Inhibition of Growth of Selected Bacterial Species Through the Use of Methanolic Maceratives of Black Soldier Fly Pre-Pupae

Abstract

The attempt is dealing with of analysis of effect of maceratives of prepupal stages of black soldier fly (BSF) (Hermetia illuncens L.) in methanol on the inhibition of the growth of selected bacterial species. The bacterial species used for the study include: Salmonella typhimurium (L.); Escherichia coli (L.); Pseudomonas aeruginosa (L.); Bacillus cereus (L); Bacillus subtilis (L); Streptococcus cremoris (L); Streptococcus faecalis (L); Staphylococcus aureus (L); Klebsiella pneumoniae (L); Salmonella enterica (L) and Proteus vulgaris (L). Various strengths in ppm (mg/Lit) of methanol maceratives of prepupal stages of black soldier fly used in the study include: 50; 100; 150; 200; 250 and 300. The diameter (mm) of growth inhibition zone in the bacterial species in the attempt through the use of standard antibiotic compound (chloramphenicol) was found measured 14.76 mm to 35.78 mm. The use of methanol maceratives of prepupal stages of black soldier fly was reported inhibiting the growth bacterial species in the attempt. The bacterial growth inhibition for the methanol maceratives of prepupal stages of black soldier fly zone was ranging from 7.13 (± 0.27) to 20.55 (± 4.93) mm units. The use of methanol maceratices of prepupal stages of black soldier fly is highlighting the potential challenges towards the efforts on developing therapeutic antibacterial product.
