## Abstract Poly(3βhydroxybutyrate), PHB, is a widely distributed carbon storage polymer among prokaryotes including __Rhizobium__. Capacities of __Rhizobium etli__ R13 to produce the bioplastic during growth on media with different carbon sources appeared to be specific carbonβsource. In fed batch

The complex dielectric constant of collagen in aqueous solutions (polymer concentration, C, = 0.02-0.2%) was measured a t 10Β°C in the frequency range from 3 Hz to 30 kHz. The loss peak for C, = 0.02% is located a t 90 Hz and the dielectric relaxation time rn is estimated to be 1.8 f 0.3 msec. The TL
## Abstract Real and imaganiry parts of complex dielectric constant of dilute solutions of DNA in 10^β3^__M__ NaCl with molecular weight ranging from 0.4 Γ 10^6^ to 4 Γ 10^6^ were measured at frequencies from 0.2 Hz to 30 kHz. Dielectric increments ΞΞ΅ were obtained from ColeβCole plots and relaxati
