To produce processed cheese turning hardly brown during transportation and storage at room temperature, natural cheese showing less discoloration should be used as a raw material. The purpose of this study was to clarify the relationship between the lactose utilization of lactic acid bacteria and the browning of cheese during storage. Three type-cultures ( and ) and five isolates from Japanese pickles ( spp.) were used. Cheese curds inoculated with these bacteria were prepared and stored. The -inoculated curds showed smaller Δ-values after storage, an indicator for the browning, compared to the others. Accumulation of galactose was observed in the curd to which was inoculated. The sample showed larger Δ-value after storage. These results showed the lactose utilization of bacteria affected galactose concentration in cheese and its browning during storage. might be a good starter for preparing cheese turning hardly brown.

Alkaline pectinases are in demand in industrial processes that require the degradation of plant pectins at high pH, for example, removal of pectin stains from fabrics, cutlery, and porcelain; treatment of pectic wastewater; fermentation of coffee, tea, and cocoa; manufacture of poultry and animal feeds, and processing of textiles, and so forth. The present study aimed to (a) screen four alkaliphilic microbial isolates, previously obtained from samples collected around Lake Bogoria (soda lake), Baringo County, Kenya, for alkaline pectinases, and (b) characterize the pectinase-producers. The screening data revealed that all the isolates were pectinase producers, exhibiting catalytic activities that ranged from 1.

Reducing nitrogen loss and improving nitrogen utilization efficiency in dairy cows can reduce economic costs and mitigate the environmental impact of nitrogen emissions. Red clover isoflavone, a natural compound derived from plant extract, has the advantage of biological safety. This study aimed to investigate the effects of red clover isoflavone on lactation performance and nitrogen metabolism in dairy cows.

Lactase persistence is a genetically inherited trait that enables continued lactose digestion into adulthood. Lactase non-persistence (LNP) individuals often experience incomplete lactose digestion, allowing undigested lactose to reach the colon, where it may shape microbial composition and function. We investigated the relationship between the lactase persistence (LP) genotype, lactose consumption, and the taxonomic and functional profiles of the fecal microbiome.
