Abstract

The Endophytic bacteria as a biofertilizer agent can minimize the use of chemicals from synthetic fertilizers. The aim of this research was to study the density, diversity and ability of endophytic bacteria from coffee plants that have the potential to produce IAA. Root samples were obtained from coffee plants in UB Forest (UBF), Sumberwangi, Malang. The root samples were surface sterilized and then crushed with a blender. Endophytic bacteria were isolated and tested for their potential to produce IAA. The results obtained were 18 isolates of IAA-producing bacteria. KAA6 Isolate were produced the highest concentration of IAA of 10.73 ppm at 48 hours of incubation followed by KBA3 isolate which produced 12.78 ppm of IAA at 72 hours of incubation. The potential bacteria can be further optimized to be used as an eco-friendly biofertilizer agent.

Abstract

Food safety and sustainable food production is an essential parts of the sustainable development goals of protecting the health and well-being of humans, animals, and the environment. Foodborne diseases are a significant cause of morbidity and mortality, particularly with the global crisis of antibiotic resistance. Bacteriophages as a biocontrol are a promising alternative for reducing contamination from pathogenic bacteria in food such as Escherichia coli, Bacillus cereus, Staphylococcus aureus, and Listeria monocytogenes. Bacteriophages are natural predators of bacteria that are harmless to humans and animals and are found in various environments, thus have been recognized as promising antimicrobial agents to help control specific bacterial pathogens in food production. Several bacteriophages have been applied in food to reduce the number of pathogenic bacteria. The results of this application show the efficacy of bacteriophages as biopreservation agents against foodborne pathogenic bacteria.
