Optimisation of lactic acid fermentation from beet molasses by strain FD173
Beet molasses was used to produce lactic acid in this study. Effects of initial sugar concentration in beet molasses, inoculation of lactic acid bacteria, yeast extract concentration, temperature and time of fermentation on lactic acid generation were investigated. Orthogonal regress experiment design was adopted based on the single factor experimental results. Corresponding mathematical model ...

Effects of lactic acid bacteria (LAB) on the survival and growth of some food-borne pathogens in fermenting wakalim, a traditional Ethiopian fermented beef sausage
Wakalim is spiced naturally fermented traditional beef sausage in Ethiopia. During its fermentation using pure starter cultures of Lactobacillus plantarum1 or Pediococcus pentosaceus1 and mixture of the two starters, the counts of Salmonella typhimurium DT104 and Escherichia coli dropped sharply after 12 h of fermentation and complete elimination was noted on the third or fourth day. The count of ...

Preservation of fresh-cut 'Cavendish' banana coated with carrageenan and in controlled atmosphere
The objective was to study the effect of two controlled atmosphere (CA) compositions – 3% O2 and 6% CO2, and 3%O2 and 10% CO2 – on total counts of microorganisms at 30°C and 7°C, count of yeasts and moulds, count of enterobacteriaceae, and count of lactic acid bacteria of carrageenan coated fresh-cut 'Cavendish' banana. Bananas were previously submitted (or not) to a chemical dip of 1% calcium ...

Freeze drying of beads containing yeasts
Next to fermentation processes or transformation of foods, microorganisms such as Saccharomyces cerevisiae or lactic acid bacteria are of economic importance in the field of probiotic dietary food and feed supplements. These applications however require the preservation of cell viability during storage. By combining granulation and freeze drying, dust free particles, homogeneous in size and ...

Kinds of pig feed
The pig is an omnivorous animal, and its recipes can be said to be varied and eat everything. Pig feed can be divided into protein feed, energy feed, roughage, green feed, silage, mineral feed, feed additives, and vitamin feed if it is divided into eight categories according to nutrition. 1. Protein feed, 2. Energy feed, 3. Coarse feed, 4. Green feed, 5. Silage, 6. Mineral feed, 7. Feed ...

Microbial community composition and reactor performance during hydrogen production in a UASB reactor fed with raw cheese whey inoculated with compost
This study investigated the microbial community developed in a UASB reactor for hydrogen production and correlated it to reactor performance. The reactor was inoculated with kitchen waste compost and fed with raw cheese whey at two organic loading rates, 20 gCOD/Ld and 30 gCOD/Ld. Hydrogen production was very variable, using an OLR of 30 gCOD/Ld averaged 1.0 LH2/Ld with no methane produced under ...

Genetic variation and the effectiveness of early-generation selection for soft winter wheat quality and gluten strength
Selection for milling and baking quality in wheat (Triticum aestivum L.) head-rows could increase the efficiency of most soft winter wheat (SWW) breeding programs. We evaluated whole grain-wheat meal (WM) assays for their ability to select lines with acceptable SWW quality and high gluten strength in early-generations and estimated heritability of SWW quality and gluten strength. One hundred ...

Plasmid pcs1966, a new selection/counterselection tool for lactic acid bacterium strain construction based on the orop gene, encoding an orotate transporter from lactococcus lactis
In this paper we describe the new selection/counterselection vector pCS1966, which is suitable for both sequence-specific integration based on homologous recombination and integration in a bacteriophage attachment site. This plasmid harbors oroP, which encodes a dedicated orotate transporter, and can replicate only in Escherichia coli. Selection for integration is performed primarily by ...

Use of waste whey in tanning industry
The name of the deliming process suggests that the aim of the process is to remove the lime from the white hide. However, this is not complex enough. The primary purpose of the deliming procedure is to prepare the hide for bating and pickling. In order to do that, it is necessary to reach a suitable pH level to permit the bating enzymes to be active, and partially remove the excess lime. It is ...
