✦ Synopsis

Washings from long staple cotton (Gossypium barbadense L.) new variety Barakat, yielded Aspergillus flavus, A. nidulans, A niger. A. terreus, A. versieolor and Cladosporium herbarum. The number of propagules increased with R. H. following 6 month-storage. A. terreus was less favoured.

Higher R. H. impaired fibre length and strength of both raw non-sterilized and inoculated sterile lint whilst the sterilized non-inoculated control was insignificantly affected, even at 100% R.H. Artificial inoculation of lint with Chaetomium globosum and A. nidulans significantly affected the efficiency of yarn spinnability at 80, 90 and 100% R.H. (P : 0.05).

Hyphae, which wound in a helical pattern around the fibre, intermittently dissolved fibre wall causing fibre fragility.
