“…On the other hand, it has been shown that the presence of heavy metals such as iron induces the process of fat oxidation. Probiotics providing the conditions that cause lead to the release of iron from the tissues thus reducing the oxidation process (Kot, Furmanov, & Bezkorovainy, ). According to the results of this study, Kabploy et al () found that the addition of dietary ANT could decrease lipid oxidation; they suggested that ANT have high anti‐oxidative activity and decreasing MDA in tissue due to their ability to scavenge hydroxyl radical.…”

An experiment was conducted to investigate the supplementation of two commercially available multistrain probiotics as an alternative to antibiotics on growth performance, intestinal morphology, lipid oxidation and ileal microflora in broiler chickens. A total of 280‐day‐old ROSS 308 mixed‐sex broiler chickens with an average initial body weight of 42 ± 0.5 g were randomly divided into four treatments with five replicate cages of 14 birds each cage in a completely randomized design and fed with the following diets for 42 day: (a) control (CON) (antibiotic‐free diet), (b) antibiotic (ANT) (CON + Avilamycin 150 g/ton feed), (c) probiotic A (CON + Protexin® 150 g/ton feed) and (d) probiotic B (CON + Bio‐Poul® 200 g/ton feed). The results showed the broilers fed the ANT diet had greater average daily gain than broilers fed the CON diet during day 1–14 (p < 0.05). At day 42, two birds were randomly selected per replicate for evaluation intestinal morphology, lipid oxidation and ileal microflora. birds fed diet supplemented with probiotic A and probiotic B increased villus height and goblet cells numbers in the jejunum and villus height to crypt depth ratio and villus height in the ileum as compared to birds fed CON diet (p < 0.05). The malondialdehyde value was reduced (p < 0.05) in the ANT, probiotic B and probiotic A groups compared with the CON group. The Lactobacillus population was increased and Clostridium spp. population decreased in the ileum of broilers fed diets containing the probiotic B and probiotic A compared with those fed CON diet (p < 0.05). The results from this study indicate that the probiotic A (Protexin®) and probiotic B (Bio‐Poul®) used in this trial may serve as alternatives to ANT.

“…Although iron effectively reduced dipeptidase activity in pure cultures of P . albensis [ 208 ], the effect may be nullified in rumen fluid as lactobacilli can take up high amounts of iron [ 209 ]. Besides the effects on rumen bacteria, Brade et al [ 210 ] described defaunating effects of zinc-enriched diets in the rumen of dairy cows.…”

Nitrogenous emissions from ruminant livestock production are of increasing public concern and, together with methane, contribute to environmental pollution. The main cause of nitrogen-(N)-containing emissions is the inadequate provision of N to ruminants, leading to an excess of ammonia in the rumen, which is subsequently excreted. Depending on the size and molecular structure, various bacterial, protozoal and fungal species are involved in the ruminal breakdown of nitrogenous compounds (NC). Decelerating ruminal NC degradation by controlling the abundance and activity of proteolytic and deaminating microorganisms, but without reducing cellulolytic processes, is a promising strategy to decrease N emissions along with increasing N utilization by ruminants. Different dietary options, including among others the treatment of feedstuffs with heat or the application of diverse feed additives, as well as vaccination against rumen microorganisms or their enzymes have been evaluated. Thereby, reduced productions of microbial metabolites, e.g. ammonia, and increased microbial N flows give evidence for an improved N retention. However, linkage between these findings and alterations in the rumen microbiota composition, particularly NC-degrading microbes, remains sparse and contradictory findings confound the exact evaluation of these manipulating strategies, thus emphasizing the need for comprehensive research. The demand for increased sustainability in ruminant livestock production requests to apply attention to microbial N utilization efficiency and this will require a better understanding of underlying metabolic processes as well as composition and interactions of ruminal NC-degrading microorganisms.

“…The nature of this bond has been investigated in detail in Bifidobacteria ( Kot and Bezkorovainy 1991; Kot et al . 1994, 1995a; Bezkorovainy and Kot 1998), and it has been suggested that a ferroxidase is used to oxidize ferrous iron which is then stored as Fe 3+ in a particulate locus in the cell. Several factors were identified which could affect this ability (calcium and magnesium content of the growth medium, glucose, lactate, pO 2 and pH) in Bifidobacterium spp., as well as in Lact.…”

Iron requirement of Lactobacillus spp. in completely chemically defined growth media

A completely chemically‐defined growth medium, containing guanine, thymine, cytidine, 2′‐deoxyadenosine and 2′‐deoxyuridine as DNA precursors, was developed for Lactobacillus johnsonii, on the basis of statistically designed techniques suitable for other lactobacilli. Particular focus was given to the nucleotide composition of different defined media, and to the specific nucleotide requirements of Lact. johnsonii. Most of the lactobacilli tested grew in a medium containing five free bases, four ribonucleosides or five deoxyribonucleosides. Adenine and guanine were replaceable by inosine. The requirement for thymine and cytosine was satisfied with uracil. The presence of inosine and uracil was identified as being essential for the growth of different Lactobacillus species, displaying their inability to synthesize purines and pyrimidines de novo. Defined recipes with different nucleotide composition were used to investigate iron requirements of lactobacilli. Only marginal differences in growth were observed in iron‐depleted media supplemented with five free bases, four ribonucleosides or five deoxyribonucleosides; iron depletion had a greater effect on growth when inosine and uracil were supplied as the only nucleotide sources. The results suggest that iron plays a role in the pyrimidine and purine metabolism of lactobacilli. Lactobacillus spp., particularly Lact. johnsonii, require iron under particular environmental conditions with limited or specific nucleotide sources.
