An alternative protein ingredient based on spray-dried, hydrolyzed red blood cells was evaluated in calf milk replacers. Two experiments were conducted to determine the value of the ingredient on intake, growth, and feed efficiency in dairy calves. In experiment 1, Holstein bull calves (n = 120) were fed calf milk replacer containing 0, 11, 22, or 43% of crude protein as spray dried hydrolyzed ...

Cheesemaking from batches of raw ewe’s milk was carried out via inoculation with wild strains of Lactococcus lactis subsp. lactis ESB110019 and Lactobacillus plantarum ESB5004 independently, or combined with each other. Those two strains had been isolated from the native microflora of typical Serra da Estrela cheese. One control batch was processed in parallel without addition of any starter. T...

A detailed investigation was undertaken to determine the effects of four single starter strains, Lactococcus lactis subsp. lactis 303, Lc. lactis subsp. cremoris HP, Lc. lactis subsp. cremoris AM2, and Lactobacillus helveticus DPC4571 on the proteolytic, lipolytic and sensory characteristics of Cheddar cheese. Cheeses produced using the highly autolytic starters 4571 and AM2 positively impacted...

Enturire is an alcoholic sorghum- and honey-based beverage traditionally produced by spontaneous fermentation. Its fermentation process is lengthy (5-7 days), does not guarantee product quality and safety and thus necessitates use of pure starter cultures. This study compared a modified production process of Enturire, with honey added at the start to the traditional one (honey added 3 days into...

Cocoa pulp fermentation is a spontaneous process during which the natural microbiota present at cocoa farms is allowed to ferment the pulp surrounding cocoa beans. Because such spontaneous fermentations are inconsistent and contribute to product variability, there is growing interest in a microbial starter culture that could be used to inoculate cocoa pulp fermentations. Previous studies have r...

The amino acid conversion to volatile compounds by lactic acid bacteria is important for aroma formation in cheese. In this work, we analyzed the effect of the lytic bacteriocin Lacticin 3147 on transamination of isoleucine and further formation of the volatile compound 2-methylbutanal in cheese. The Lacticin 3147 producing strain Lactococcus lactis IFPL3593 was fluorescently tagged (IFPL3593-G...

A completely randomised design was performed to evaluate the effect of inclusion of egg powder in the pre-started diet (1-7 day age) on the immune response of male broiler chickens. Experimental pre-starter diets formulated to have 0, 20, 40 or 60 g/kg egg powder. The relative weight of lymphoid organs (spleen and bursa) was reduced, in days 7 and 42 of age, by graded inclusion of egg powder in...

This is the first report on the microbial diversity of xaj-pitha, a rice wine fermentation starter culture through a metagenomics approach involving Illumine-based whole genome shotgun (WGS) sequencing method. Metagenomic DNA was extracted from rice wine starter culture concocted by Ahom community of Assam and analyzed using a MiSeq® System. A total of 2,78,231 contigs, with an average read len...

The trial was conducted to evaluate the effect of different levels of dried sweet orange (Citrus sinensis) peel on growth performance in broilers. A total of 400 male broiler chicks (Ross-308) were randomly allocated to treatments varying in supplemental DSOP. The dietary groups consisted of five diets fed for 42 days: control diet without feed additive, diet containing 1.5 % feed additive only...

We investigated the possibility of using starter cultures in sauerkraut fermentation and thereby reducing the quantity of salt used in the process. This, in turn, would reduce the amount of waste salt that would enter in our water resources. Phage, naturally present in sauerkraut fermentation, could potentially affect the starter cultures introduced. Thus, a mechanistic mathematical model was d...
