Different carriers used for inoculant production
Carrier material
Inoculant bacterium Characteristics
Sterilized oxalic acid industrial
waste
Rhizobium
Seed inoculation;
Rhizobium
multipli-
cation in carrier in ambient tem-
perature up to 90 days; carrier
sterilization resulted in significant
increase in grain yield, nodule
number and N content
Alginate-perlite dry granule
Rhizobium
Soil inoculation;
Rhizobium
strains
survived in dry granules beyond
180 days; the inoculant can be
stored in a dry state without losing
much viability
Composted sawdust
Bradyrhizobium,
Rhizobium
and
Azospirillum
Seed inoculation; good growth and
survival of the inoculant strains
Agriperlite, expanded clay, kaolin,
Celite, Diatom, porosil MP,
MicroCel, vermiculite
Agrobacterium
radiobacter
K84
Crown gall control. Screening was
performed to find improved for-
mulation of K84 cells; effect of
carrier storage temperature and
carrier water content on survival of
K84 was examined
Cheese whey grown cells in peat
Rhizobium meliloti
Seed inoculation; better survival at
various temperature during storage
even under desiccation
Mineral soils
Rhizobium
Seed inoculants;
Rhizobium
survived
better at 4
C than at higher
temperature
Coal/charcoal
Rhizobium/
PS
bacteria
Seed inoculants
Granular inoculants amended with
nutrients
B. japonicum
Soil inoculants; bentonite granules,
illite and smectite granules, silica
granules amended with glycerol,
Na glutamate and inoculated with
either peat or liquid
B. japonicum
inoculants; enhanced early nodula-
tion of soybean and increased N
content of grain
Soybean oil or peanut oil added
with lyophilized cells
Rhizobium
Seed inoculants; provide more protec-
tion than peat-based inoculants
when rhizobia are inoculated on
seeds and exposed to condition of
drought and high temperature
Rhizobium,
Bradyrhizobium,
Bacillus
Perlite
Seed inoculants; combination of a
sucrose adhesive with the perlite
carrier gave better survival of bac-
teria on seeds; produced similar
number of nodules, nodule dry
weight, crop yield and nitrogen
content as peat-based inoculants
