The article presents the materials of the study of the
features of cultivation of Lactobacillus sp. on
different culture medium. We have made a
comparison of standard culture medium for
cultivation Lactobacillus sp. and determined the
most optimal culture medium
This study has investigated the relationship between culture media, technique of concentrating and freeze drying conditions for the cells of Lactobacillus aci-dophilus. The study has demonstrated that milk whey tomato juice-enriched medium has the high-growth properties. This medium allows ensuring high freeze drying survival of Lactobacillus acidophilus
We have presented materials about nutrient media
for growing and industrial the cultivation of
Propionibacterium shermanii: Trypticase Yeast
Extract Glucose Medium, the culture medium
Ellinger and ATCC Medium 33. We have studied pH
change and its impact on the biomass accumulation
of propionic acid microorganisms. We have also
defined the best time of cultivation
The research work was conducted at the Research Laboratory
of Biotechnology, Biochemistry, Biophysics
Department of Kuban State Agrarian University. The
main purpose of this study was to select the most productive
type of fungus of a genus of Trichoderma and
optimal nutrient medium on basis of a waste of reprocessing
of soy for acquire of protein enzyme feed supplement.
For selection of a fungus of a genus
Trichoderma used 3 types: Trichoderma viride,
Trichoderma lignorum, and Trichoderma harsianum.
We used 3 types of nutrient media as a carrier for
micromycete, which were based on soy okara and the
additional sources of reprocessing of raw plant material
– husk of a sunflower, husk of wheat (bran) and
husk of rice. The results demonstrated the benefits of
using the nutrient medium based on soy okara forms
and husk of a sunflower fungus to enhance
Trichoderma lignorum production
The new feed additives for animals based on milk
whey, enriched with sprouting wheat, barley, maize
grains and lactic-acid bacterium have been presented
in this article. This study explores the possibility of
combining the prebiotics ability of milk whey and
sprouting grains with feed probiotic attributes of microbe
to enhance gut health of animals and digestibility
of the feed. Twelve variants of products were tested
in the study using the microbial and physical-chemical
approaches. All the assays showed high count of microorganism
and high content of reducing sugar. The
results of investigation indicate that selected feed additive
show high quality. An additional point is that it
contains useful organic acids (lactic, acetic and propionic
acids) and 2,1×109
colony-forming unit of probiotics
microorganism that hold the concentration for 4
months. There are not yeast, must, coliform bacteria
and Staphylococcus aureus in the developed functional
feed product. It contributes to the normalization of the
microflora of the gastrointestinal tract of animal, suppression
of conditionally pathogenic and putrefactive
microflora. The elaborated feed component will help
to provide combined feed companies with accessible
high-quality raw material
Rice blast caused by Pyricularia oryzae is a major disease affecting rice production grown in upland and wetland rice. Application of biotechnological approach to protect against the disease may be an alternative strategy to chemical control
