An efficient lipopeptide biosurfactant (BS) producer, HAK01, was isolated from municipal landfill sites. The strain was able to produce about 4.9 g L lipopeptide at a thermophilic temperature of 45 °C.
Recent research highlights the growing interest in discovering new probiotic strains due to increased market demand, focusing on 15 Lactobacillus isolates from Iranian dairy products.
A novel strain identified as Lactobacillus crustorum KH showed significant properties, including tolerance to acidity, bile, and salinity, along with notable antibacterial activity against harmful bacteria.
In animal studies, both live and heat-killed L. crustorum KH were tested for their protective effects against E. coli O157:H7 in mice, with heat-killed cells offering some protection, though less effective than the live cells.
