Evaluasi Sifat-Sifat Probiotik Lactiplantibacillus Plantarum Dan Lacticaseibacillus Paracasei Yang Diisolasi Dari Dadih Kabupaten Kampar Secara Mikroenkapsulasi Atau Tanpa Mikroenkapsulasi
ABSTRACT
Dadih is a fermented product made from buffalo milk involving lactic acid
bacteria as probiotic agents in bamboo tubes. The effectiveness of probiotics is seen
from the hydrophobicity of the cell surface, autoaggregation, and coaggregation.
The purpose of this study was to determine the ability of cell surface
hydrophobicity, autoaggregation, and coaggregation of Lactiplantibacillus
plantarum strain HBUAS62562 ON005210 and Lacticaseibacillus paracasei strain
MT544959.1 4432 isolated from dadih with and without microencapsulation with
skim milk. This study was carried out experimentally using a complete randomized
design (CRD) with four treatments of Lactiplantibacillus plantarum strain
HBUAS62562 ON005210 and Lacticaseibacillus paracasei strain MT544959.1
4432 isolated from dadih with and without microencapsulation with skim milk, and
each treatment was repeated four times, resulting in 16 experimental units. The
results showed that Lactiplantibacillus plantarum strain HBUAS62562 ON005210
and Lacticaseibacillus paracasei strain MT544959.1 4432 isolated from dadih with
and without microencapsulation with skim milk significantly affected the values of
hydrophobicity, autoaggregation, and coaggregation. Microencapsulation with
skim milk increased cell surface hydrophobicity (46,25–54,13%) and
autoaggregation (19,25–28,1%) of both bacteria. Coaggregation with lactic acid
bacteria was lower (6,94–8,56%) compared to Salmonella sp. (9,5–10,87%) and
Listeria monocytogenes (8,34–10,09%).
