“…There was no clear distinction between pseudomonads, Alcaligenes, Moraxella, Achromobacter, CDC group IVe and Flauobacterium by means of this system. To clarify part of this situation the key according to Tilton (1981) using the O/F reaction with glucose was applied. In the list of synonyms and mixed taxa of the API NE20 analytical profile index CDC group IVe was stated to be equivalent to Alcaligenes.…”

At a city abattoir, a wholesaler and 10 different supermarkets, surface microbiological samples were taken of carcasses, hands and apron fronts of members of staff and equipment (mincers and saws). In addition, minced meat, packaged and displayed in chilled cabinets, was also sampled. Carcasses, personnel surfaces and equipment were monitored by a modified agar sausage technique. From each of the highest dilution psychotrophic plate counts, five colonies were selected randomly, isolated and identified (1265 in total). Microbes developing on chilled meat were also isolated from other surfaces in the production chain. On chilled meat (51%) and at the abattoir (36%) pseudomonads were the predominant organisms followed by the Gram-positive cocci on chilled meat and by Acinetobacter, Moraxella and Alcaligenes spp. at the abattoir. At the wholesaler Gram-positive cocci (32%) predominated, followed by Alcaligenes, Moraxella and Alcaligenes spp. Pseudomonas, Alcaligenes, Neisseriaceae and related genera, Gram-positive cocci, species from the coryneform groups of bacteria and yeasts were identified from all the surfaces monitored. Identification with the API NE20 was unsatisfactory. Enterbacteriaceae, lactobacilli and endospore-forming bacteria were identified occasionally, but their significance as contaminating organisms seems low. No Salmonella spp. were identified.

A D-aminoacylase-producing microorganism, strain DA181, isolated from soil was identified as Alcaligenes denitrifcans subsp. denitrificans. This strain produced about 29,300 units (micromoles of product formed per hour) of D-aminoacylase and 2,300 units of L-aminoacylase per gram of cells (wet weight) when cultivated in a medium containing 1% N-acetyl-DL-leucine as the carbon source. The D-aminoacylase was purified 345-fold. The specific activity of the purified enzyme was 108,600 units per mg of protein when N-acetyl-D-methionine was used as a substrate. The apparent molecular weight was 58,000, as estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. N-Acetyl-D-methionine was the favored substrate, followed by N-acetyl-D-phenylalanine. This enzyme had a high stereospecificity, and its hydrolysis of N-acetyl-L-amino acids was almost negligible.
