“…These probiotic bacteria, commonly found in the digestive tract of humans and animals [27], contribute to the absorption of nutrients and produce organic acids that inhibit the growth of harmful bacteria in the intestine. The higher population of lactic acid bacteria colonies resulting from the eco enzyme treatment supports these beneficial effects [28].…”

Eco enzymes are derived from the fermentation of organic matter, particularly fruit and vegetable peels, offering the advantage of being a versatile natural cleaning solution. They also serve as essential nutrients for plant and algae growth, while converting CO2 into carbon trioxide (CO3), which benefits marine plants and aquatic life. This study aimed to investigate the impact of providing alternative feed/companion in the form of eco enzyme liquid, composed of 90% organic matter from three types of fruit peels and 10% vegetable residues from fern plants, on the growth of Pangasius djambal in conventional fish ponds with peat water. The implementation of 1 litre of ecoenzyme per 100 ml of peat water in the fish ponds led to the enhancement of Pangasius djambal, resulting in increased weight and varying lengths. The correlation coefficient (>1) indicates a strong relationship between fish weight and length, suggesting that the total weight of the fish is directly proportional to its length. Moreover, the water quality standards, including physical, chemical, and biological parameters, in the conventional fish enlargement ponds with peat soil pond water type were well-maintained, preventing contamination from feed residues and fish feces, even after 28 days of fish enlargement.

“…The bacterial culture was prepared using the spectrophotometer reading of the turbidity of bacterial cell suspension. All the bacteria used in this study qualified for the suspension culture [32]. A single colony from the nutrient agar culture of each bacterium was inoculated into four tubes, each containing 10 mL nutrient broths.…”

“…A different form, such as hydrogel, a natural structure, is a gel form with the disc diffusion assay that can effectively study the antibacterial activities of sticky-type products. Adding different concentrations of carrageenan extract in antibacterial activity will not influence the outcome of the study [32]. These forms will require a completely different methodology to be applied.…”

The abuse of synthetic antibiotics is one of the leading causes of the emergence of antibiotic-resistant microorganisms that have become the primary health concern. To overcome this resistance and counteract all the side effects of synthetic drugs, attention was diverted towards natural resources for developing antimicrobial substances. This study tests the effect of carrageenan isolated from Kappaphycus alvarezii on pathogenic bacteria. Carrageenan is a natural bioactive compound extracted from red algae. Carrageenan was extracted from K. alvarezii using hot water extraction. The antimicrobial property of carrageenan was tested using the Minimum Inhibitory Concentration and the bacterial cell growth rate. Moreover, a commercial antibacterial hand wash and anti-acne toner were used as comparative agents. Firstly, a series of concentrations were used, from 25 µg/mL to 10 mg/mL. The results showed no antimicrobial activity of carrageenan extracted from K. alvarezii using ethanol toward the strains used in this study, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Staphylococcus aureus. However, the carrageenan extracted exhibited a growth-boosting effect over the microorganisms used. Thus, further studies can be carried out using different carrageenan extract methods for K. alvarezii to ensure that anti-microbial compounds from K. alvarezii can be extracted during the carrageenan extraction.
