Production of food grade β-galactosidase from artisanal yogurt strains
(Taylor & Francis, 2010-01)
Superior artisanal isolates of thermophilic lactic acid bacteria producing high lactic acid and β-galactosidase were isolated from traditional Turkish yogurt samples from the Toros mountain region from a highly bio-diverse ...
Use of UV-C radiation as a non-thermal process for liquid egg products (LEP)
(Elsevier, 2008-04)
The efficacy of short wave ultraviolet light (UV-C) as a non-thermal process for liquid egg products (LEP) was investigated. Non-pathogenic Escherichia coli strain (ATCC 8739), which shows lower sensitivity to UV-C light ...
Colloid deposition experiments as a diagnostic tool for biomass attachment onto bioproduct adsorbent surfaces
(Wiley, 2008-02)
Background: Detrimental processing conditions can be expected in any downstream operation where direct contacting between a crude feedstock and a reactive solid phase is supposed to occur. In this paper we have investigated ...
Characterization of three-phase partitioned exo-polygalacturonase from Aspergillus sojae with unique properties
(Elsevier, 2008-04)
Exo-polygalacturonase enzyme produced by Aspergillus sojae ATCC 20235 was purified using three-phase partitioning (TPP), an emerging bio-separation technique where a single step as compared to the classical multi-step ...
Dilute-acid hydrolysis of apple, orange, apricot and peach pomaces as potential candidates for bioethanol production
(American Scientific Publishers, 2013-07)
Chemical composition of four selected fruit pomaces (agro-industrial wastes) was evaluated. The effect of temperature, time, acid concentration and solid:liquid (S:L) ratio on dilute-acid hydrolysis of selected pomaces ...
Surface energetics to assess biomass attachment onto hydrophobic interaction adsorbents in expanded beds
(Elsevier, 2009-01)
Cell-to-support interaction and cell-to-cell aggregation phenomena have been studied in a model system composed of intact yeast cells and Phenyl-Streamline adsorbents. Biomass components and beaded adsorbents were characterized ...
Modeling of polygalacturonase enzyme activity and biomass production by aspergillus sojae ATCC 20235
(Springer, 2009-09)
Aspergillus sojae, which is used in the making of koji, a characteristic Japanese food, is a potential candidate for the production of polygalacturonase (PG) enzyme, which of a major industrial significance. In this study, ...
Optimization of the associative growth of novel yoghurt cultures in the production of biomass, β-galactosidase and lactic acid using response surface methodology
(Elsevier, 2009-04)
The associative growth of Streptococcus thermophilus 95/2 (St 95/2) and Lactobacillus delbrueckii ssp. bulgaricus 77 (Lb 77) isolated from the Toros mountain region of Turkey was investigated with respect to lactic acid, ...
Effect of various process parameters on morphology, rheology, and polygalacturonase production by Aspergillus sojae in a batch bioreactor
(American Institute of Chemical Engineers, 2007-07)
The effects of pH, agitation speed, and dissolved oxygen tension (DOT), significant in common fungal fermentations, on the production of polygalacturonase (PG) enzyme and their relation to morphology and broth rheology ...
Optimization of a growth medium using a statistical approach for the production of an alkaline protease from a newly isolated Bacillus sp. L21
(Elsevier, 2006-03)
Bacillus sp. L21 was isolated from the by-products of a leather factory (located in Izmir, Turkey) working under extreme alkaline conditions. Its phenotypic and genotypic identifications were completed, and determined as ...
