In consequence, spiroplasmas show ‘viscotactic’ behaviour in viscosity gradients. Motility is energy-dependent and is optimal at pH 7. It has also been found that spiroplasmas are capable of chemotaxis, being attracted towards sugars and some amino acids and repelled by hydrophobic amino acids, some organic acids and heavy metals., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-118-2-429
