs concentrations, and bacterial diversity, composition, and functions.
