1. Effect of alcohols on filamentation, growth, viability and biofilm development in Candida albicans
In this study we report the potential of alcohols as morphogenetic regulators in Candida albicans. All the alcohols tested influenced various modes of growth like planktonic as well as biofilm forms. Viability was affected at high concentrations. Among the alcohols, the response of C. albicans to amyl alcohol (pentanol) was noteworthy. Amyl alcohol at a conc

2. Relação dos sistemas de reparo de DNA em Escherichia coli K-12 com resistência a antibióticos, características adesivas e formação de biofilme / Relation of DNA repair systems in Escherichia coli K-12 with antibiotic resistance, adhesive characteristics and biofilm formation
As espécies reativas de oxigênio (ERO) são geradas durante o metabolismo celular normal e podem produzir vários danos oxidativos no DNA, tais como lesões nas bases nitrogenadas ou sítios apurínico/apirimidínico (AP). Essas lesões podem acarretar acúmulo de sítios de mutações, caso esses danos não sejam reparados. Entretanto, as bactérias possu

3. Características da formação do biofilme de Candida tropicalis eresistência a antifúngicos
Candida tropicalis is a common non-albicans species related to nosocomial candidemia and candiduria. Most of Candida spp. infections are associated with biofilm formation on the implanted medical devices or host ephitelial cells surfaces. Sessile cells display phenotypic traits dramatically different from their free-living planktonic counterparts, such as in

4. Inhibition of Candida albicans Biofilm Formation by Farnesol, a Quorum-Sensing Molecule
Farnesol is a quorum-sensing molecule that inhibits filamentation in Candida albicans. Both filamentation and quorum sensing are deemed to be important factors in C. albicans biofilm development. Here we examined the effect of farnesol on C. albicans biofilm formation. C. albicans adherent cell populations (after 0, 1, 2, and 4 h of adherence) and preformed

5. Reduced Water Availability Influences the Dynamics, Development, and Ultrastructural Properties of Pseudomonas putida Biofilms
Pseudomonas putida strain mt-2 unsaturated biofilm formation proceeds through three distinct developmental phases, culminating in the formation of a microcolony. The form and severity of reduced water availability alter cell morphology, which influences microcolony size and ultrastructure. The dehydration (matric stress) treatments resulted in biofilms compr
