probiotics, living microorganisms which when used in adequate amounts, have health benefits on the host, have attracted a considerable deal of interest in the biotechnology market. various prokaryotic and eukaryotic microbes have been studied for probiotic purposes in human and animals. lactobacillus and bifidobacterium are the main probiotic genera; however, there are reports on the probiotic p...

Background: Enhancing the industrial yeast strains ethyl acetate yield through a precise and seamless genetic manipulation strategy without any extraneous DNA sequences is an essential requisite and significant demand. Objectives: For increasing the ethyl acetate yield of industrial brewer’s yeast strain, all the ATF1 alleles were overexpressed t...

background and objectives: lipases are particularly important due to the fact that they specifically hydrolyze acyl glycerol, oils and greases, which is of great interest for different industrial applications. materialst and methods : in this study, several lipase-producing bacteria were isolated from wastewater of an oil processing plant. the strain possessing the highest lipase activity was i...

The composition of cultivation media in relation to strain development for industrial application is reviewed. Heterologous protein production and pentose utilization by Saccharomyces cerevisiae are used to illustrate the influence of media composition at different stages of strain construction and strain development. The effects of complex, defined and industrial media are compared. Auxotrophi...

The Aspergillus aculeatus rhaA gene encoding an alpha-L-rhamnosidase has been expressed in both laboratory and industrial wine yeast strains. Wines produced in microvinifications, conducted using a combination of the genetically modified industrial strain expressing rhaA and another strain expressing a beta-glucosidase, show increased content mainly of the aromatic compound linalool.

Penicillium chrysogenum is the major industrial producer of the β-lactam antibiotic penicillin. Here, we report the complete genome sequence of the industrial progenitor strain P. chrysogenum P2niaD18 in a chromosome-scale genome assembly. P2niaD18 is distinguished from the recently sequenced P. chrysogenum Wisconsin 54-1255 strain by major chromosomal rearrangements leading to a modified chrom...

AIMS Construction of an industrial brewer's yeast strain, which could improve foam stability and reduce calorific values of beer. METHODS AND RESULTS An industrial brewer's yeast strain (Ts-10) was constructed by integrating glucoamylase encoding gene GAI amplified from Saccharomycopsis fibuligera by PCR into the locus of proteinase A (PrA) gene (PEP4). The resulting recombinant strain identi...
