Njalam'mano, John Bright Joseph; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2019)Achromobacter xylosoxidans is one of the bacterial strains that have the capability to degrade butyric acid which significantly contribute to malodours from pit latrines emissions. There is an increasing interest in being ...

Njalam'mano, John Bright Joseph; Chirwa, Evans M.N.; Seabi, Refilwe Lesego (MDPI Publishing, 2020-06-24)The present study aims at developing an e cient bacterial consortium to biodegrade butyric acid, one of the odor-causing compounds that contribute significantly to pit latrine malodors. Six bacterial strains isolated ...

Njalam'mano, John Bright Joseph; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2018)Biodegradation of butyric acid was investigated in mineral salt medium (MSM) with a novel bacterial strain B6a. The molecular identification based on 16S rRNA sequence analysis revealed the bacterial strain B6a as ...

Njalam'mano, John Bright Joseph; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2018)Butyric acid is one of the volatile organic compounds that contribute significantly to pit latrine offensive smell. The objective of this work was to isolate, identify and characterize pure butyric acid-utilising bacteria ...

Njalam'mano, John Bright Joseph; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2019)Waste volatile compounds, such as butyric acid, generated from pit latrines may cause discomfort to pit latrine users and they have undesirable impacts on sanitation promotion efforts and public health. The purpose of this ...
