Immobilization of enzymes for synergy in polymers to produce lactose free milk [PDF]

Scientific Reports
Stabilization of the enzyme lactase is of interest in obtaining lactose-free foods. Optimization of the lactase enzyme activity was investigated using various immobilization methods, including encapsulation, and electrospinning.

Baohe pill decoction treats diarrhea induced by high-fat and high-protein diet by regulating lactase-producing bacteria in intestinal mucosa

Frontiers in Microbiology, 2023
IntroductionThis study aimed to investigate the effects of Baohe pill decoction (BPD) on microbial, lactase activity, and lactase-producing bacteria in the intestinal mucosa of mice with diarrhea induced by high-fat and high-protein diet (HFHPD ...

Characterization of putative mannoprotein in Kluyveromyces lactis for lactase production

Synthetic and Systems Biotechnology, 2023
Lactase is a member of the β-galactosidase family of enzymes that can hydrolyze lactose into galactose and glucose. However, extracellular lactase production was still restricted to the process of cell lysis.

Ancient DNA analysis reveals high frequency of European lactase persistence allele (T-13910) in medieval central europe. [PDF]

PLoS ONE, 2014
Ruminant milk and dairy products are important food resources in many European, African, and Middle Eastern societies. These regions are also associated with derived genetic variants for lactase persistence.

The lactase persistence genotype is a protective factor for the metabolic syndrome [PDF]

Genetics and Molecular Biology, 2014
The Metabolic Syndrome (MetS) is defined as a pattern of metabolic disturbances, which include central obesity, insulin resistance and hyperglycemia, dyslipidemia, and hypertension.

Lactase bacteria in intestinal mucosa are associated with diarrhea caused by high-fat and high-protein diet

BMC Microbiology, 2022
Background Excessive fat and protein in food can cause diarrhea by disturbing the intestinal microecology. Lactase is a functional enzyme strongly associated with diarrhea, while lactase bacteria in the intestine are an important source of microbial ...

A worldwide correlation of lactase persistence phenotype and genotypes

BMC Evolutionary Biology, 2010
Background The ability of adult humans to digest the milk sugar lactose - lactase persistence - is a dominant Mendelian trait that has been a subject of extensive genetic, medical and evolutionary research.

Effect of lactase on symptoms and hydrogen breath levels in lactose intolerance: A crossover placebo‐controlled study

JGH Open, 2021
Background and Aim The absence of lactase in the intestinal villi due to mucosal injury or genetic factors causes undigested lactose to reach the colon where it is fermented.

Evolution of Lactase Persistence: Turbo-Charging Adaptation in Growth Under the Selective Pressure of Maternal Mortality?

Frontiers in Physiology, 2021
The emergence of the capacity to digest milk in some populations represents a landmark in human evolution, linking genetic change with a component of niche construction, namely dairying.
