Abstract

The content of active compounds in natural materials is generally low and highly variable, thus requiring efficient and selective extraction methods. This study aims to evaluate a stepwise extraction process applied to the seeds, oil, and by-products of Nigella sativa (black cumin) to obtain thymoquinone (TQ) and other phytochemicals. The study consisted of four main stages: (1) extraction of HS oil using the cold press method, (2) stepwise extraction using 70% ethanol as solvent, (3) analysis of TQ content and phytochemical compounds in the extracts, and (4) evaluation of the antibacterial activity of habbatussauda oil extracts against pathogenic and non-pathogenic bacteria. Results showed that the cold press method yielded 34.46% oil. Stepwise extraction using 70% ethanol resulted in significant differences (p<0.05) in both yield and TQ content among the seed, oil, and by-product extracts. Among all samples, the ethanol extract from habbatussauda oil exhibited the highest yield and TQ concentration. Furthermore, at a concentration of 100 μg mL⁻¹, this extract inhibited the growth of pathogenic bacteria such as Salmonella typhimurium and Escherichia coli, without affecting non-pathogenic strains like Lactobacillus spp. and Bifidobacteria spp. In conclusion, stepwise extraction using 70% ethanol proved effective in enhancing TQ recovery and demonstrated potential as a phytobiotic agent with selective antibacterial activity against pathogenic bacteria.

Abstract

The growth rate of chickens can be improved by using probiotics as alternatives to antibiotics. Bacillus spp. as probiotics are particularly beneficial due to ability to form spores, which remain stable as commercial products over extended periods. This study aimed to isolate and select Bacillus spp. from Jasinga soil as probiotic candidates for chickens. A total of 15 isolates obtained of these, 12 were identified as Bacillus spp based on microscopic observations and screening test including ascertaining hemolysis, protease, amylase, and cellulase activities. Only six isolates exhibited gamma hemolysis and the ability to hydrolyze proteins, starch, and cellulose. Isolates BTJ1.1, 1.2, 1.4, and 2.3 poliferated in 0.3% bile salts. BTJ1.1, 1.2 and 2.3 also exhibited antimicrobial activity and sensitivity to amoxicillin, tetracycline, and rifampicin. BTJ1.1 and 2.3 were highly hydrophobic, a key probiotic trait. 16S rRNA gene sequence analysis revealed that BTJ1.1 and 2.3 were >99% similar to B. amyloliquefaciens strain B54 and B. subtilis strain ASI3, respectively, highlighting their potential as probiotics.

Abstract

The use of Antibiotic Growth Promoters (AGPs) in the poultry industry led to farmers’ dependence on antibiotics. Therefore, a safer alternative feed additive, such as fulvic acid, was needed. This study aimed to evaluate the effectiveness of fulvic acid extracted from oil palm empty fruit bunches (FA-OPEFB) as a feed additive on broiler chickens’ digestive tract and intestinal morphology. A total of 150 broiler chickens were used in a Completely Randomized Design (CRD) consisting of three treatments and five replications: P0 (drinking water without FA-OPEFB), P1 (drinking water with 0.1% FA-OPEFB), and P2 (drinking water with 0.2% FA-OPEFB). Observed variables included the relative weight and length of the digestive tract and intestinal morphology. The results showed that the addition of FA-OPEFB in drinking water significantly affected the ileum percentage, villus height, crypt depth, and villus surface area. It was concluded that 0.2% FA-OPEFB in drinking water reduced the relative weight and length of the ileum and improved intestinal morphology in broiler chickens. Key words:           broiler chicken, digestive tract, fulvic acid, intestinal morphology, OPEFB
