“…This was verified in the experiment on the BUT activity. The BUT activity at 36 h was significantly lower than that at 10 h. It has also been reported that BA was used by intestinal cells as an energy source or was degraded by bacteria such as Bacillus , and Rhodococcus , which reduced the content of BA.…”

The aim was to investigate the effect of lotus seed resistant starch (LRS) on lactic acid (LA) conversion to butyric acid (BA) fermented by rat fecal microbiota to construct an acetyl CoA pathway. According to growth curves, the microbiota compositions at 10 and 36 h were further analyzed. The microbiota in the LRS group had higher richness and diversity compared to glucose (GLU) and high amylose maize starch (HAMS). Moreover, LRS and isotope LA promoted the growth of Lactobacillus and Bif idobacterium, promoted BA production, and inhibited the growth of Escherichia−Shigella. The BUT pathway played a dominant role in three groups. At 10 h, Escherichia−Shigella and Bif idobacterium showed a negative correlation with BUT and a positive correlation with BUK, whereas Escherichia−Shigella, Allobaculum, Bif idobacterium, and Ralstonia showed a positive correlation with BUT and BUK at 36 h. [3-13 C] LA was converted to [4-13 C] BA by the isotope labeling technique. Finally, LRS promoted LA conversion to BA mainly by the BUT pathway in intestinal microbiota, especially including Allobaculum, Bif idobacterium, and Ralstonia.

“…These bacterial isolates were well adapted to the pit latrine environment; hence, it is assumed that they have better potential for the degradation of butyric acid in such similar environments. In our previous work [27], nine bacterial strains were found to possess butyric acid-degrading capabilities. analyses.…”

“…Butyric acid degradation by individual pure bacterial strains was assessed at an initial butyric acid concentration of 1000 mg/L in a defined MSM. The choice of 1000 mg/L butyric acid concentration in the present study was based on the butyric acid concentration used for experiments in our previous study [27]. According to Lin et al [17], 90% of pit latrines surveyed in Durban, Nairobi, Kampala, and Pune, and the model toilet had a butyric acid concentration between 46.2 and 1042 mg/L.…”

“…Our previous work showed that Achromobacter xylosoxidans, Bacillus subtilis, Lysinibacillus fusiformis, B. cereus, P.Pseudomonas aeruginosa, Bacillus methylotrophicus, S. marcescens, Achromobacter animicus, and Alcaligenes sp. strain SY1 isolated from pit latrine fecal sludge samples could grow using butyric acid as a sole source of carbon and energy [27]. However, bacteria in natural environments do not live in seclusion, but they dynamically interact with many other bacterial strains in complex multispecies communities [28].…”

In Vitro Study of Butyric Acid Deodorization Potential by Indigenously Constructed Bacterial Consortia and Pure Cultures from Pit Latrine Fecal Sludge

The present study aims at developing an efficient bacterial consortium to biodegrade butyric acid, one of the odor-causing compounds that contribute significantly to pit latrine malodors. Six bacterial strains isolated from pit latrine fecal sludge were selected for the study. Nineteen bacterial consortia of different combinations were artificially constructed. The individual bacterial strains and bacterial consortia were compared by culturing in mineral salt medium supplemented with 1000 mg/L butyric acid as a sole carbon and energy source at pH 7, 30 °C, and 110 rpm under aerobic growth conditions. A co-culture of Serratia marcescens and Bacillus cereus was an effective bacterial consortium compared to individual component bacterial strains and other bacterial consortia, in which 1000 mg/L butyric acid was completely degraded within 16 h of incubation. A temperature of 30 °C and pH 7 were found to be optimum for the maximum degradation for both S. marcescens and B. cereus. The inoculation sizes of 2.0 and 2.5 were optimal for the maximum degradation for B. cereus and S. marcescens, respectively. The study provides insights that will be of substantial help in the development of effective biological treatment technologies for pit latrine odor to change the pit latrine user community’s and would be users’ perception of pit latrines.
