“…As P. aeruginosa biofilms grow, the cells remain nonmotile, but at maturity, mushroom-like pillars separated by water channels form within the biofilms, which contain motile cells that exit in the process of dispersal (81,118,123,124). Not only the size of the biofilm but also multicellular morphogenesis is regulated by quorum sensing (125)(126)(127). Cell death, which plays a major role in vertebrate development, most notably in limb formation (128,129), may also play a role (130)(131)(132).…”

SUMMARYCandida albicans, the most pervasive fungal pathogen that colonizes humans, forms biofilms that are architecturally complex. They consist of a basal yeast cell polylayer and an upper region of hyphae encapsulated in extracellular matrix. However, biofilms formedin vitrovary as a result of the different conditions employed in models, the methods used to assess biofilm formation, strain differences, and, in a most dramatic fashion, the configuration of the mating type locus (MTL). Therefore, integrating data from different studies can lead to problems of interpretation if such variability is not taken into account. Here we review the conditions and factors that cause biofilm variation, with the goal of engendering awareness that more attention must be paid to the strains employed, the methods used to assess biofilm development, every aspect of the model employed, and the configuration of theMTLlocus. We end by posing a set of questions that may be asked in comparing the results of different studies and developing protocols for new ones. This review should engender the notion that not all biofilms are created equal.

“…Despite recent advances in microbial ecology for analyzing microbial phylogeny and physiology in the natural environment, we know little about how microbes interact with each other and how microbial interactions influence community structures and functions. Our knowledge of the cooperative and synergistic interactions (9,23,26,49,60) which help microbes to survive in complex microbial communities, is particularly limited.…”

In natural and engineered ecosystems, diverse species of microbes coexist and interact, resulting in the emergence of community functions. Since microbes have evolved under such circumstances, it is reasonable to deduce that they have acquired strategies for specific interspecies interactions in complex microbial communities. In this review, we discuss the ecological and evolutionary interactions in syntrophic methanogenic consortia comprised of organic acid-oxidizing bacteria and methanogenic archaea. These microbes are known to exhibit mutual interactions (syntrophy), although the molecular mechanisms underlying these sophisticated partnerships have only just been discovered. In addition, recent genomic studies have provided insights into evolutionary interactions among members of methanogenic consortia, from which a novel concept termed "niche-associated evolution" has been proposed for interpreting how specialists evolve in a biological community. We suggest that microbial interspecies interactions are much more complex and sophisticated than hitherto realized and pivotal to the development and functioning of microbial communities.

“…Quorum sensing (QS) is known as a cell-to-cell communication process widely observed among prokaryotes, when bacteria ensure an appropriate coordination by communicating through signal molecules [1][2][3]. More than 70 species of Gram-negative bacteria have been shown to produce acylated homoserine lactones (AHLs), which play a very important role in gene regulation, including biofilm formation and virulence factors in many pathogenic bacteria [4][5][6][7][8].…”

aiiA gene encoding AHL-lactonase was isolated from Bacillus cereus strain N26.2, originating from a striped catfish (Pangasianodon hypophthalmus) pond in Vietnam. This gene, abbreviated as aiiA(N26.2), was cloned and expressed in a competent Escherichia coli strain BL21(DE3)pLysS. The resulting protein, abbreviated as AiiA N26.2 , was highly active in the pH range of 6-8 and could retain 80 % of the maximum activity under storage for 5 days at 4°C or for 3 days at 20°C. These properties of AiiA N26.2 protein confers its future application via feed supplementation, with the purpose of controlling aquaculture pathogens which regulate the virulence via a quorum sensing system.
