STUDIES ON CERTAIN GROWTH PARAMETERS OF DIFFERENT PROBIOTIC STRAINS
Journal Title: Journal of Engineering Studies and Research - Year 2017, Vol 23, Issue 4
Abstract
The researchers found that probiotics contain microorganisms belonging to genus: Streptococcus, Lactobacillus, Bacillus, Aspergillus, Saccharomyces, Enterococcus, Pediococcus, enzymes (lactoperoxidase, gluconase, nonspecific enzymes) and rumen extracts. In this study, commercial probiotic bacteria known as "Linex" were used as samples. Cultural characteristics of these probiotic bacteria have been isolated and studied. It has been found that solid culture medium (nutritional gelose) favored the growth and development of bifidobacteria better than the liquid nutrient medium (nutrient broth). Thus, the number of bifidobacteria resulting from direct counting with Thoma chamber was of 7890 cells.
THE RELATIONSHIP BETWEEN THE ANTHROPOMETRIC MEASURES AND RESPIRATORY FUNCTIONS OF TOBACCO WORKERS
The aim of this research was to establish the relationship between some anthropometric measurements and peak expiratory flow rate of tobacco factory workers. Eighty permanent workers who had been employed for at least th...
NEW SELENATO TRIPHENYLTIN (IV) AND TRIMETHYLTIN (IV) DERIVATIVES: SYNTHESIS, INFRARED AND NMR STUDIES
Five derivatives of general formulae [cation] [SeO4SnR3] (R = Ph, Me) have been studied by infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy. The suggested structures are infinite chains or oligomers, the e...
COMPRESSIVE STRENGTH BEHAVIOUR OF CONCRETE PRODUCED USING OKIGWE RED LUMP STONE AS COARSE AGGREGATE
This study was carried out in order to ascertain if the Okigwe red lump stone, found in South-eastern Nigeria, could be used as coarse aggregate in making structural concrete. The maximum compressive strength values, obt...
A COMPARATIVE STUDY BETWEEN WATER-GAP AND AIR-GAP DISTILLATION MEMBRANES FOR REMOVAL OF SALTS FROM SALINE WATER BY DESALINATION METHOD
The water deficit for consumption in various daily activities is more pronounced especially in countries where rainfall is low or in those areas where water demand is higher than available resources. This paper is a comp...
EVALUATION OF THE MODEL PREDICTION TOXICITY (LD50) FOR SERIES OF 42 ORGANOPHOSPHORUS PESTICIDES
Structure-Toxicity Relationships have been studied for a set of 42 organophosphorous pesticides (OPs) through multiple linear regression (MLR) and artificial neural networks (ANN). A model with three descriptors, includi...
