Other claims from this paper (8)
- Observation Nonencapsulated wild-type yeast hydrophobicity and adhesiveness decreased from mid-log to late stationary phase.
- Observation Encapsulated wild-type yeast was more hydrophobic and adhesive than nonencapsulated cells.
- Observation Two encapsulated attachment-minus mutants were more hydrophobic than wild type.
- Observation Yeast adhesion levels were similar on polystyrene and less hydrophobic glass.
- Observation Sixteen attachment-minus mutants lacked a positive surface charge.
- Observation Wild-type cells failing to attach to CM-Sephadex also failed to adhere to polystyrene or barley.
- Observation Wild-type yeast attached to CM-Sephadex by cell poles, indicating localized positive charge also visualized with India ink.
- Mechanism Localized positive charge rather than hydrophobic interactions mediates yeast attachment to barley leaves.
