What factor contributes to the difference in the appearance of isolated versus crowded colonies?

1. The factors that contribute to the differences in appearance of isolated vs crowed colonies are: 1. Availability of nutrients, where colonies are crowed the bacteria will be in competition for nutrients and because of this there can be a reduction of size and shape also growth can also be stunted whereas in isolated colonies the nutrients is readily available with no competition for nutrients. 2. space, isolated colonies have more space to grow as compared to crowded colonies and 3. If there is contamination in a crowded colony the texture will be very difficult to determine however texture can be viewed in isolated colonies so contamination is a factor.

Will isolated colonies always be in the second sector on the streak plate?

No. It depends on the number of bacteria present in the initial sample. If the number of bacteria in the initial sample are limited, you may get isolated colonies in the first streak. If the number of bacteria in the sample are high, it may take several streaks before the sample is diluted to the point where isolated colonies are evident.


Will isolated colonies of bacteria always be in the fourth sector on the streak plate?

No, of course it is possible that one could start out with an already diluted sample in the first step. So then perhaps in the third sector some isolated colonies may form, because the amount of bacteria have been diluted enough.
