Correction: Resource Availability Modulates the Cooperative and Competitive Nature of a Microbial Cross-Feeding Mutualism
Mutualisms between species play an important role in ecosystem function and stability. However, in some environments, the competitive aspects of an interaction may dominate the mutualistic aspects. Although these transitions could have far-reaching implications, it has been difficult to study the causes and consequences of this mutualistic-competitive transition in experimentally tractable syst...
متن کاملRecipient-Biased Competition for an Intracellularly Generated Cross-Fed Nutrient Is Required for Coexistence of Microbial Mutualists
Many mutualistic microbial relationships are based on nutrient cross-feeding. Traditionally, cross-feeding is viewed as being unidirectional, from the producer to the recipient. This is likely true when a producer's waste, such as a fermentation product, has value only for a recipient. However, in some cases the cross-fed nutrient holds value for both the producer and the recipient. In such cas...
متن کاملEffects of Matricaria chamomille and Cichorium intybus powder on Performance, Rumen Microbial Population and Some Blood Parameters of Dallagh Sheep
BACKGROUND: Manipulation of rumen microbial population for improving animal performance is done by several methods including medicinal plants. Matricaria chamomille (chamomile) and Cichorium intybus (chicory) are two medicinal plant with antibacterial effect that there is little information about the effects of them on rumen microflora. OBJECTIVE: The present study was carried out to evaluate t...
متن کاملوضعیت تغذیه کمکی در کودکان زیر یک سال مراجعهکننده به درمانگاههای ایلام
Background & Aim: Exclusive breast feeding is highly recommended for children under six months and the best time for starting supplementary food is the end of sixth months. Inadequate feeding can lead to malnutrition. Since infants;apos supplementary feeding pattern is influenced highly by the socio-cultural status it is necessary to study the subject in diverse conditions. This study aimed to ...
متن کاملEmergent cooperation in microbial metabolism
Mixed microbial communities exhibit emergent biochemical properties not found in clonal monocultures. We report a new type of synthetic genetic interaction, synthetic mutualism in trans (SMIT), in which certain pairs of auxotrophic Escherichia coli mutants complement one another's growth by cross-feeding essential metabolites. We find significant metabolic synergy in 17% of 1035 such pairs test...
