Lactic acid bacteria (LAB) is mainly used as an alternative
to antibiotics in poultry production to control infection
with enteric pathogens, enhance productivity and improve
food safety. Over 89 presumptive LAB were isolated from
chicken samples collected during the four seasons. Eleven
representative strains were chosen and were screened for
their probiotic potential through in vitro assessment of their
tolerance to acidic pH, bile salts, and antibiotics, bacteriocin
production, and antagonistic activity against selected enteric
pathogens. The selected LAB strains showed strong potential
for the development of commercial probiotic products. The
main objectives of this study are: to develop a cost-effective
media, and the conceptual design for the commercial
production including downstream processing, product
formulation, final product assessment on live chicken, shelf-
life evaluation of the final product, and to assess the techno
economic feasibility of commercial product. Five isolates from
the eleven strains have been identified as potential candidates
for the development of poultry probiotics, these isolates
are: Lactobacillus plantarum; Lactobacillus parabunchner;
lactobacillus reutreri; Lactobacillus brevis; and Pediococcus
pentosaccus. However, before the commercial production
probiotics is considered, the compatibility test between these
isolates have been assessed.
Speaker Biography
Tahani Al-Surrayai joined the Biotechnology Dept. at KISR in 1995 as a
Research Assistant. During the past twenty four years, she developed
excellent technical skills and has actively participated in several important
research projects in the area of Environmental Biotechnology. Her role in
the many projects resulted successfully in the isolation, characterization
and optimization of a large number of new microbial strains from the
local environment. These strains have been used as an integral part of the
developed sulphur amendment for enhancing soil fertility. Additionally,
She leads a task in a study that focused on the screening and evaluation
of PAHs degrading microorganisms for the local environment. Besides
her depth of knowledge and skills in biochemistry and microbiology, she
involved in the development of probiotic bacteria for use in livestock
and poultry. Accordingly, she has been leaded two successful projects in
probiotics fields for livestock.
