Beneficial bacteria for aquaculture: nutrition, bacteriostasis and immunoregulation

Aquaculture Nutrition

Dietary enrichments with the arachidonic acid (ARA)-rich microalga, Parietochloris incisa, on the survival of guppy (Poecilia reticulata) fry were examined. Diets were applied via Artemia enrichment to fish from two commercial farms for 34 and 36 days of experimental period (trials 1 and 2, respectively). In trial 1, Artemia nauplii were enriched with dry biomass of whole algal cells at 0 (cont...

Aquaculture Nutrition

Apparent amino acid availability coefficients of several typical and novel feed ingredients were determined in rainbow trout using extruded diets and the faecal stripping technique. The ingredients were tested included five fish meals, three terrestrial animal by-products, five plant protein concentrates, four plant meals, and seven low-protein plant ingredients. Amino acid availability from th...

An amine ed formed by bacteria during sulfonamide bacteriostasis.

When Escherichia coli was grown in a synthetic medium containing salts, amino acids, and glucose in the presence of bacteriostatic concentrations of sulfonamides, an increase in total diasotizable amine was noted (1). This has nolv been found to be due to the production of a new heterocyclic amine, the nature of mhich may ultimately throIv light on the mechanism of sulfonamide bacteriost,asis. ...

Beneficial bacteria inhibit cachexia

Muscle wasting, known as cachexia, is a debilitating condition associated with chronic inflammation such as during cancer. Beneficial microbes have been shown to optimize systemic inflammatory tone during good health; however, interactions between microbes and host immunity in the context of cachexia are incompletely understood. Here we use mouse models to test roles for bacteria in muscle wast...
