Peptobiotics

Solving antibiotic resistance in agriculture with small peptidesPeptobiotics founder and CEO Jonathan Bester comes from an oil family; his father and two uncles are in the industry. And at one point, while working at an algae biotechnology start-up, Bester hoped to disrupt the oil industry with environmentally sustainable alternatives.But when that company pivoted, Bester took matters into his own hands and decided to start his own firm. He wanted to find a green solution to a modern problem; his idea was to replace commonly used antibiotics in animal agriculture with microorganism-derived antimicrobial peptides.Human pathogens are becoming more resistant to antimicrobials, in part because of the overuse of antibiotics in agriculture to prevent disease and promote growth. But microbes have been at war with one another for resources since the dawn of life on Earth, and they produce their own antimicrobial peptides—peptides Bester thought could be useful in an agricultural setting.Pursuing that idea meant leaving his home in the UK. “Europe just was not a suitable place to start this kind of company, because the route to market takes so long,” he says. “So I moved to Southeast Asia.”Bester landed in Singapore during the COVID-19 pandemic lockdown, and it was exceptionally difficult to build a new base of operations. He was briefly connected with a cofounder in a collaboration that didn’t end up working out. “I was a little bit lost,” Bester says. “I needed someone who could help me build the technology. And so I asked another entrepreneur . .
