Batch and semi-continuous fermentation with Parageobacillus thermoglucosidasius DSM 6285 for H production.

Background: Parageobacillus thermoglucosidasius is a facultatively anaerobic thermophile that is able to produce hydrogen (H) gas from the oxidation of carbon monoxide through the water-gas shift reaction when grown under anaerobic conditions. The water-gas shift (WGS) reaction is driven by a carbon monoxide dehydrogenase-hydrogenase enzyme complex. Previous experiments exploring hydrogenogenesis with P.

Factors influencing COVID-19 vaccine acceptability among household heads in northern Nigeria: a community-based cross-sectional study.

Objectives: COVID-19 vaccine was rolled out for the public in August 2021 in Zamfara state, Northen Nigeria. We determined the factors influencing COVID-19 vaccine acceptance.

Settings: We executed a community-based analytical cross-sectional study during the first 4 months of the second phase of the COVID-19 (Oxford/AstraZeneca) mass vaccination campaign in Zamfara state.

HISTOPATHOLOGY OF ACUTE APPENDICITIS IN CHILDREN IN ZARIA.

Introduction: Appendicitis is a common cause of acute abdomen. Although many guidelines exist to aid in the preoperative diagnosis of appendicitis in children, histology remains the definitive diagnostic method. Histological diagnosis is premised on the presence of inflammatory infiltrates beyond the mucosa and involving the submucosa and muscularis propria.

Stirring the hydrogen and butanol production from Enset fiber via simultaneous saccharification and fermentation (SSF) process.

Enset fiber is a promising feedstock for biofuel production with the potential to reduce carbon emissions and improve the sustainability of the energy system. This study aimed to maximize hydrogen and butanol production from Enset fiber through simultaneous saccharification and fermentation (SSF) process in bottles as well as in bioreactor. The SSF process in bottles resulted in a higher butanol concentration of 11.

Immuno-protective effect of commercial IBD vaccines against emerging novel variant infectious bursal disease virus in specific-pathogen-free chickens.

Importance: Infectious bursal disease (IBD) is an important viral poultry disease that vaccination can control.

Objective: This study examined the immune protection of immune-complex (Vaccine A) and attenuated live (Vaccine B) IBD vaccines in specific-pathogen-free (SPF) chickens against a novel Malaysian variant IBD virus (vaIBDV) challenge.

Methods: One-day-old (n =75) SPF chickens were divided randomly into the following three groups of 25 chicks each: Control, Vaccine A, and Vaccine B groups.
