e supra descriptum est molecula autoinducer, quae 1,3-diaminopropane (1,3-DAP) notatur, a Penicillio chrysogenum et Acremonium chrysogenum secernitur.Utens culturas fermentor pH-continens in hoc opere observavimus quod 1,3-DAP et spermidine clare incitant biosynthesim benzylpenicillin in P. chrysogenum, tam in definitis quam in complexu instrumentorum productionis penicillinorum.Ambae 1,3-DAP et spermidine, sed non putrescina (1,4-diaminobutana), acrem augent in transcripto graduum genesis penicillini biosynthetici pcbAB, pcbC et penDE.Hae polyamines expressionem pH-accentoris regulatoris pacC generum globalis non afficiunt, ita excluso quod effectus 1,3-DAP et spermidine debetur modificationi mechanismi pH.Expressio trium generum penicillinorum biosyntheticorum vehementissime reducitur in laeA-pulsante mutante P. chrysogeni, quae nimis humiles gradus benzylpenicillini producit.Interestingly, 1,3-DAP et spermidine reverti t facit effectum mutationis laeA pulsantis, gradus productionis penicillinae omnino restituens.Praeterea, 1,3-DAP et spermidine amplificata expressionem laeA in contentionem parentalem et gradus laeae transcriptorum in laeA pulsato mutant.Hi eventus coniunctim indicant effectum stimulatorium inducentis molecularum 1,3-DAP et spermidinem qnam, saltem ex parte, per excitationem expressionis laeA, moderatoris globalis qui epigenetice agit in expressione metaboliti genes secundae. per heterochromatin ordinationem.
