Early American publications relating to bacteriology.-I, Textbooks, monographs,
addresses, etc., L. S. MCCLUNG (Bact. Rev., 8 (1944), No. 2 pp. 119-160).
-"The Committee on Archives of the Society of American Bacteriologists is endeavoring
to collect regional histories of the beginnings of bacteriology in America.
... As a possible aid in this program, a compilation has been made of certain publications
that have appeared during the early years (through 1915)." Included in this
installment are an annotated alphabetical list of authors and the titles of their works
and a chronological list of authors.
Bacteria and rural water supplies, J. E. FULLER (Massachusetts Sta. Bul. 414
(1944), pp. 20).-"This is an attempt to give intelligent direction to what constitutes
sanitation in rural water supplies" and is based largely on experiments described in
detail which were conducted over several years to determine to what extent positive
laboratory tests actually mean dangerous pollution and how rigidly the "Standard
Methods" procedure and interpretation should be adhered to in evaluating the sanitary
quality of water from farms and other rural supplies. On the basis of experience
and the studies reported, it is concluded that the results of tests of untreated private
supplies must be interpreted liberally and emphasis placed on the presence of the
colon bacillus rather than on the aerogenes bacillus or intermediates of the coliform
group. It is desirable where possible to have a sanitary survey of the source of the
water tested. Studies of the several media for the presumptive and confirmation tests
failed to find any substitutes for the media specified in the Standard Methods for
these purposes. Certain intangible values were also derived from the study which
are not easily set down on paper-experience and a capacity for judgment that have
proved of substantial value in the doing of the work. Pertinent literature (21 references)
The use of alfalfa extract to supply nutrients for the growth and chemical
activities of Acetobacter suboxydans, E. I. FULMER, A. C. BANTZ, and L. A.
UNDERKOFLER (Iowa State Col. Jour. Sci., 18 (1944), No. 4, pp. 369-376).-Extracts
of alfalfa prepared by heating alfalfa meal with water or with dilute HC1 or NaOH
under various conditions supported the growth of A. suboxydans satisfactorily,
though not as well as yeast extract; best results were obtained with an acid extract.
A procedure is described for preparing a dry material from the alfalfa extract;
growth of the organism on a nutrient prepared from the best dry, preparation approached
that on an equal weight of yeast extract. The yields of keto-compounds
from the polyhydric alcohols, glycerol, sorbitol, and 2,3-butylene glycol were the
same when yeast or alfalfa extracts were used as nutrients.
The fermentability of the stereoisomeric 2,3-butanediols by Acetobacter
suboxydans, L. A. UNDERKOFLER, E. I. FULMER, A. C. BANTZ, and E. R. KooI
(Iowa State Col. Jour. Sci., 18 (1944), No. 4, pp. 377-379).-The authors demonstrated
that A. suboxydans oxidizes meso-2,3-butanediol and 1-2,3-butanediol to
acetylmethylcarbinol, but fails at attack the d-2,3-butanediol. This is another example
of the biochemical specificity of living organisms toward one of a pair of enantiomorphs.
Fermentations by streptothricin-resistant cultures of Aerobacillus polymyxa,
D. PERLMAN. (Univ. Wis.). (Jour. Bact., 48 (1944), No. 1, pp. 116-117).
Streptomycin, a substance exhibiting antibiotic activity against gram-positive
and gram-negative bacteria, A. SCHATZ, E. BUGIE, and S. A. WAKSMAN.
(N. J. Expt. Stas.). (Soc. Expt. Biol. and Med. Proc., 55 (1944), No. 1, pp. 66-69).
-Although most of the antibacterial agents produced by actinomycetes are active
against gram-positive bacteria, certain few of them also exert a marked selective
activity against many of the gram-negative types., Actinomyces lavendulae, producer
