Fermentation 
fiddle-shaped 
ferments, particularized as ace’tic 
~, produced by Bacterium Aceti, 
Lanzi; alcoholic ~, by yeast, 
and similar organisms ; butyr’ic~, 
by a Vibrio; lae’tic ~, by which 
sugars are turned into acids; an- 
other classification is (1) diastat’ic 
~, converting starch into sugar ; (2) 
ferments which decompose gluco- 
sides with production of sugar, 
such as emulsin; (3) ferments 
which convert cane-sugar into glu- 
cose, as invertase; (4) and those 
which convert proteids into 
peptones, or peptic ~, such as 
papain.

tiliza’tion, Fertilisa’'tio, impregna- 
tion of the ovules by pollen; ~

lated parents ; Cross ~, progeny by 
other forms not of close affinity. 
ferula’ceous, ferula’ceus (Lat.) (1) re- 
sembling the genus Ferula ; (2) per- 
taining to reeds or canes, or being

tive of Fipre; ~ of Nu’cleus =

la‘tus, fi’brillose, fi’ brillous, fibrillo’- 
sus, furnished with fibres, as roots, 
or having a finely lined appearance ; 
~Lay’er, two outer layers of closely 
woven hyphae in Geaster ; ~Myce’- 
lium = Frprous Myceium ; Fi’brin 
(vegetable), occurs in gluten, has 
no fibrous structureas animal fibrin, 
but forms when dry a tough, horny 
mass; fi’bro-cel’lular, ‘‘ composed 
of spiral cells”’ ; ~ va’sal (Crozier) 
~ vase’ular, tissue of mixed 
vessels and fibres; ~ Bun'dle, 
or Vascular Bundle, an association 
of vessels characteristic of the 
higher plants, usually consisting 
of phloém and xylem elements, 
often surrounded by a special layer 
of cells known as the bundle-sheath; 
~ Cord, proposed by Strasburger 
for the similar structure in mono- 
cotyledons ; ~ Cylinder, the central 
cylinder ; ~ Sys’‘tem, the whole of 
the fibrous portion of a plant, ex- 
clusive of the purely cellular struc- 
tures ; Fibrole’in, Fayod’s term for 
a very delicate membrane of the 
spirals of protoplasm (hyaloplasm) ; 
fi’brous, fi'brose, jibro’sus, having 
much woody fibre, as, the rind of 
a Coco-nut; Fibrous - myce’lium,
