ethanol production
No full textBACKGROUND: The production of second-generation (2G) ethanol from lignocellulosic biomass generates large quantities of
high-strength complex wastewaters from various stages of the process. An effective pretreatment is necessary in order to overcome
the low biodegradability of these wastewaters for further biomethane recovery. The present study reports the effect of
ozonation on the biodegradability enhancement and biomethanation potential of complex 2G ethanol pretreatment process
wastewaters, from acid (H2SO4) and alkali (NaOH) pretreatment process.
RESULTS: Ozonation(9.33 g m−3)was performedfor both acid and alkali pretreatment wastewaters at aflowrate of 10 L min−1 for 1 h.
Ozonation of bothwastewaters increased biodegradability index (BI) up to 36% alongwithminimal chemical oxygen demand (COD; 7
± 3%), color (10 ± 4%), and toxicity (22.5 ± 7.5%) reduction. Biomethane potential tests were carried out for the control and ozonated
wastewaters having BI > 0.4. The acid-pretreatment wastewater indicated poor biomethanation potential due to high presence of sulfates
(COD/SO4 ∼ 3.0).However, ozonation of alkali-pretreatment wastewater facilitated up to twofold enhancement in the cumulative
methane volume,while theenhancementin the rateofmethane productionwasfoundto beupto 47%.Fourier transform infrared spectroscopic
analysis of control and ozonated wastewaters revealed the breakdown of complex organicmolecules and aromatics to readily
biodegradable intermediates. The kinetics ofmethane generation could be predicted by the modified Gompertz model.
CONCLUSION: The study demonstrated the efficacy of ozonation as an effective pretreatment option to facilitate biodegradability
enhancement of 2G ethanol pretreatment process wastewaters. The enhancement in biodegradability was observed
to enable subsequent biogas recovery via anaerobic digestion along with COD removal

Verschreibungspraxis für Antibiotika zur Prophylaxe und Theapie oraler/dentaler Infektionen bei pädiatrischen Patienten - Ergebnisse einer Querschnittsstudie in der Türkei
No full textAim: Antibiotics are often prescribed for the treatment of various infections and prophylactic purposes in dental practice. Their improper use can cause microbial resistance to antibiotics, which poses a world-wide threat. The aim of this cross-sectional study was to evaluate the knowledge and attitudes of dentists and dentistry students about antibiotic prescription practices for prophylaxis and the treatment of dental infections in pediatric patients.Methods: A questionnaire was e-mailed to 2,100 dentists and 300 senior dentistry students. The questionnaire was filled out by the participants within a 2-month period (May-June 2020). A 30-point scoring system was developed to assess the knowledge levels of the dentists according to the guidelines. Descriptive statistical analyses were performed. One-way ANOVA test and the Chi-Squared test were used to compare qualitative variables.Results: The response rate was found to be 24.2% for dentists and 49% for senior dentistry students. 19.4% of the participants were found to be moderately knowledgeable and 80.6% of them were highly knowledgeable. Students' knowledge scores were found to be higher than the general dentists and other specialists (p<0.05). There was no significant difference between students and pedodontists.Conclusion: Dentists were found to have sufficient knowledge about the usage of antibiotics in children, but there is still a lack of information about circumstances under which antibiotics should not be prescribed. Dentists and dentistry students should attend continuing education programs to keep their information up-to-date and should also prescribe antibiotics in adherence with the current guidelines to prevent antibiotic resistance.Zielsetzung: Antibiotika werden aus prophylaktischer und therapeutischer Indikation in der Zahnarztpraxis verschrieben. Der unsachgemäße Einsatz von Antibiotika kann zu mikrobiellen Resistenzen gegen Antibiotika führen und stellt eine weltweite Bedrohung dar. Ziel der Querschnittsstudie war es, das Wissen und die Einstellungen von Zahnärzten und Zahnmedizinstudenten zur Entscheidung über die Verschreibung von Antibiotika zur Prophylaxe und Behandlung von odontogenen Infektionen bei pädiatrischen Patienten zu evaluieren.Methode: Per E-Mail wurde ein Fragebogen an 2.100 Zahnärzte und 300 Zahnmedizinstudenten im fortgeschrittenen Studiengang versandt. Der Fragebogen wurde von den Teilnehmern innerhalb von 2 Monaten (Mai-Juni 2020) ausgefüllt. Zur Bewertung des Wissensstandes der Zahnärzte gemäß den Leitlinien wurde ein 30-Punkte-Score-System entwickelt. Deskriptive statistische Analysen wurden durchgeführt. Der Einweg-Anova-Test und der Chi-Quadrat-Test wurden zum Vergleich qualitativer Variablen verwendet.Ergebnisse: Die Rücklaufquote betrug 24,2% bei Zahnärzten und 49% bei Zahnmedizinstudenten. 19,4% der Teilnehmer wurden als mittelmäßig, 80,6% als sehr gut informiert eingestuft. Die Wissensscore der Studenten waren höher als die der allgemeinen Zahnärzte und anderer Spezialisten (p<0,05). Es gibt keinen signifikanten Unterschied zwischen Studenten und Kinderzahnärzten.Schlussfolgerung: Es wurde festgestellt, dass Zahnärzte ausreichende Kenntnisse über die Verwendung von Antibiotika bei Kindern haben, aber es gibt immer noch einen Mangel an Informationen, wann Antibiotika nicht verschrieben werden sollten. Zahnärzte und Zahnmedizinstudenten sollten an Fortbildungsprogrammen teilnehmen, um ihre Informationen auf dem neuesten Stand zu halten, und sollten Antibiotika gemäß den aktuellen Richtlinien verschreiben, um Antibiotikaresistenzen vorzubeugen
