Surfactants are amphiphilic molecules with a worldwide billionaire market. Although chemical surfactants are the most available and commonly used, the microbiologically produced congeners have attracted attention due to their low toxicity, biodegradability, and high ecological acceptability. Among microbial surfactants rhamnolipids stand out, with high yields of production, excellent surface-active properties and great potential market. However, the application of these compounds is still limited mostly because of excessive production costs. This study presents a cost-effective process for rhamnolipids production by semi-submerged static-cultivation using agar cubes as substrate. A concentration of 50 g/L of rhamnolipids was reached in semi-submerged static-cultivation using agar cubes containing corn bran and soybean oil. Through this static process, besides avoiding foam, gradual release of nutrients provides a large increase in P. aeruginosa growth and consequently on rhamnolipids production.

To test the hypothesis that single nucleotide polymorphisms (SNPs) in the muscle-related genes actinin alpha 3 (ACTN3), creatine kinase muscle (CKM), and angiotensin I converting enzyme (ACE) are associated with sleep bruxism (SB). This study involved 45 individuals diagnosed with SB through self-report questionnaires, clinical examination, and polysomnography. Deoxyribonucleic acid samples were collected, and three SNPs, rs1815739 in ACTN3, rs8111989 in CKM, and rs4341 in ACE, were selected for genotyping via real-time PCR. The associations between SB and SNPs were investigated with genotypic, allelic, recessive, and dominant models via the χ2 test. Associations between SNPs and SB were estimated by odds ratios (ORs) with 95% confidence intervals (CIs), with significance considered when p < 0.05. Sixteen individuals, 11 males (68.7%) and 5 females (31.3%), were diagnosed with SB. Another 29 individuals (16 males and 15 females) without bruxism were included in the control group. For rs1815739, the CC genotype was associated with a high prevalence of SB (p = 0.032). In the recessive model, homozygous CC individuals presented 392% greater odds for SB than individuals with CT/TT (OR 4.92; 95%CI 1.29–18.73). No differences were observed for rs8111989 and rs4341 in the tested models (p > 0.05). Polymorphism rs1815739 in ACTN3 was associated with SB.

Staelia (Rubiaceae) is a genus endemic to South America identified by the unique capsule that splits into three parts. In Brazil, the genus thrives in diverse habitats in the Caatinga, Cerrado, and Campos Rupestres. Fieldwork carried out in the ecotone between these dominia, in areas of the municipality of Monte Azul, Minas Gerais, evidenced a new microendemic plant species, mainly recognized by its numerous stipular fimbriae on the stem, naming the new Staelia we describe here. We provide an illustration, photographs of the species and its habitat, a preliminary conservation assessment, as well as a comparison with similar species.
