BACKGROUND Intermediates from processing sugar beets are considered an attractive feedstock for ethanol fermentation due to their high fermentable sugar content. In particular, medium prepared from raw sugar beet juice seems to be suitable for use in fermentation processes, but it is microbiologically unstable and requires sterilization. RESULTS This study investigates the effect of ozone tre...

In this paper, we report a UV/ozone-assisted method for low temperature preparation of mesoporous TiO2 with controlled crystalline phase. The results showed that the crystallization of mesoporous TiO2 can occur at temperatures as low as 100 C under UV/ozone irradiation. Highly crystalline mesoporous anatase TiO2 was obtained after UV/ozone treatment at 200 C. The phase transformation from anata...

The applicability of a sequential process of ozonation and ozone/hydrogen peroxide process for the removal of soluble organic compounds from a pre-coagulated municipal sewage was examined. 6-25% of initial T-CODCr was removed at the early stage of ozonation before the ratio of consumed ozone to removed T-CODCr dramatically increased. Until dissolved ozone was detected, 0.3 mgO3/mgTOC0 (Initial ...

Changes in proximate composition, colour and textural characteristics of ozone-processed shrimp as affected by combined effects of increasing ozone exposures and iced storage were investigated and for the first time. Whilst proximate composition comprised of fat, moisture, and protein contents and colour comprised of L*, a*, b* and metric chroma (C), the texture comprised of adhesiveness, fract...

Gaseous emerging organic compounds (GEOCs) may harm human health and ecological environment. High temperature composting of livestock manure produce oxytetracycline (OTC) waste gas. Here, we investigated treatment OTC in gas by combined ozone membrane biofilm reactor (MBfR) with desulphurizing bacteria. The performance, the microbial community, gene function mechanism for removal ozone-MBfR wer...

Ozone has been shown to clinically reverse carious lesions in previous studies. This study aimed to assess a single 20-second dose of ozone to manage primary occlusal pit and fissure carious lesions in a general dental practice over a 24-month time period. Treatment of the carious lesion consisted of thorough prophylaxis of the occlusal surface, treatment with ozone or compressed air for 20 sec...

The purpose of the current study is to evaluate formaldehyde degradation ratio with various methods in a batch reactor. In this work, the ozonation, sonolysis (ultrasonic), and ozone sonolysis, sono catalytic ozonation (SCO), and nano zero-valent iron catalyst processes were investigated for removal of formaldehyde. In addition, the influence of important factors such as pH (5–9), ultrasonic po...

Gas phase treatments of dry-fiberized newsprint were investigated as a way to impmve intefibre bonding and thereby to minimize the use of water for recycling newsprint. Chlorine dioxide, nitrogen dioxide, and ozone were studied as gaseous oxidizing agents. The report includes the results of an optimization study for the ozone treatment and results of experiments designed to establish the mechan...

BACKGROUND Ozone increases IL-33 in the lungs, and obesity augments the pulmonary effects of acute ozone exposure. OBJECTIVES We assessed the role of IL-33 in the augmented effects of ozone observed in obese mice. METHODS Lean wildtype and obese db/db mice were pretreated with antibodies blocking the IL-33 receptor, ST2, and then exposed to ozone (2 ppm for 3 hr). Airway responsiveness was ...
