Proteome and sugar catabolization capacity of Lactococcus cremoris grown on various sugars

ABSTRACT: The lactic acid bacterium Lactococcus cremoris is suggested to repress genes involved in sugar metabolism in a hierarchical way, correlating with the growth rate. For cultures grown on glucose, lactose, galactose and maltose, we unraveled the sugar catabolizing hierarchy by combining the proteome composition and the capacity to catabolize a set of 12 sugars.

<h4>Importance</h4>The availability of nutrients to microorganisms varies considerably between different environments, and changes can occur rapidly. As a general rule, a fast growth rate-typically growth on glucose-is associated with the repression of other carbohydrate utilization genes, but it is not clear to what extent catabolite repression is exerted by other sugars. We investigated the hierarchy of sugar utilization after substrate transitions in <i>Lactococcus cremoris</i>. For this, we ...[more]

Manganese availability alters the expression of its corresponding transporters and redox-dependent proteins but not superoxide dismutase in Lactococcus cremoris.

Project description:Growth of L. cremoris NCDO712 was not altered when manganese is omitted from its defined medium. This study was conducted in order to compare protein requirements of Lactococcus cremoris NCDO712 to grow in the presence or absence of manganese in defined medium (1% lactose). The majority of protein adaptation involves upregulation of Mn transporters and to a lesser extent various NADH-dependent proteins. Such adaptation is highly relevant for starter culture in dairy fermentation where manganese is limited and NADH homeostasis determines the formation of volatiles during long-term incubation e.g. cheese ripening.

Comparative analysis of the Trichoderma reesei transcriptome during growth on the cellulase inducing substrates wheat straw and lactose

Project description:We have examined and compared the transcriptome of T. reesei growing on wheat straw and lactose as carbon sources under otherwise similar conditions. Gene expression on wheat straw exceeded that on lactose, and 1619 genes were found to be only induced on wheat straw but not on lactose. They comprised 30 % of the CAZome, but were also enriched in genes associated with phospholipid metabolism, DNA synthesis and repair and iron homeostatis. Two thirds of the CAZome was expressed both on wheat straw as well as on lactose, but 60 % of it at least >2-fold higher on the former. Major wheat straw specific genes comprised xylanases, chitinases and M-CM-^_-mannosidases. Interestingly, the latter two CAZyme families were significantly higher expressed in a strain in which xyr1 encoding the major regulator of cellulase and hemicellulase biosynthesis is non-functional, demonstrating that XYR1 is a repressor of these genes. We used two biological replicas of four T. reesei strains growing on glucose, lactose, and on wheat straw

Characterization of the genes that were regulated by feeding with Lactococcus kimchii

Project description:In the present study, we investigated the effect of Lactococcus kimchii on healthspan using Caenorhabditis elegans as a model animal. The healthspan of the adult C. elegans fed the mixture of E. coli OP50 and Lactococcus kimchii was significantly longer than that of animals fed sole OP50 (control). Transcriptional profiling comparing Lactococcus kimchii- and control-fed animals suggested that genes related to insulin-like signaling pathway were upregulated by Lactococcus kimchii.

Lactococcus lactis stringent response

Project description:The stringent response was defined in Lactococcus lactis through transcript profiling after the addition of a chemical inductor, the norvaline. Gene expression was measured in the exponential growth phase (reference sample) and at 1.6 h after norvaline addition. Four hundred and sixty one differentially expressed genes were identified and constituted the stringent response regulon. Keywords: stress response, time course Stringent response was imposed through norvaline addition during the growth of Lactococcus lactis IL1403 under controlled conditions (30 Â°C, pH 6.6, nitrogen atmosphere). Cell samples were harvested in exponential phase and 1.6 h after norvaline addition. Total RNA was extracted from these samples and radiolabelled cDNA were prepared and hybridized on nylon arrays. 2053 amplicons specific of Lactococcus lactis IL1403 genes were spotted twice on the array. The 2 time-points were analyzed simultaneously and 3 independent repetitions were performed.

Molecular and physiological adaptations of Lactococcus lactis at near-zero growth rates

Project description:This paper describes the molecular and physiological adaptations of Lactococcus lactis during the transition from a growing to a near-zero growth state using carbon-limited retentostat cultivation. Metabolic and transcriptomic analyses revealed that metabolic patterns shifted between homolactic and mixed-acid fermentation during the retentostat cultivation, which appeared to be controlled at the transcription level of the corresponding pyruvate-dissipation enzyme pathway encoding genes. Furthermore, during extended retentostat cultivation, cells continued to consume several amino acids, but also produced specific amino acids subsets, which may derive from the conversion of glycolytic intermediates. Under conditions of extremely low carbon availability, carbon catabolite repression was progressively relieved and alternative catabolic functions were found to be highly up-regulated, which was confirmed by enhanced initial acidification rates on various sugar substrates in cells obtained from near-zero growth cultures. Moreover, the expression of genes involved in multiple stress response mechanisms was gradually induced during extended retentostat cultivation, supporting the strong molecular focus on maintenance of cellular function and viability. The present integrated transcriptome and metabolome study provides molecular understanding of the adaptation of Lactococcus lactis KF147 to near-zero growth rate conditions, and expands our earlier analysis of the quantitative physiology of this bacterium at near-zero growth rates. loop design of the samples including two shortcuts

Systemic analysis of lactose metabolism in Trichoderma reesei identifies a lactose permease that is essential for cellulase induction

Project description:Lactose (1,4-0-M-CM-^_-d-galactopyranosyl-d-glucose), a by-product from cheese manufacture or whey processing industries, is known to induce the formation of plant biomass hydrolyzing enzymes needed for the biorefinery industry in the fungus Trichoderma reesei, but the reason for this induction and the underlying mechanism are not fully understood. Here, we used systems analysis of the Trichoderma reesei transcriptome during utilization of lactose. We found that the respective CAZome encoded glycosyl hydrolases specifically tailored for the attack of monocotyledon xyloglucan. In addition, genes for a high number of putative transporters of the major facilitator superfamily were also induced. Systematic knock out of them identified a gene whose knock-out completely impaired lactose utilization and cellulase induction in Trichoderma reesei. These data shed new light on the mechanism by which Trichoderma reesei metabolizes lactose and illuminate the key role of M-CM-^_-D-galactosides in habitat specificity of this fungus. We used two biological replicas of Trichoderma reesei growing on lactose, glucose and glycerol
